Researchers at Flinders University have utilized ultraviolet (UV) light to synthesize sustainable and recyclable sulfur-rich polymers. This advancement, published in the Journal of the American Chemical Society, enhances the adaptability and affordability of these materials for high-value applications, including lithium-sulfur battery components and antimicrobial agents.

The team, in collaboration with the University of Tasmania and Deakin University, demonstrated that shining UV light on monomer building blocks effectively connects them, while pulsed LED light further improves the polymers' green credentials. The method allows for recycling using UV light or heating above 150°C, enabling the reuse of monomer building blocks. This synthesis approach offers mild and sustainable conditions for producing high molecular weight sulfur polymers, expanding their potential applications.
