摘　　要：采用超声波分散技术,通过原位聚合方法制备聚甲基丙烯酸甲酯/介孔分子筛SBA-15复合材料(PMMA/SBA-15).通过红外光谱(FT-IR)、X射线衍射(XRD)、扫描电镜(SEM)、热质量分析、物理机械性能等对复合材料的结构和性能进行测试和研究.研究结果表明,与纯PMMA相比,PMMA/介孔分子筛SBA-15复合材料有较好的热稳定性.当SBA-15的质量分数为0.6%时复合材料的拉伸强度和冲击强度分别提高了13.29%和24.20%.In this paper,PMMA/SBA-15 composites were prepared under ultrasonic by the in-situ polymerization.The structure and properties of composites were investigated by FTIR,XRD,SEM and TG.The results showed that composites exhibited better thermal property than pure PMMA.The tensile strength and impact strength of composites could increase by 13.29 % and 24.20 % when content of the SBA-15 was 0.6 %.
