See full text

A polyimide and a method for manufacturing the polyimide are provided. The method for manufacturing the polyimide includes: mixing a diamine compound with a substance and an organic solvent, wherein the diamine compound includes an amide bond, and a molecular structure of the substance includes an ether dianhydride; and forming the polyimide by a cross-linking and curing process. A regular molecular chain arrangement, wherein the regular molecular chain arrangement has highly oriented in-plane crystallization and low free volume; a simple rigid planar structure; and intramolecular hydrogen bonds are introduced to prepare the polyimide that has high barrier performance, excellent heat resistance, and a low thermal expansion coefficient.
