In this study, nano-sized Al2O3/BA-35x and PMDA based copolymers with different Al2O3 contents were prepared. The thermomechanical properties, thermal stability and thermal diffusivity of the BA-35x/PMDA copolymer can be improved by addition of nano-sized Al2O3. Storage modulus of 4.13 GPa, glass transition temperature of 320oC and thermal degradation of 394�C were obtained for the composite film with 10 wt% of Al2O3, while thermal diffusivity of the composite significant increased to approximately 37.5�10-8 m2/s as the Al2O3 content reached 25 wt%. Considering the high mechanical property, thermal stability and thermal diffusivity of the Al2O3-filled BA-35x/PMDA composite films, they can potentially be used in the case where a high stiffness and high thermal properties are required.
