抄録

Cellophane, which is a conventional cellulose film regenerated from viscose, has been used for a long time as a base for tapes and food packaging materials etc. This is because it has durability against many chemicals and has useful properties such as easy-cut and bacterial barrier properties. However, some drawback of moisture absorption and deformation remains. Thus, some improvements such as dimensional stabilities under high humidity are required. Cellophane has been manufactured from a solution of pulp dissolved as cellulose xanthate using harmful carbon disulfide. That is, much attention has been focused on ionic liquids (IL) as a novel solvent that can easily dissolve cellulose and is easier to be handled than carbon disulfide. Some papers reported that IL and IL/co-solvent systems can work as esterification media without any catalyst. In this study, we prepared cellulose/cellulose acetate films by coagulation method of blended ionic liquid solution to impart hydrophobicity to the regenerated cellulose film. The films were characterized by Fourier transform infrared spectroscopy (FT-IR), wide angle X-ray diffraction (WAXD), small angle X-ray scattering (SAXS), viscoelastic measurements, visible light spectroscopy, and contact angle measurements. In conclusion cellulose and cellulose acetate can be blended without phase separation to inhibit crystallization of each other. The third component, glycerol, also has a function of inhibiting crystallization of cellulose and cellulose acetate. It improves the film transparency and the molecular mobility of the celluloses.
