| Abstract:Aramid fiber based paper materials have been widely used in electronic communication, military industry, aerospace and other fields owing to the excellent heat resistance, good electrical insulation capability and mechanical properties. However, the low thermal conductivity of aramid fiber largely limited the application of aramid fiber based paper materials in electronic devices, power systems, etc. Accordingly, an efficient work to improve the thermal conductivity of aramid fiber based paper materials was presented. In this paper, ZnO nanowires were grown on surface of para-aramid fiber(PPTA) by hydrothermal synthesis and were further functionalized with silane coupling agent KH550. Then, the PPTA@ZnO NWs-KH550 paper based composite was prepared by conventional papermaking process and thermal conductivity, insulation and mechanical properties of as-prepared composite were studied. Results showed that ZnO nanowires were successfully coated on the surface of PPTA. The thermal conductivity of PPTA@ZnO NWs paper based composite reached 0.455W/(m·K), increased by 115.64% compared with PPTA paper based composites. The dielectric strength of PPTA@ZnO NWs paper based composite mets the insulation requirements. After modified by silane coupling agent KH550, the thermal conductivity of PPTA@ZnO NWs-KH550 paper based composite was almost unchanged, the dielectric strength increased by 3.69% and the tensile strength increased by 58.75%, which indicated the composite exhibited excellent insulation and good mechanical properties. |
