Polymer matrices add carbon nanotubes have significantly improved mechanical and electrical properties at very low carbon nanotube loading. That mechanical and electrical properties of aligned composites are better than those of random ones has been demonstrated in past studies. The non-conductive barriers of surface contaminants and weakly bound polymer layers will deform on the surface of composite resulted from the effects of micro gravity and oxidization. Addition of the adaptive plasma modification makes improvement in the surface properties of the composites is necessary. In this study, we actively align and network multiwall carbon nanotubes (MWCNTs) in a polymer matrix, then adopt O2/CF4radio frequency (RF) plasma to modify the surface of polymeric composite. MWCNTs were aligned using an AC electric field to elicit dipolar interactions among the nanotubes in a viscous matrix following immobilization by curing under continuous application of an anisotropic electric field, and the barriers of surface contaminants and weakly bound polymer layers can be reduced to the smallest degree or eliminated by RF plasma modification. Consequently, the MWCNTs polymeric composite amplify the flexural modulus, wear resistance, and electrical conductivity in the reality.

Properties Of Composites

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.
