    摘要： Disclosed is a method of forming a polyimide coating in a pattern on a surface. A first solution is prepared of an organic solvent, and diamine and dianhydride monomers. The monomers are polymerized to form a polyamic acid that is soluble in the organic solvent. About 10 to about 95% of the amic acid groups in the polyamic acid are imidized, forming a partially imidized polyamic acid. A more concentrated solution of the partially imidized polyamic acid is prepared and about 0.1 to about 10 wt % of a thixotrope is mixed with the more concentrated solution to form a paste. A template is placed over the surface and the paste is forced through the template onto the surface. The solvent is evaporated and the partially imidized polyamic acid on the surface is fully imidized.
