Abstract
本发明涉及环氧树脂改性技术领域，尤其涉及一种低介电改性环氧树脂及其制备方法和应用。本发明将环氧树脂、固化剂、笼型聚倍半硅氧烷‑八环氧基和催化剂混合，得到树脂混合体系，对树脂混合体系进行固化，得到低介电改性环氧树脂。本发明利用笼型聚倍半硅氧烷‑八环氧基空间结构与基团效应，在酸酐作固化剂后与双酚A型环氧树脂同时进行环氧基团开环交联固化，获得杂化体系，促使改性环氧树脂的整体介电性能提高。测试结果表明，当POSS‑101质量占比为10％时，改性的环氧树脂在1GHz条件下表现出较低的介电常数约2.87，介电损耗角正切值可以达到(0.02)。整个改性方案工艺步骤简单，操作可行性高，易于生产实用化。
