MCM-41表面改性及MCM-41/环氧树脂复合材料陷阱特性
MCM-41 Surface Modification and Trap Characteristic of MCM-41/EP Composites
摘要
Abstract
In this paper, the MCM-41 was surface modified by the silane coupling agent KH550 before the preparation of MCM-41/EP nano-composite. Moreover, the thermogravimetric analysis, Fourier transform infrared spectroscopy, small angle X-ray diffraction and N2adsorption-desorption isotherms were used to characterize the surface structure of MCM-41 before and after surface modification. The in-situ polymerization was employed to prepare the MCM-41/EP Nano-composite with different percentages of MCM-41. Then, the glass transition temperature of MCM-41/EP composite was measured by using the dynamic mechanical analyzer. The results showed that the glass transition temperature of MCM-41/EP composite increased with the increase of MCM-41 percentage.Finally, the trap parameter of the composite was measured by the thermally stimulated depolarization current. It was shown that, with the increase of MCM-41, the trap depth became shallow, and the quantity of trapped charge decreased significantly.关键词
