Abstract: The present disclosure is directed to methods of forming polyimide gels. The methods generally include forming a polyamic acid and dehydrating the polyamic acid with a dehydrating agent in the presence of water. The resulting polyimide gels may be converted to polyimide or carbon xerogels or aerogels. The methods are advantageous in providing rapid or even instantaneous gelation, which may be particularly useful in formation of beads comprising the polyimide gels. Polyimide or carbon gel materials prepared according to the disclosed method are suitable for use in environments containing electrochemical reactions, for example as an electrode material within a lithium-ion battery.

Abstract: The present invention describes various methods for manufacturing gel composite sheets using segmented fiber or foam reinforcements and gel precursors. Additionally, rigid panels manufactured from the resulting gel composites are also described. The gel composites are relatively flexible enough to be wound and when unwound, can be stretched flat and made into rigid panels using adhesives.
