Preparation and Characterization of Mesoporous Silica/ Novolac Type Phenol-Formaldehyde Resin Hybrid Materials

利用水热法合成介孔分子筛（SBA-15）,选择KH560对其表面进行修饰后采用原位聚合的方法制备了介孔分子筛/线性酚醛树脂（SBA-15/PF）有机无机杂化材料。通过傅立叶红外光谱（FT-IR）、X射线衍射（XRD）、N2吸附和热失重分析（TGA）等表征手段对杂化材料的制备过程进行跟踪研究。结果表明,KH-560已嫁接到SBA-15的内外表面,线性酚醛树脂分布于介孔分子筛孔道内外,并与SBA-15存在键接作用,形成有机无机互穿网络结构;表面修饰过程对SBA-15有序结构影响较小,而原位聚合会破坏介孔分子筛部分有序结构。

Mesoporous silica/novolac type phenol-formaldehyde resin hybrid materials were prepared via in situ polymerization at the silica SBA-15,which was treated with γ-glycidyl oxypropyl trimethoxysilane（KH560） as coupling agent.SBA-15,SBA-15-KH560 and E-SBA-15/PF were characterized and analyzed with X-ray diffraction（XRD）,N2 adsorption isotherm,Fourier transform infrared spectroscopic（FT-IR） and thermogravimetric analysis（TGA） respectively.The results indicate that KH560 was chemically grafted onto SBA-15,and PF distributed into the inner and outer path of the SBA-15.An interpenetrating network of organic-inorganic was formed in this hybrid materials.The regular structure of SBA-15 was little influenced with KH560,but it was greatly modified viain situ polymertization.
