Abstract: Inorganic nanoparticles based on magnetite improve the mechanical, thermal, and magnetic properties of microporous cryogel polymer composites.
Here we report the synthesis of microporous cryogel based on the crosslinked sodium vinyl sulfonate (Na-VS) and 2-acrylamido-2-methylpropane sulfonic acid sodium salt (Na-AMPS).
The magnetite nanoparticles were inserted into Na-VS/Na-AMPS cryogel either during its crosslinking polymerization or by in-situ technique after its crosslinking.
The morphology, particle sizes, thermal stability and magnetite contents of Na-VS/Na-AMPS cryogel and its magnetite composites were investigated.
The prepared Na-VS/Na-AMPS cryogel and its magnetite composites were used as adsorbents for methylene blue (MB) cationic dye using optimum conditions.
The magnetite Na-VS/Na-AMPS cryogel composite prepared by in-situ technique achieved the best adsorption MB removal capacity for 7 cycles among the other adsorbents via chemical adsorption mechanism at room temperature.

Acrylamido-2-methylpropane sulfonic acid AMPS CAS 15214-89-8 is a reactive, hydrophilic, sulfonic acid acrylic monomer used to alter the chemical properties of wide variety of anionic polymers.
AMPS is a kind of vinyl monomer with sulfonic acid group, which has a good thermal stability.
The decomposition temperature can be up to 210 and the temperature of sodium salt copolymer can reach
AMPSs hydrolysis is very slow in aqueous solution.
Sodium salt solution has good anti-hydrolysis performance with high PH value.
Under acid condition, the hydrolysisresistant performance of its copolymer is better than that of polyacrylamide.
The monomer can be made into crystal or sodium salt solution.
AMPS is used in many areas including water treatment, oil field, construction chemicals, hydrogels for medical applications, personal care products, emulsion coatings, adhesives, and rheology modifiers.

Properties of AMPS

Hydrolytic and thermal stability: The geminal dimethyl group and the sulfomethyl group combine to sterically hinder the amide functionality and provide both hydrolytic and thermal stabilities to AMPS-containing polymers.
Polarity and hydrophilicity: The sulfonate group gives the monomer a high degree of hydrophilicity and anionic character at wide range of pH.
In addition, AMPS is absorbing water readily and also imparts enhanced water absorption and transport characteristics to polymers.
Solubility: AMPS is very soluble in water and dimethylformamide (DMF) and also shows limited solubility in most polar organic solvents.
Inhibition of divalent cation precipitation: Sulfonic acid in AMPS is a very strong ionic group and ionizes completely in aqueous solutions.
In applications where the precipitation of mineral salts is undesirable, the incorporation of a polymer containing even a small quantity of AMPS can significantly inhibit the precipitation of divalent cations.

Application of AMPS

– Acrylic fiber
– Coating and adhesive
– Detergents
– Personal care
– Medical hydrogel
– Oil field applications
– Water treatment applications
– Crop protection
– Membranes
– Construction applications

Anionic charges from AMPS fixed on polymer particles enhance the chemical and shear stabilities of polymer emulsion and also reduce the amount of surfactants leaching out of paint film.
AMPS improves the thermal and mechanical properties of adhesives, and increases the adhesive strength of pressure-sensitive adhesive formulations.

Detergents: Enhances the washing performance of surfactants by binding multivalent cations and reducing dirt attachment.

Personal care: Strong polar and hydrophilic properties introduced to a high molecular weight AMPS homopolymer are exploited as a very efficient lubricant characteristic for skin care.

Medical hydrogel: High water-absorbing and swelling capacity when AMPS is introduced to a hydrogel are keys to medical applications.

Hydrogel with AMPS showed uniform conductivity, low electrical impedance, cohesive strength, appropriate skin adhesion, and biocompatible and capable of repeated use and have been used to electrocardiograph (ECG) electrodes, defibrillation electrode, electrosurgical grounding pads, and iontophoretic drug delivery electrodes.
In addition, polymers derived from AMPS are used as the absorbing hydrogel and the tackifier component of wound dressings.
Is used due to its high water absorption and retention capability as a monomer in superabsorbents e. g. for baby diapers.

Such polymers with low molecular weights cannot only inhibit calcium, magnesium, and silica scale in cooling towers and boilers, but also help corrosion control by dispersing iron oxide.
When high molecular weight polymers are used, they can be used to precipitate solids in the treatment of industrial effluent stream.
Crop protection: increases in dissolved and nanoparticulate polymer formulations bioavailability of pesticides in aqueous-organic formulations.
Membranes: AMPS increases water flow, retention and fouling resistance of asymmetric ultrafiltration and microfiltration membranes and is being studied as an anionic component in polymer fuel cell membranes.
Construction applications: Superplasticizers with AMPS are used to reduce water in concrete formulations. Benefits of these additives include improved strength, improved workability, improved durability of cement mixtures.

Redispersible polymer powder, when AMPS is introduced, in cement mixtures control air pore content and prevent agglomeration of powders during the spray-drying process from the powder manufacturing and storage.
Coating formulations with AMPS-containing polymers prevent calcium ions from being formed as lime on concrete surface and improve the appearance and durability of coating

Acrylamide/2-acrylamido-2-methylpropane sulfonic acid sodium salt-based hydrogels: synthesis and characterization
AMPS

In recent years, hydrogels derived from acrylamide (AAm) have received considerable attention for use as specific sorbents and as support carriers in biomedical engineering.
AAm-based hydrogels are prepared mainly by freeradical crosslinking copolymerization of the AAm monomer with the N,N0 -methylenebis(acrylamide) (BAAm) crosslinker.

In order to increase their swelling capacity, an ionic comonomer is also included in the monomer mixture.

The swelling behavior of polymer gels is known to depend on their network structure whereas the latter is closely related to the conditions under which the polymer gels are formed.
Thus, the understanding of the formation mechanism of hydrogels is of great interest in predicting their physical properties.

Although extensive work has been reported in the literature for the swelling and collapse phenomena in AAm-based hydrogels, only a few were concerned with their formation mechanism.
The aim of this work was to investigate the formation process of AAm-based hydrogels by free-radical crosslinking copolymerization.
For this investigation, we selected 2-acrylamido-2-methylpropane sulfonic acid sodium salt (AMPS) as the ionic comonomer of AAm.

AMPS has received attention in the last few years due to its strongly ionizable sulfonate group; AMPS dissociates completely in the overall pH range, and therefore, the hydrogels derived from AMPS exhibit pH independent swelling behavior.
AMPS was shown that the linear polymers with sulfonate groups derived from AMPS exhibit extensive coil expansion in aqueous solutions; even in a 5 M NaCl solution, the expansion of polymer coils due to charge repulsion cannot be totally screened.
Liu et al. investigated the swelling properties of hydrogels derived from AMPS and N,N-dimethylacrylamide (DMAA) and observed a similar behavior.

Tong and Liu observed a constant swelling capacity of AMPS/DMAA hydrogels in the whole pH range and concluded that the AMPS content of the hydrogel corresponds to its charge density.
Their calculation results showed a large discrepancy between the measured swelling data in water and that predicted by the Flory–Rehner theory of swelling equilibrium.
We investigated the swelling behavior of AAm/AMPS hydrogels in water and in aqueous salt solution.
In contrast to Tong and Liu, we observed a good agreement between the Flory–Rehner theory and experiment.

All the studies mentioned above only dealt with the physical properties of the final hydrogels without considering their formation history.
The present work focuses on the relationships between the formation mechanism and the swelling behavior of AAm/AMPS hydrogels.
In this study,a series of hydrogels was prepared in the presence of BAAm as the crosslinker such that the crosslinker ratio (mole ratio of crosslinker to monomer) and the initial monomer concentration were fixed, while the AMPS content in the monomer mixture was varied from 0 to 100 mol%.
We have investigated the comonomer reactivities, time-conversion profiles, the growth rate and the swelling properties of the hydrogels depending on the initial monomer composition.
