Heat treatment effect on the distribution of organic clay in polymer nanocomposites

Abstract

In this paper, the effects of heat treatment temperature on the degree of exfoliation of organic clay under different compatibilizers were tested by using organic clay 93A, high density polyethylene (HDPE) and compatibilizer (PE-g-MA), polyethylene maleic anhydride copolymer (PEMA), maleic anhydride and polyethylene blend (MA/PE). The proportion of organic clay is 5 wt%, HDPE is 90 wt% and compatibilizer is 5 wt%. Temperature ranged from 210oC to 250oC, the position of [001] peak in the sample was determined, FESEM, TGA, FTIR and XRD was used to analyze the influence of temperature on the distribution behavior of clay in polymer system. The results are very significant for the industrial production of clay composite materials.
