Photo‐Induced Depolymerisation: Recent Advances and Future Challenges

Abstract: Facing the growing environmental issues provoked by the use of nondegradable polymers in many fields (for example, packing, building, and clothing), tremendous efforts have been made to explore photodegradable materials to alleviate the increase in plastic pollution. Photodegradable materials would exploit significant advantages presented by the use of light, such as abundance, safety and the ability to easily tune intensity and wavelength. In particular, photo‐induced depolymerisation has received increasing … Show more

“…65 Photocatalysis has been explored as a means to enable plastics depolymerization using the energy from photons. 66 Photochemical reactions can allow for milder reaction conditions, and enable selective chemistries where reaction barriers would be too high using conventional techniques. Titania (TiO2) has been used in a variety of photocatalytic studies, owing to its ability to absorb UV light and generate highly reactive hydroxyl radicals.…”

“…A second major initiative to overcome the RLS trade-off was through the advancement of self-immolative polymers. These resists possess an alternative source of chemical amplification, and it was anticipated that the lack of acid diffusion would lead to simultaneous improvement of the RLS parameters. Examples include poly­(olefin sulfones), , poly­(esters), , and poly­(acetals). While many self-immolative resists are unable to achieve sensitivities comparable to typical CARs, a class of poly­(acetals), poly­(phthalaldehyde) (PPA), has proven to be one of the most promising due to its unprecedented rate of depolymerization in the solid phase.…”

“…Stimuli-degradable polymers (SDPs) have gained increasing attention due of their wide range of potential applications in various fields, including nano- and bio-technology as drug carriers and actuators, and in bio-patterning, etc [ 1 , 2 ]. Recently, SDPs have also attracted significant scientific and technological interest in the design of new recyclable and sustainable materials to eliminate the concerns of global environmental pollution from the non-degradable plastics [ 3 , 4 ].…”
