摘要：Fabrication and electrical properties of barium titanate/polydimethylsiloxane/carbon nanotube composites for self-powered materials were reported. In this research, the effect of surface treatment on electrical properties has been studied. The surface of barium titanate（BT） nanoparticles was chemically modified by hydrogen peroxide（H2O2） to create hydroxyl groups, and the surface of carbon nanotubes（CNT） was modified by nitric acid to introduce carboxyl groups. The measured electrical outputs of the surface hydroxylated BT based nanocomposites under periodic knocking showed higher output voltage than original composite. It is revealed that the strong interaction of hydrogen bond between modified BT and CNT is the important factor for the improved electrical properties.
