“…[8][9][10] Compared with the case of polyimide, the free radical population of a SiO 2 /PI composite was much higher and increased faster with the irradiation uence and the nano-SiO 2 lm thickness. 11 However for the polyimide ber, there were signicant differences in the performance due to the high degree of crystallization or orientation. [12][13][14] Wu Dezhen conducted a detailed study on the performance changes of high-strength and highmodulus polyimide bers in high temperature, strong acid, strong alkali, and ultraviolet irradiation environments, and compared them with P84.…”
Compared with the single irradiated sample, the tensile strength and elongation at break after the combination of proton irradiation and strain increased, indicating that introducing strain during irradiation will weaken the damage of irradiation.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
