摘要
Abstract
In this study,the bipolar plate composites were prepared by using a compression-molding technology using nat-ural flake graphite(NG)as conductive aggregate,phenolic resin(PF)and unsaturated polyester resin(UPR)as bind-ers.The effects of the mass ratio of PF to UPR,resin content,and molding conditions on the electrical conductivity and bending strength of the composites were studied by differential scanning calorimetry.The results indicated that the bipo-lar plate composites obtained an electrical conductivity of 336.1 S/cm and bending strength of 46.5 MPa at a resin con-tent of 20 wt%with a NG/PF/UPR mass ratio of 6∶1,a pressing temperature of 100 ºC,a molding pressure of 30 MPa,a molding temperature of 180 ºC,and a molding time of 2 h.Compared to the NG/PF bipolar plate composite under the same processing conditions,the NG/PF/UPR bipolar plate composites exhibited an increase in electrical con-ductivity by 134.9%and in bending strength by 21.2%.关键词
