In this paper, hollow glass microspheres (HGMs) were surface treated using a silane coupling agent to coat the surface with an amine functional group. Modified and unmodified HGM filled polycarbonate (PC)/acrylonitrile butadiene styrene (ABS) (70/30 wt.%) composites were prepared using a twin-screw extruder and then injection moulding. By means of FTIR spectroscopy, it was found that the modified HGMs containing the amine group formed an aminolysis compound with the PC phase. Scratch studies were performed at low load to avoid fracturing the composites during the test so that deformation of the material only happened in order to understand the influence of HGMs and modified HGM on the scratch behaviour of the composites. The silane modified HGM filled PC70/ABS30 composites exhibited improvement in scratch behaviour as compared to the composites containing unmodified HGMs. The 5 wt.% HGM-NH2 filled PC70/ABS30 composites demonstrate good improvement in scratch resistance as they attained the the highest values of scratch force, coefficient of friction, and scratch hardness among all the compositions of composites.
