Abstract

Functionalization of montmorillonite clay has been done using 3-aminopropyltriethoxy silane using water as a dispersing medium. Qualitative evidence of the presence or silane attached to the clay surface has been identified using Fourier transform infrared spectroscopy (FT-IR). Increase in silane concentration decreases the adsorbed/intercalated ratio calculated using differential thermogravimetric analysis (DTG). Average d-spacing calculated using X-ray diffraction initially increases with silane concentration and decreases slightly at higher silane concentration. The influence of processing temperature on the silane functionalization of clay has also been investigated and it shows that chemical grafting of silane on the clay surface is observed with increasing processing temperature.

Monmorillonite 클레이를 물을 분산제로 이용하여 3-aminopropyltriethoxy 실란 기능화를 실시하였다. 실란의 그라프트 여부는 FT-IR을 이용하여 정성분석하였다. 실란의 농도가 증가함에 따라 흡착/삽입 비가 감소함을 알 수 있었다. X-ray를 이용하여 평균 d-간격을 측정한 결과 초기에는 실란농도가 증가하다 다소 감소하였다. 기능화 공정온도의 영향을 살펴본 결과 온도가 증가함에 따라 화학적인 그라프트가 증가함을 알 수 있었다.
