Preparation And Characterizations Of Highly Filled Graphene-Polybenzoxazine Composites, R Plengudomkit, M Okhawilai, S Rimdusit

Journal of Metals, Materials and Minerals

In recent years, graphene has been extensively utilized in electronic applications due to its superior electrical conductivity, high thermal conductivity and excellent mechanical properties [1, 2]. This research emphasized on the development of graphene (xGnP Grade H, XG Science, USA) filled composites based on polybenzoxazine particularly at high graphene loading (0-60wt%) [3, 4]. It was found that the density of the obtained composites was linearly increased with graphene content and the values were determined to be 1.185-1.637 g/cm3 which followed the rule of mixture suggesting negligible void in the composites samples. Mechanical and thermal properties of the graphene filled polybenzoxazine …
