Effect of Multiwall Carbon Nano Tubes (MWCNT) on Mechanical and Electrical Properties of PP/C Composites as Alternative Materials for Bipolar Plate Fuel Cell

摘要

The properties of polypropylene can be improved by addition of multiwall carbon nanotube (MWCNT). This research focuses on material design of composite based on polymer matrix and carbon including MWCNT to improve mechanical and electrical properties of composites according to the requirement for bipolar plate material. It is found that the effect of small addition of MWCNT and Cu have been increasing electrical conductivity up to 15.62 S/cm while tensile and flexural strengths increase to 14.97 MPa and 31.78 MPa respectively.
