Flame retardants, such as inorganic fillers or halogenated resins, are incorporated into composites either as additives or reactive materials. In order to improve processability and mechanical properties, as well as reduce smoke toxicity, a method is being developed to introduce highly effective, inexpensive flame retardant materials into thermoset resins. Superabsorbent polymers (SAP) can be l...

Tel.: +86-451-8219-1693 An antimicrobial superabsorbent was prepared by grafting polyacrylic acid on tara gum and adding chitosan quaternary ammonium salt (2-NHydroxypropyl-3-trimethylammonium chloride chitosan, HTCC). The effect of the amount of HTCC on swelling ratio of the product was investigated. The product was characterized by Fourier transform infrared (FTIR) spectroscopy, scanning elec...

OBJECTIVE To demonstrate the binding and inactivation action of a superabsorbent dressing on proteolytic enzymes MMP-2, MMP-9 and collagenase using an established methodology. METHOD An in vitro assay of MMP binding and collagenase inactivation has been conducted using the superabsorbent wound dressing (Eclypse; Advancis Medical UK). Dressings in this category, and other absorbents, have been...

Synthetic polymer was exploited as water-superabsorbent hydrogel and helped to conserve water in the agricultural soil. The hydrogel polymers were synthesized the carboxymethyl cellulose (CMC) and starch in addition to SiO2 nanoparticles. Superabsorbent hydrogel polymer having 35% water retention ability was analyzed with three replicates. Hydrogel increased the water restoration capability of ...

A series of novel guar gum-g-poly(sodium acrylate-co-styrene)/muscovite (GG-g-P(NaA-co-St)/MVT) superabsorbent composites were prepared by free-radical grafting copolymerization of natural guar gum (GG), partially neutralized acrylic acid (NaA), styrene (St) and muscovite (MVT) using ammonium persulfate (APS) as the initiator and N,N-methylene-bis-acrylamide (MBA) as the crosslinker. Optical ab...

New superabsorbent hydrogels were synthesized through free radical graft copolymerization of partially neutralized acrylic acid (AA) and 2-acrylamido-2-methylpropanesulfonic acid (AMPS) onto carboxymethyl cellulose (CMC) backbones. The structure and morphology of the synthesized superabsorbent hydrogels were characterized by Fourier transform infrared spectroscopy and scanning electron microsco...

Abstract The production of environmentally friendly SAP using biodegradable natural resources such as chitosan was synthesized for water saving and controlled-released fertilizer. Chitosan-g-poly(acrylamide)/attapulgite superabsorbent composites (CTS) were created by crosslinking N , '-methylene-bis-acrylamide (MBA) with (Ch), acrylamide, attapulgite (ATP) initiating the reaction potassium pers...
