Partially deuterated cellulose derivatives for neutron contrast matching experiments
Cellulose derivatives are an important class of biopolymers, with an estimated production in excess of 10^6 ton/year. While neutron scattering techniques (e.g. SANS or spin echo) are a great tool to understand polymer conformation and dynamics, their application to cellulose polymers remains limited due to the lack of availability of deuterated cellulose. In this proposal, we outline a method to obtain partially deuterated cellulose derivatives. Our approach does not require the deuteration of the cellulose backbone, which is a costly and difficult step and instead relies on introducing HD contrast via acetylation with acetic anhydride. The purpose of the proposal is to demonstrate the feasibility of the proposed method. If successful, this would open up the use of neutron contrast matching techniques to cellulose derivatives and other polysaccharides.
