Preparation and characterization of para-aramid conductive paper
Para-aramid base paper was prepared by using short-cut para-aramid fiber and its conductive finishing was carried out.The test results showed that the molecular structure of hot-pressed para-aramid base paper was maintained with para-aramid fibers and the crystallinity was reduced to 57.37%.At 700℃,the mass retention rate of hot-pressed para-aramid base paper was about 35%.Compared with the short-cut para-aramid fibers,the thermal properties and crystallinity were lower,but still at a higher level.When the proportion of graphene oxide in the conductive finishing agent was 8%,the surface resistance of para-aramid conductive papers was about 200 Ω/m2.It was verified that it was the feasibility of preparing para-aramid conductive papers with both thermal and electrical properties through this process.
