Title:
SYSTEM AND METHOD FOR FORMING ACTIVATED CARBON AEROGELS AND PERFORMING 3D PRINTING
Document Type and Number:
WIPO Patent Application WO/2018/226576
Kind Code:
A3
Abstract:
Making a carbon aerogel involves 3-D printing an ink to make a printed part, removing the solvent from the printed part, and carbonizing the printed part (with the solvent removed) to make the aerogel. The ink is based on a solution of a resorcinol-formaldehyde resin (RF resin), water, and an organic thickener. Advantageously, the RF resin contains an acid catalyst, which tends to produce carbon aerogels with higher surface areas upon activation than those produced from methods involving an ink composition containing a base catalyzed resin.
