有机-无机Nano-SiO_2/DCPDCE杂化材料的性能

Properties of Organic-Inorganic Nano-SiO_2/Dicyclopentandiene Cyanate Ester Resin Hybrid Materials

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。

To resolve the problem of ordinary nano-SiO2 easy-agglomeration in the dicyclopentandiene cyanate ester（DCPDCE） resin system, DCPDCE, was modified u This article discussed the properties of organic-inorgani cal properties. The result showed that, compared with DCPDCE. When the content of organic-inorganic nano-SiO2 is 3.0wt%, the total properties of hybrid materials is the best.
