A Unique Approach To Prepare Poly (Acrylamide –Co-Itaconic Acid) /Graphite Composite Polymer For Electrical Conducting
نویسندگان
چکیده
In this work a pH-sensitive poly(acrylamide-co-itaconic acid)/ graphite composite hydrogel is prepared by free radical initiated polymerization of monomers acrylamide(Am) and itaconic acid(IA) in the presence of settled graphite(Gt) particles using N,N’-methylene bisacrylamide(MB) as cross linker in aqueous medium. The SEM analysis revealed almost uniform distribution of grafite particles within the polymer matrix.For the same amount of graphite, the conductivity of hydrogel composite was observed to increase and later on decrease with amount of cross linker (MB) and

Investigation of Antibacterial Properties of Silver Nanoparticle-loaded Poly (acrylamide-co-itaconic acid)-Grafted Cotton Fabric
Cotton fabric was grafted with a poly (acrylamide-co-itaconic acid) co-polymer via ceric ammonium nitrate (CAN) induced graft co-polymerization in an aqueous medium. The grafted cotton fabric was loaded with Ag nanoparticles by entrapment of Ag+ ions into a grafted polymer network, followed by borohydride reduction. The resulting Ag nanoparticle-loaded grafted fabric was characterized by Fourie...
متن کاملPreparation of silver-poly(acrylamide-co-methacrylic acid) composite microspheres with patterned surface structures
Acrylamide (AM) and methacrylic acid (MAA) copolymer microgels were prepared by a reverse suspension polymerization technique. The microgels were used as templates for the preparation of silver-poly(acrylamide-co-methacrylic acid) [Ag-P(AM-co-MAA)] composite microspheres. The surface structures of the microspheres prepared in this way are characterized by zigzag-like structures. It was found th...

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...

A novel pH-responsive superabsorbent hydrogel based on gelatin was prepared through crosslinking copolymerization of poly (acrylic acid) and poly (itaconic acid). The copolymerization conditions including monomers, initiator, gelatin and crosslinker concentration, reaction temperature, and neutralization percent were systematically optimized to achieve a hydrogel with swelling capacity as high ...

Soap-free emulsion polymerization (SFEP) of methyl methacrylate, butyl acrylate was conducted in water/methanol media with sodium salts of four different acidic comonomers, namely styrene sulfonic acid (NaSS), 2-acrylamide-2-methyl-1-propane sulfonic acid (NaAmps), acrylic acid (NaAA), and itaconic acid (Na2ita). It was found that the introduction of methanol as co-solvent (35 wt%) to the mediu...
