| Abstract: | Using carbon nanotubes(CNTs) after Fenton/UV treatments at different pH as a reinforcement,and a phenol formaldehyde resin/graphite(PF/G) composite as matrix,a new composite for a bipolar plate was formed by hot-pressing.The effect of different pH in Fenton reagents on the CNTs and properties of CNTs reinforced PF/G composite were investigated.The functional groups on the surface of CNTs were investigated by FTIR,and the phase analysis of CNTs was investigated by X-ray diffraction analysis(XRD).The results show: it is introduced to a large quantity of hydroxyl groups and few carboxyl groups on the sidewalls of the CNTs when pH is 3 in Fenton reagents;the properties(bending strength and conductivity) of composite increase firstly and then decrease with the increasing of pH;the optimum pH is 3 for the properties of composite,which bending strength and conductivity are 67.3MPa and 175.6s/cm respectively. |
