氟化石墨烯对聚酰亚胺复合薄膜力学性能的影响
|
摘要
采用溶液共混法制备了聚酰胺酸/氟化石墨烯混合溶液,然后通过流延涂膜和阶梯升温的方法制备了不同含量的聚酰亚胺/氟化石墨烯(PI/FG)复合薄膜,研究了PI/FG复合薄膜的晶相结构和物质结构以及不同掺杂量的氟化石墨烯对PI/FG复合薄膜的力学性能的影响.结果表明,制备了聚酰亚胺/氟化石墨烯复合薄膜,且氟化石墨烯含量越高聚酰亚胺的力学性能越好,当氟化石墨烯质量分数为1.0%时,PI/FG复合薄膜的拉伸强度、弹性模量、断裂伸长率可分别高达237.26 MPa、4.23 GPa和5.58%.
In the paper,the polyimide/fluorinated graphene(PI/FG)mixed solution were prepared by solution blending method,and the PI/FG composite films were prepared by curtain coating method and were raised the temperature in steps with different mass fraction. The crystal phase,material structure and the mechanical properties were studied.The results showed:the PI/FG composite films were successfully prepared. The mechanical properties could be improved by adding appropriate fluorinated graphene. The tensile strength,elastic modulus and elongation were at break of PI/FG films up to 237.26 MPa,4.23 GPa and 5.58% repectively when the FG content was 1.0%.
