Christian-Doppler-Laboratory "Advanced Cellulose Chemistry and Analytics"
Abstract
Cellulose is the most abundant natural and renewable polymer. Another superlative is its importance as natural product, both with regard to its economic value and to the breadth of its applications. It is the basis of whole industrial branches, such as the paper industry and major parts of the textile industry. With the increasing focus on natural resources and sustainability issues, also cellulose has been undergoing a surge of interest both from the academic viewpoint and the industrial perspective. In addition to the classical cellulose chemistry which is mainly connected with large-scale pulping, bleaching and paper-making / fiber-making techniques, current cellulose research is directed towards an “advanced understanding and advanced applications of this most important bioresource” (Panel of the 2nd International Cellulose Conference, 2007). This includes the following “hot” scientific topics, on which will be focused within the framework of the new CD-laboratory for Advanced Cellulose Chemistry and Analytics: • Molecular-level characterization of celluloses beyond the classical sum parameters. • Advanced understanding of cellulose swelling and dissolution on a molecular basis. • Highly functionalized cellulosic products taking advantage of the intrinsic properties of the polymer in combination with modern modifying reagents. • Advanced understanding of cellulose degradation and aging as the basis to extend lifecycles and maintain the value of historic cellulosic products and cultural heritage. The work is conducted in four modules, each one being assigned to one of the four industrial partners: • Module 1: “Non-conventional celluloses from renewable resources: structure and processability” • Module 2: “Novel sizing agents based on renewable resources and their binding mode to cellulose” • Module 3: “Mass deacidification and damage control of valuable historic paper objects” • Module 4: “Intelligent cellulosic tissue modified with advanced slow- release reagents” • Modul 5; "Products and follow-up chemistry of (hemi)cellulose degradation”
