    摘要： A method of forming a polymeric material includes forming a solution including at least two solvents and at least two diamines. The at least two diamines include oxydianiline (ODA) in an amount of about 50% to about 90% based on the total moles of the at least two diamines and include m-phenylenediamine (MPD) in an amount of about 10% to about 50% based on the total moles of the at least two diamines. The at least two solvents include a high polarity solvent in an amount of about 40% to about 90% based on the total weight of the at least two solvents and include a low polarity solvent in an amount of about 10% to about 60% based on the total weight of the at least two solvents. The method further includes adding pyromellitic dianhydride (PMDA) to the solution in a ratio of about 0.9 to about 1.05 based on the total moles of the at least two diamines to form a polyamic acid solution. In addition, the method includes imidizing the polyamic acid solution to form a polyimide material.
