STUDY ON MULTIFUNCTIONAL GNPs/CYANATE ESTER RESIN MATRIX

Abstract

Abstract: 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.

Key words: graphene nanoplatelets, cyanate ester, thermal expansion coefficient, thermal conductivity, functional composites
