Abstract:
Novel types of layer-by-layer (LbL) assembly films were successfully fabricated onto a solid substrate through the inclusion complex formation between partially 2,3- O-methylated amyloses (MAs) and polytetrahydrofuran (PTHF). The formation of the LbL assembly films was confirmed by quartz crystal microbalance (QCM) analysis, atomic force microscopy (AFM) observation, and X-ray diffraction (XRD) measurement. The film formation was significantly affected by the methylation degree of amylose. When MAs with 8 and 20% methylation were used as hosts, the formation of LbL assembly films with PTHF was clearly observed. On the other hand, MAs with more than 33% methylation barely formed LbL assembly films with PTHF.
