摘要
采用有机-无机同步聚合法使酚醛树脂(PF)的单体聚合和正硅酸乙酯(TEOS)的水解缩合反应同步进行制备了水溶性PF/SiO2杂化材料。红外光谱分析和扫描电镜分析表明,在有机-无机同步聚合过程中,SiO2粒子与PF基体间形成有机、无机互穿网络结构,并且实现了有机、无机两相间的强界面结合。采用差示扫描量热仪对杂化材料的固化行为进行了研究。热失重分析表明,杂化材料的耐热性能明显提高,大大拓宽了其应用范围。
The water soluble phenolic resin/SiO2 hybrid materials are prepared by organic-morgamc copolymerlzatlon technique that the polymerization of phenolic resin monomers and the hydrolysis polycondensation reaction of tetraethyl orthosilicate process at the same time. FTIR and SEM analyses indicate that SiO2 particles and phenolic resin matrix form organic-inorganic interpenetrating network, and there are strong combinations between organic-inorganic phases. DSC is applied to study the curing behavior of hybrid materials. TGA analysis indicates that the thermal stability of hybrid materials is improved after adding SiO2 particles into phenolic resin matrix.
