石墨烯微片/氰酸酯多功能树脂基体研究
|
摘要
为了制备集导电、导热、低热膨胀系数于一体的功能型氰酸酯树脂,采用石墨烯微片(KNG-150)改性氰酸酯树脂,对改性前后的粘度、电导率、热导率、热膨胀系数、力学性能以及断面破坏形貌进行分析,并通过理论计算和试验测试综合研究了石墨烯微片对氰酸酯热膨胀系数的影响。结果表明:石墨烯微片可以综合提高氰酸酯的导电、导热性能,并降低氰酸酯的热膨胀系数,但是石墨烯微片的加入会造成氰酸酯粘度增大,同时降低其力学性能。
In order to prepare functional cyanate resin which integrates conductivity, thermal conductivity and a low thermal expansion coefficient, a graphene nanoplatelets(KNG-150) was chosen to modify the cyanate ester resin. The viscosity, conductivity, coefficient of thermal expansion, mechanical property, and fracture surfaces before and after modification were analyzed. The effects of graphene nanoplatelets on the thermal expansion coefficient of cyanate esters were studied by theoretical calculations and experimental tests. The results show that graphene nanoplatelets can improve the electrical and thermal conductivity of cyanate ester and reduce the thermal expansion coefficient of cyanate ester. However, the addition of graphene nanoplatelets can increase the viscosity of cyanate ester and decrease the mechanical properties.
