Cyclic stability and self-recovery behavior of UVC ML elastomer. a ML emission spectra and b ML intensity evolution of the SBO:Pr/PDMS elastomer film over 10,000 continuous stretching cycles (frequency: 5 HZ; strain: 40%). c Corresponding UVC ML images of the film recorded throughout the 10,000 stretching cycles. d ML emission spectra and e ML intensity recovery of the elastomer film after being naturally placed at room temperature for varying durations from 1 s to 24 h following 10,000 continuous stretching. f ML emission spectra over five consecutive cycles following 12 h of natural recovery. g ML repeatability performance under various time intervals between mechanical stimuli. h ML emission spectra and i corresponding intensity evolution of the elastomer film subjected to 2000 continuous rubbing cycles (frequency: 5 HZ; applied force: 5 N)
