Sustainable material design can alleviate the environmental burden related to material waste. Use of available and abundant resources, create materials that can be recycled, and final degradability in nature is central to achieve this. The overarching aim of the proposal is to holistically design new materials from cellulose fibers by; developing new sustainable modification strategies, evaluate material property space, recycling and degradation characteristics combined with a theoretical predictive models. This will enable design of materials with predicted properties and tailored degradation profiles. C ombining recent advances in ring-opening reactions with state-ofthe- art knowledge in solvation or partial solvation of cellulose fibers will enable the creation of both thermoplastic polymers and thermoplastic fibers. Degradation profile is tightly connected to the structure of the modification and its ability to hydrolyze, but also to the ability for water to penetrate through the material. To get molecular understanding on the degradation pathway, both degradation behavior and theoretical models on hydration will be applied. This project provides a conceptual starting point on how we can make the next generation of plastic from the forest designed for the future. These polymeric materials have the potential to rival traditional petroleum based polymers in terms of properties, while at the same time being renewable, sustainable and degradable.
