"Synthetic carbohydrate polymers from xylose"
Abstract: The intensive use of polymers has brought challenges associated with their overwhelming reliance on fossil-fuel resources, limited end-of-life options and environmental persistence. We need to move away from our reliance on fossil-based polymers and towards a circular economy. Our vision of sustainable polymers involves creating materials derived from renewable feedstocks and with multiple closed-loop life cycles, such as mechanical and chemical recycling or biodegradation.
However, one major challenge is to obtain materials with adequate properties. Towards this goal, our team has been investigating the incorporation of monosaccharide units into synthetic polymer backbones. Our hypothesis is that because sugars are natural, abundant, non-toxic, biodegradable, biocompatible, and highly functionalisable, renewable materials with desirable attributes could be made. In particular, we have identified D-xylose as a promising precursor for the preparation of bio- derived and functionalised polymers, due to its abundance and low cost.
