Abstract:
不同含量的聚砜(PSF)对环氧树脂(EP)/PSF共混物相结构有重要影响,通过对反应分相后的样品进行断面观察,发现一定PSF含量时,体系形成了层状结构.这种层状结构通常为3层,包括上下2个外层、由聚砜和环氧树脂的颗粒-基体结构组成,以及1个双连续结构形成的中间层.研究表明,这种层状结构由反应诱导相分离开始之初形成的双连续结构发展而来,由于反应和相分离的进一步发展热塑性树脂富集相的体积分数逐渐减小、以及组分间的动力学不对称而最终形成的.在一定PSF浓度范围内,不同温度固化样品时均得到了这种层状结构.改变固化剂类型,层状结构的形貌受到影响,当固化剂活性较高时,外层变薄中间层增厚.当组分间的相容性较好时,双连续结构甚至不能演化发展到层状结构.
