“…Moreover, the higher SO 3 Na content in the copolymer networks with non‐ionic monomers increases the electrostatic interaction with MB. It is also expected that the amido groups of VP, MBA and Na‐AMPS form hydrogen bonds between water molecules coordinated to cationic MB dye and sulfonate groups forming ion−dipole interactions with the cationic site of MB . Furthermore, the adsorption capacities of the cryogels increased with increasing pH up to pH 7 and then became constant (Fig.…”

Magnetite cryogel composites as macroporous crosslinked matrices have received wide attention and attract much interest in the water purification and desalination industry. They can be used to produce effective adsorbents with high adsorption rate, capacity and desorption for water pollutants. In this work, the incorporation of magnetite nanoparticles into cryogels by the in situ method is proposed to increase the dispersion of nanoparticles in the gel composites and to produce effective magnetic materials with high adsorption capacities. Ionic sodium‐2‐acrylamido‐2‐methylpropane sulfonate (Na‐AMPS) monomer was selected to prepare cryogels as the homopolymer or copolymers with 2‐hydroxyethyl methacrylate (HEMA) or N‐vinyl pyrrolidone (VP) by the crosslinking polymerization technique in the frozen state. Magnetite nanoparticles were introduced into the cryogel by the in situ co‐precipitation method after introducing iron cations into the cryogel networks. The surface morphologies, crystal structure, magnetite content, thermal stability and magnetic properties were determined for the cryogels and their magnetite composites. The magnetite cryogel composites show significantly enhanced methylene blue dye removal in short times with higher adsorption efficiencies and good regeneration to form an effective adsorbent for water treatment. © 2017 Society of Chemical Industry

“…Firm adsorption of polymer through “anchoring groups” on the clay particles is the foundation for clay/polymer association and is normally explained by three different bonding mechanisms . (a) Ion dipole interactions: the electronegative N and O atoms in the copolymer molecule interact with exchangeable cations between clay lamellae . This includes CONH 2 , CONH, O, SO 3 Na, and (CH 2 CH 2 O).…”

A new comb‐shaped copolymer was synthesized by free radical copolymerization of 2‐acrylamide‐2‐methyl propane sulfonic acid, acrylamide, N‐vinyl‐2‐pyrrolidone, and allyl polyoxyethylene ether (APEG) monomers. The copolymer was evaluated as a filtrate loss reducer in water‐based drilling fluid at 180 °C environment, and found to work well without causing high viscosity effect. Composition of the copolymer was determined by Fourier transform infrared spectroscopy (FTIR), proton nuclear magnetic resonance spectroscopy, and gel permeation chromatography. FTIR, X‐ray diffraction,, and environmental scanning electron microscopy characterizations were used to probe the filtrate loss mechanism of the comb‐shaped copolymer. Thermogravimetry and differential scanning calorimetry results showed that thermal degradation of the copolymer is not obvious before 293.6 °C. The copolymer is found to be superior to its commercially available counterparts for controlling filtrate loss volume and maintaining a steady viscosity after 180 °C aging. Higher content of APEG in the copolymer helps maintain rheological properties of the drilling fluid after aging and reduces filtrate loss volume. The morphology of the copolymer in aqueous solution displays a comb‐shaped 3D structure and shows clear adsorption onto clay particles. The working mechanism for copolymer is that anchoring groups bind the copolymer onto clay particles through different binding mechanisms, while colloidal suspension stability is achieved by steric hindrance and electrostatic repulsion, as well as through PEG segment intercalation into clay lamellae. The copolymer is able to cover and seal the micro‐holes in the mud cake even at high temperature to reduce permeability. © 2017 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 135, 45989.

“…The interaction of AMPSA with silica occurs by adsorption phenomenon through formation of hydrogen bonds between sulfonic acid and amido groups of AMPSA with Si-O linkages. Also another mechanistic model may be cause for better dispersion of filler particles through adsorption of monomer on filler surface and polymerization first starts on the filler surface through adsorbed AMPSA monomer and continues thereafter [27] .…”

“…Moreover, the specific reasons for AMPSA selection lie in the fact that firstly, AMPSA has amido and sulfonic acid contents in the molecule and acts as a surface-active material [26] . Very recently it has been reported that AMPSA is a good candidate as a clay modifier for the preparation of polymer-clay nanocomposites by in-situ free radical polymerization in emulsion [27] .…”

Poly(acrylamide-co-2-acrylamido-2-methyl-1-propanesulfonic acid)/Silica [Poly(AM-co-AMPSA)/SiO 2 ] core-shell composite nanogels with silica as core and hydrophilic polymer with functional groups such as sulfonic acid, amido, as shell were prepared by microemulsion polymerization without surface treatment of silica and upto 5.5 mole% of AMPSA in feed to control the particle size as well as morphology. The synthesized intercalated composites were produced with controllable sizes ranging from 44-77 nm in diameter. The repared sulfonic acid based silica core-shell composite nanogels were characterized by dynamic light scattering, transmission electron microscope, Fourier transform infrared spectrophotometer, thermogravimetric analyzer, differential scanning calorimeter, scanning electron microscope and X-ray diffraction. The encapsulation of functional polymer shell onto the silica particles was driven by the hydrogen-bonding interaction between sulfonic acid and amido groups of AMPSA with Si-O linkages. The onset degradation temperature is increased from 227 C to 262 C in copolymer-silica composites which indicates improved thermal stability. The shifting of glass transition temperature from 194 C to 203 C in copolymeric composite nanogels further confirms the existence of strong interactions of silica filler with copolymer chains. Also the chemical composition of polymeric chains and the affinity of polymer chains and silica influenced the morphology.
