Characterization of molecular processes during the development of adhesive contacts between cellulose surfaces using high resolution scattering techniques

Project description

In recent years, a large part of the public debate has focused on sustainability and renewable materials. And general interest in cellulose-based materials has increased significantly, and today an intense work is being done to use cellulose in different types of high-value products. Common to basically all of these applications is that cellulose surfaces are interacting with each other and other materials to create strong, lightweight and 3D-formable materials. Despite long-term research in the field, our knowledge of the molecular processes controlling these interactions is very limited. This is due, in part, to the lack of well-characterized cellulose model surfaces and due to the lack of high resolution measurement techniques to characterize the structure of the interfaces during the joining process and structure of the final mixing phase between the interacting materials. Now we have access to make well-defined model surfaces of cellulose, lignin and hemicellulose, and there are huge possibilities for determining these fundamental processes with different types of high energy scattering techniques, like SAXS/WAXS, GISAXS/ GIWAXS, and so on.
