项目摘要
The numerical experiments and computer simulations predicted the entropy driven assembly of the spheres segregated into the interstitial regions between the smectic layers formed by the rods in a rod-sphere mixture due to the depletion effect. In this study, the smectic liquid crystal supramolecular assembly of the mixtures of a sphere-like saturated branched alkane and rod-like polymers, poly[n-decyl-(S)-2-methylbutylsilane]s with narrow molecular weight distributions, were investigated by small-angle X-ray scattering (SAXS) measurements and atomic force microscopy (AFM) observations. It was revealed that the smectic layer spacings were proportionally increased with the amount of mixed alkane, which indisputably indicated that the additives were selectively inserted into the interstitial region of a pair of smectic layers of PDMS, and this trend was evident with the molecular weights of alkane at around 420. Making use of the aligned layer structure developed on the rubbed polyimide surface, the application for the wire grid polarizer has been studied, although successful procedurehas not been achieved at the moment.
