Scientists make sustainable polymer from sugars in wood

Scientists from Bath's Centre for Sustainable and Circular Technologies have made a sustainable polymer using the second most abundant sugar in nature, xylose. Last updated on Monday 11 January 2021 - Not only does the new nature-inspired material reduce reliance on crude oil products, but its properties can also be easily controlled to make the material flexible or crystalline. The researchers, from the University's Centre for Sustainable and Circular Technologies , report the polymer, from the polyether family, has a variety of applications, including as a building block for polyurethane, used in mattresses and shoe soles; as a bio-derived alternative to polyethylene glycol, a chemical widely used in bio-medicine; or to polyethylene oxide, sometimes used as electrolyte in batteries. The team says additional functionality could be added to this versatile polymer by binding other chemical groups such as fluorescent probes or dyes to the sugar molecule, for biological or chemical sensing applications. The team can easily produce hundreds of grams of the material and anticipate that production would be rapidly scalable. Dr Antoine Buchard, Royal Society University Research Fellow and Reader at the Centre for Sustainable and Circular Technologies, led the study. He said: "We're very excited that we've been able to produce this sustainable material from a plentiful natural resource - wood.
