纳米SiO2/聚酰亚胺复合薄膜的制备及性能的研究
Study on preparation and performance of nano SiO2/ polyimide compound film
【摘要】 以工业聚酰胺酸为原料,采用直接法制备了纳米SiO2/聚酰亚胺(PI)复合薄膜,通过红外光谱表征了亚胺化前后聚合物结构的变化,利用扫描电子显微镜观察了复合薄膜中SiO2的分散情况,测试了复合薄膜的拉伸强度,研究了纳米SiO2的加入对聚酰亚胺薄膜热稳定性的影响。
【Abstract】 In this paper,nano SiO2/polyimide compound films were prepared by direct method.The changes of PI’s structure were characterized by FT-IR after imidization.Dispersion of SiO2 in films was observed through SEM.Tensile-strength of PI compound films was measured.Influences to thermal stability were studied due to adding nano SiO2 in films.
