To resolve the problem of ordinary nano鄄SiO2 easy鄄agglomeration in the dicyclopentandiene cyanate es鄄
ter(DCPDCE) resin system,DCPDCE,was modified utilizing organic鄄inorganic nano鄄SiO2 prepared by sol鄄gel process.
This article discussed the properties of organic鄄inorganic nano鄄SiO2 / DCPDCE,such as dielectric properties and mechani鄄
cal properties. The result showed that,compared with ordinary SiO2,organic鄄inorganic SiO2 can be well鄄dispersed in
DCPDCE. When the content of organic鄄inorganic nano鄄SiO2 is 3. 0wt%,the total properties of hybrid materials is the
best.
