DESIGNER MOLECULES FOR ONE-STEP MODIFICATION OF CELLULOSE IN AQUEOUS AND ORGANIC SOLVENTS HOW DOES IT WORK? Designer synthetic molecules target cellulose hydroxyl groups producing functional cellulose ether derivatives WHAT PROBLEM DOES IT SOLVE? 1 wt % CNC • Relative chemical inertness of cellulose • Non-dispersion of cellulose in organic solvents • Incompatibility of cellulose with polymer matrices 1 wt % CNC WHO COULD BENEFIT? WHAT PRODUCTS COULD IT MAKE? WHY IS IT NOVEL? • Robust and versatile technology • Various chemical functionalities introduced in one-step • Works at room temperature in aqueous and organic solvents • Our chemistry is cost effective, can be implemented on a large scale and applied to a wide range of products • Functionality can be transferred irrespective of the scale – from microcrystalline cellulose fibres to nanocrystals Reaction time • Reinforced nanocomposite materials for tissue engineering, containers for packaging and building applications • Fabrication of paper based diagnostics lab on a chip device • Moisture repellent textile/paper, paper additives and dyes • Biodegradable conductive thin films for nanoelectronics • Stimuli responsive films for drug delivery Ayodele Fatona, Michael A.
