Synthesize of Poly (acrylamide-co-itaconic/TiO2) Nanocomposite for Ce(III) Sorption from Monazite Leachate

Montmorillonite Nanocomposite Hydrogel Based on Poly(acrylicacid-co-acrylamide): Polymer Carrier for Controlled Release Systems

In this paper, the synthesis of new montmorillonite nanocomposite hydrogel (MMTNH) based on poly (acrylic acid-co-acrylamide) grafted onto starch, is described. Montmorillonite (MMT) as nanometer base, acrylic acid (AA) and acrylamide (AAm) as monomers, ammonium persulfate (APS) as an initiator, N,N-methylenebisacrylamide (MBA) as a crosslinker and starch as a biocompatible polymer were pre...

Swelling Characterization of Nanocomposite Hydrogels of Poly (acrylamide-N-vinylimidazole)

In this study, a hydrogel composed of acrylamide (AAm) with N-vinylimidazole (NVI) as co-monomer, with a cross-linker such as N, N` Methylenebisacrylamide and potassium peroxodisulfate as an initiator solution was prepared. Poly (AAm/NVI) hydrogels were synthesized by free radical solution polymerization. Swelling experiments were performed in water at 25°C, gravimetrically. Here, it was of...

Magnetic Poly-(Acrylonitrile-Co-Acrylamide) Microparticles for Immobilization of Trypsin

Well-shaped spherical magnetic microspheres were prepared using a synthetic polymer of poly-(acrylonitrile-co-acrylamide). Their size varied from 100 up to 1000 μm proportionally to the flow rate of the polymer solution and their density was from 1030 to 1045 kg.m, depending on the magnetite content. Trypsin (EC 3.4.21.4) was chosen as model enzyme and immobilized on the acyl azide derivatives ...

Experimental Investigation of Mechanical and Thermal Properties of Silica Nanoparticle-Reinforced Poly(acrylamide) Nanocomposite Hydrogels

Current studies investigating properties of nanoparticle-reinforced polymers have shown that nanocomposites often exhibit improved properties compared to neat polymers. However, over two decades of research, using both experimental studies and modeling analyses, has not fully elucidated the mechanistic underpinnings behind these enhancements. Moreover, few studies have focused on developing an ...
