Preparation and Characterization of Poly(acrylamide/maleic acid)-based hydrogels Composites

Poli(akrilamid-maleik asit) temelli hidrojel kompozitlerin Hazırlanması ve Karakterizasyonu

The principle aim of this investigation was the preparation and characterization of the composites formed from Bentonite (B) and Zeolite (Z) minerals, and polyacrylamide-co-maleic acid (PAA-MA) hydrogel polymers. The procedures used in obtaining the polymers were also applied in preparation of the composites by direct polymerization of the monomers of interests dissolved in the suspension of B or Z. The prepared PAA-MA and the composites were characterized with the data and analysis results obtained from FT-IR, TGA, SEM, BET-porosity and Zero Point of Surface Charge (PZC). The results of FT-IR, TGA, SEM, BET-porosity and PZC analysis presented certain evidences for the formation of composites, it was impressed that the composites were the mixtures composed of two phases composing of organic (PAA-MA) and inorganic (B or Z) phases rather than the formation of polymer/ mineral hybrid.
