Summary: | Novel three-dimensional renewable phytic acid (AP) aerogel electronics were synthesized through in-site polymerization and oriented lyophilization method. Three stages of the aerogels were apparently observed via SEM and TEM tests: the honeycomb structure consituted the first stage; the network with micropores formed the second stage; the third stage was composed of nanopores structure inside the micropores. When the molar ratio of aniline and phytic acid reached certain degree, the AP aerogel will emerge high pore volume and excellent specific capacitance. What’s more, the mechanical properties of AP aerogel were about 5 times (9 times for electrical properties) higher in vertical direction than those in horizontal direction. To sum up, the three-dimensional AP aerogel owned great mechanical and electrical properties in specific direction, at the same time, it exhibited outstanding specific capacitance (448 F.g-1).
