摘 要聚酰亚胺（PI）具备优异的力学、热稳定性能与加工性能，在空间太阳能电池柔性盖片领域应用前景广阔，但分子内及分子间的电荷转移络合物效应制约其光学透过率提升。本文采用化学亚胺法合成聚酰亚胺，结合电子束蒸镀技术、利用光学匹配减少界面反射，制备高透明聚酰亚胺复合薄膜。该薄膜分别经能量1 MeV、100 keV，注量6.7×10¹⁴ e·cm⁻²、2×10¹⁵ e·cm⁻²电子辐照后，光学、力学及热学性能未出现明显衰减，展现出优良耐辐照能力，可应用于空间太阳能电池柔性盖片。

Abstract Polyimide (PI) has excellent mechanical properties, thermal stability and processability, and has great application potential for flexible cover sheets of space solar cells. However, the charge transfer complex effect inside and between PI molecules limits the improvement of optical transmittance. In this work, polyimide was synthesized by chemical imidization method. High-transparency PI composite films were fabricated via electron beam evaporation technology by means of optical matching to reduce interfacial reflection. After electron irradiation with energy of 1 MeV and 100 keV as well as fluence of 6.7×10¹⁴ e·cm⁻² and 2×10¹⁵ e·cm⁻², the optical, mechanical and thermal properties of the composite films did not degrade obviously, showing outstanding radiation resistance. The films have good application prospects for flexible cover sheets of space solar cells.
