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.

Poli akrilamid-maleik asit temelli hidrojel kompozitlerin Hazırlanması ve Karakterizasyonu

Öz

B u araştırmanın temel amacı Bentonit B ve Zeolit Z minerallerinin hidrojel polimer olan Poliakrilamidko-maleik asit PAA-MA ile oluşturduğu kompozitini hazırlamak ve karakterize etmektir. Polimerlerin elde edilmesinde kullanılan yöntem, kompozitlerin hazırlanmasında da kullanılmış ve B veya Z içeren süspansiyon ortamında bulunan ilgili monomerlere doğrudan polimerleştirme işlemi uygulanmıştır. Hazırlanan PAA-MA ve kompozitlerin yapısal karakterizasyonunda FT-IR, TGA, SEM, BET-Gözeneklilik ve sıfır yüzey yük noktası PZC ile ilgili veri ve analiz sonuçları kullanılmıştır. FT-IR, XRD, TGA, SEM, BET-gözeneklilik ve PZC analiz sonuçları kompozit oluşumu ile ilgili kesin kanıtlar sunmuş, yapıların polimer/mineral hibrit oluşumundan çok biri organik PAA-MA ve diğeri inorganik özellikteki B veya Z iki faz içeren bir karışım olduğu kanısına varılmıştır
