Nanocellulose is of increasing interest for a range of applications relevant to the field of material science due to its excellent mechanical properties and tunable surface chemistry. Chemical modification is typically employed to tune physical and chemical features of nanocellulose through the various chemical reactions such as amidation, esterification, and silyation. When prepared films by using modified nanocellulose, this chemistry may change packing density as well as thermodynamic void (i.e., free volume), which provides a significant effect on the gas transport properties. To relate physicochemical features with gas transport properties, we here study the gas permeation of nanocellulose membranes, which are physicochemically modified by using various type of chemical modifiers with different chain length. Furthermore, we employed dialysis membrane to exactly controlled backbone structures. More detail will be presented in this poster. |
