Preparation and Characterization of Organic Pillared Hydromica
摘要
Abstract
Hydromica was obtained with vermiculite layer at edge area and mica layer in central area by exchanging Ba2+and K+in biotite. The organic pillared hydromica was produced by stearyl trimethyl ammonium chloride pillaring hydromica. The powder samples were characterized by X-ray diffraction measurements and Fourier transform infrared spectroscopy,the effects of STA+ on basal spacing of hydromica and the arrangement of STA+ in the interlayer were explored. The results show that all the vermiculite layers and some mica layers were pillared by STA+in hydromica,and the basal spacing of pillaring layer is 2.8 nm. Intercalated STA+formed a monolayer structure with angle of 45°.关键词
