Cellulose is a natural organic polysaccharide that makes up most of a plant’s cell walls, which is composed of β linked d-glucose units in a linear chain. For this particular study, ionic liquids (ILs) will be used to functionalize the backbone of cellulose, since native cellulose is not a conductive material. Upon functionalization, the morphology and chemical properties were modified to control the ionic conductivity. Not only can these new materials be used as an electrolyte membrane, but also as filtration membranes to remove carbon dioxide and as bionics in the medical field. In order to observe the different morphological changes, as well as the thermal and conductivity properties of the new synthesized cellulose-based poly ionic liquids, several different characterization techniques will be performed. These tests include Fourier transform infrared spectroscopy (FTIR), thermal gravimetric analysis (TGA), differential scanning calorimetry (DSC), nuclear magnetic resonance (NMR), X-ray scattering, and ionic conductivity.
