摘要
采用原位聚合法制备加成型液体硅橡胶（ALSR）／有机蒙脱士（OMMT）纳米复合材料，并对其结构和性能进行研究。结果表明，经改性的OMMT的层间距是钠基蒙脱士（Na-MMT）的1．4～3．6倍；OMMT质量分数为0．01时，ALSR／OMMT纳米复合材料的物理性能和热稳定性较好，OMMT的剥离程度较大，基本以纳米尺度的剥离片层分散在ALSR基体中。
The addition-type liquid silicone rubber （ALSR）/organo-montmorillonite （OMMT） nano-composites were prepared by in situ polymerization, and their structure and properties were investigated. The results showed that the distance between the layers of OMMT was 1.4-3.6 times as that of Na-MMT; and when 1% OMMT by mass was used, an ALSR/OMMT nano-composite with better physical properties and thermal stability was obtained; in the ALSR/OMMT nano-composite more OMMT was exfoliated,and most of OMMT was dispersed in exfoliated nano dimension layers in ALSR.
