| 摘 要： | 为解决传统商用nano-SiO2粒子在双环戊二烯型氰酸酯(DCPDCE)树脂基体中容易团聚的问题,利用Sol-Gel法制备的有机-无机nano-SiO2为填料对DCPDCED进行改性。研究了有机-无机nano-SiO2含量对nano-SiO2/DCPDCE杂化材料力学性能、介电常数、介电损耗因子的影响。结果表明:有机-无机nano-SiO2较商用nano-SiO2在DCPDCE中分散更优;当有机-无机纳米SiO2含量为3.0wt%时,杂化材料的综合性能最优。

| Abstract: | To resolve the problem of ordinary nano-SiO2 easy-agglomeration in the dicyclopentandiene cyanate ester(DCPDCE) resin system,DCPDCE,was modified utilizing organic-inorganic nano-SiO2 prepared by sol-gel process.This article discussed the properties of organic-inorganic nano-SiO2/DCPDCE,such as dielectric properties and mechanical properties.The result showed that,compared with ordinary SiO2,organic-inorganic SiO2 can be well-dispersed in DCPDCE.When the content of organic-inorganic nano-SiO2 is 3.0wt%,the total properties of hybrid materials is the best. |
