Abstract:
Graphene oxide (GO) is a chemical oxidized of graphite carbon material, including hydroxyl,carboxyl, carbonyls or epoxides functional groups [1, 2]. The presence of these groups on theGO surface provides reactive sites for the immobilization of electrical insulating materials(e.g./ SiO2, Al2O3, SiC, Al(OH)3 or nitrides) [3]. Herein, we report a simple synthesis procedureof GO from industrial grade graphite at room temperature. SiO2 decorated with reducedGO (SiO2@rGO) as thermally conductive electrically insulating composite was synthesized(Fig. 1). The prepared composite can act as a base material for the future various applicationslike electronic packaging, thermal management and the perfect functional additive for polymercomposite preparation. The FTIR spectrum index bands of prepared GO and SiO2@rGOwere appeared at about 1725 and 1064 cm-1 respectively. SEM images and EDS analyseswere employed to verification of surface morphology of product and chemical fluctuations ofSiO2 respectively.(Project code 3/47733)
