摘要
Aramid paper based on poly (p-phenylene terephthamide) (PPTA) is a typically excellent insulation material, but the common preparation is complex and tedious. In this work, using the PPTA based aramid nanofibers (ANFs) synthesized by the bottom-up polymerization induced self-assembly process, insulation paper was fabricated through the vacuum assisted filtration without any high pressure or high temperature treatment. Importantly, the ANF paper exhibits improved electrical insulation, desired mechanical strength and good thermal stability, which is attributed to the tightly weaved architecture formed by the nanofibers.
