CoMa: Utilizing water as a structural component in cellulose-based materials design

Updated: Sep 12, 2023

CoMa project is focusing on the fundamentals of water interactions in cellulosic substrates with the aim of utilising the information in functional materials, i.e., employing water as an asset rather than regarding it as a nuisance in cellulose-based materials. Top analytical tools will be exploited with the experimental constraints for the matrix set by computer simulations. Instead of focusing on just one parameter, we will explore the interconnections between water responsiveness, accessibility, geometrical constraints, and chemical composition. The knowledge will be utilised when controlling e.g. porosity/density balance of hydrogels, membranes and barriers in presence of water. CoMa follows the established scientific roadmap with the goal to open up new avenues to build materials that rely on high hygroscopicity of cellulose.
