背景技术
聚酰亚胺(PI)薄膜具有良好的耐高温、高强度、低介电等性能,广泛应用于电子、电气绝缘基材等方面。
随着电子信息技术的飞速发展,电子器件和集成电器的尺寸不断缩小,运行速度越来越快,从而散发出大量的热量。而热量的积聚会严重影响电子器件和电路运行的稳定性,甚至会带来安全隐患。
而常规用作电子电路绝缘基材的聚酰亚胺薄膜,其导热系数一般均低于0.2Wm-1K-1,所制备器件散热效果不理想,长期处于高温状态,也会影响聚酰亚胺薄膜的尺寸稳定性。

本发明提出的一种高温尺寸稳定导热聚酰亚胺薄膜的制备方法,包括如下步骤:在惰性气体氛围中,向芳香型二胺溶液中加入填料混匀,然后加入芳香型二酐,进行反应,然后加入八(氨基苯基三氧硅烷)溶液,继续反应得到中间物料;取中间物料脱泡并涂布于基板表面,烘干,亚胺化,脱膜得到高温尺寸稳定导热聚酰亚胺薄膜,其中,填料为改性纳米氮化硼和改性纳米二氧化硅。

优选地,烘干温度为110-130℃。
优选地,亚胺化的程序为:于240-260℃保温30-50min,再于320-340℃保温20-40min。
优选地,芳香型二胺、芳香型二酐和八(氨基苯基三氧硅烷)的摩尔比为1:0.9-0.95:0.01-0.02。
