A novel method to prepare a chitosan film using a newly developed apparatus in which the cast plate was loaded an electric charge was previously reported. In this study, the film prepared with or without the electric charge was characterized by X-ray diffractometry, differential scanning calorimetry (DSC), a microwave molecular orientation analyzer and an optical birefringence analyzer.X-Ray diffraction patterns indicated that the film prepared with an electric charge (VF) had higher crystallinity than the film prepared without an electric charge (NVF). These findings suggested that well-crystallized chitosan fibers were formed during the preparation of VF. Furthermore, chitosan fivers in VF had more preferred orientation.The DSC findings also indicated that the crystallinity of VF was higher than that of NVF. An electric charge during preparation of chitosan film might help making a particular fiber arrangement of chitosan macromolecules. The mechanical properties of VF and NVF reported previously were discussed from physicochemical characteristics of the films.
