Photo-switched biodegradable plastic that suppresses biodegradation under light irradiation via a g-C3N4 photocatalyst
and polycaprolactone demonstrated distinct photo-switching functionality: complete suppression of biodegradation under light irradiation, contrasted with normal degradation kinetics in dark conditions when exposed to marine bacteria (Alcanivorax xenomutans). This approach provides a viable strategy for materials that require stability during application while ensuring biodegradability in light-limited marine disposal environments.
