摘要

考察了纳米SiO2/PMMA复合体系的耐磨损性.采用原位本体聚合方法制备纳米SiO2/PMMA复合板

使用扫描电镜和光学显微镜对纳米SiO2及其复合物进行观察

采用砝码质量法测试复合物的耐磨损性.电镜观察结果表明:纳米SiO2较为均匀地分散在PMMA基体中

并被PMMA所包覆

包覆物的粒径介于30~100 nm之间.耐磨损性测试结果表明:纳米SiO2的加入可提高PMMA复合物的耐磨损性和耐划痕性;当纳米SiO2用量为1.0%时

复合物的耐磨损性能提升39.7%.

Abstract

Nanosized SiO2/PMMA composites were in-situ prepared

and wear resistance of the composites was investigated in this paper.SEM and OM techniques were used to characterize and examine the nanosized SiO2 and its composites.Wear resistance of the composites was evaluated using the set of weights.The characterization and examination results showed that nanosized SiO2 were well dispersed in PMMA

and were wrapped in the PMMA;the sizes of the wrapped particles were in the range of 30～100 nm.The wear resistance resu...
