The School of Materials Science and Engineering of Xiamen University recently broke through the key technology of continuous silicon carbide (SiC) free film with photoelectric characteristics, prepared a multi-component PCS precursor, and mastered the process of continuous SiC free film infusible crosslinking pretreatment and high temperature pyrolysis sintering. . At present, the technology has applied for 6 national invention patents, and has formed a small batch production capacity of continuous SiC free film materials. u003cbr /u003e
