Abstract
Nanoalumina-filled poly(benzoxazine ester) composite films were prepared by addition of various nanoalumina contents into poly(benzoxazine-ester) derived from bisphenol-A/3,5 dimethylaniline-based benzoxazine (BA-35x) and 3,3′,4,4′-benzophenonetetracarboxylic dianhydride (BTDA). Chemical characteristics, thermomechanical properties, thermal stability, and thermal diffusivity of the composite films were investigated. The obtained results, i.e., degradation temperatures, glass transition temperatures, and thermal diffusivity properties of the composite films were enhanced with nanoalumina content. The composite film filled with 15 wt% of nanoalumina showed significant improvement in degradation temperature and solid residue, i.e., 404 °C and 62 %. The glass transition temperature of the composite film was increased with increasing nanoalumina content and exhibited a maximum value of 310 °C at 15 wt% of nanoalumina. IR spectra showed complete curing reaction and all characteristic peaks of the ester linkage and nanoalumina particles were observed in the poly(benzoxazine-ester) composite film. Based on the findings in this work, the poly(benzoxazine-ester) composite films can potentially be used in the case where a high stiffness and high thermal properties are required, i.e., coating film and polymeric matrix for fibre-reinforced composites.
