The present invention relates to a polyimide airgel using an SLA-3D printer and a method for manufacturing the same. In order to solve the problem that the conventional method for manufacturing polyimide airgel is not environmentally friendly, takes a considerable amount of time, and requires expensive equipment, , A polyimide airgel manufacturing method using a tertiary amine-based photocuring agent and a SLA-3D printer is provided. The manufacturing method according to the present invention is eco-friendly by using water as a solvent, and the tertiary amine-based photocuring agent forms a salt form, resulting in crosslinking between polyamic acid chains, so that when freeze-dried, it is porous and has a delicate shape using a 3D printer. It is possible to manufacture, and there is an advantage that the manufacturing time is shortened. |
