硅氧烷改性苯并噁嗪研究进展

Progress of Siloxane Modified Benzoxazine

苯并噁嗪树脂因其优异的性能得到广泛关注,但同时存在固化温度较高、固化时间较长、脆性大等问题研究人员对此进行了一系列改性研究。硅氧烷具有柔韧性好、表面张力低等特点,利用硅氧烷改性苯并噁嗪已成为相关研究的热点方向。本文主要简述了近年来硅氧烷改性苯并噁嗪的合成、性能及应用的新进展,并对其新研究方向进行了展望。

Benzoxazine resin has attracted widespread attention due to its excellent properties, but it also has problems such as high curing temperature, long curing time and high brittleness. Researchers have conducted a series of modification studies on this issue. Siloxanes have the characteristics of good flexibility and low surface tension, and the use of siloxane modified benzoxazines has become a hot research direction. This article mainly describes the new progress in the synthesis, properties, and applications of siloxane modified benzoxazines in recent years, and looks forward to their new research directions.
