Degradation of polyimide films modified by carbon nanotubes under electron beam irradiation and tensile stress

In order to meet the needs of spacecraft for high-performance materials, polyimide (PI)/carbon nanotubes (CNTs) composite films were prepared and their performance changes under the coupling effect of electron beam irradiation/tensile stress were studied. The results showed that the PI/CNTs composite films had excellent mechanical properties and radiation resistance, and can be used as a promising candidate material for space applications.
