제목 Crystalline Structures and Crystallization Behaviors of Polyethylene Confined to Nanocylinders
초록 The crystallization and melting behaviors of monodisperse linear polyethylene confined in cylindrical nanopores were investigated. The crystalline structures, melting, and crystallization behaviors of PE under the imposed cylindrical confinement were noticeably different from those of the bulk state. There is a drastic change in crystallization behavior, specifically nucleation, with a decrease in the pore diameter. Crystallization in relatively larger pores with the diameters occurs at lower temperatures within a very narrow range, whereas crystallization in smaller poresoccurs at a higher and broad range of temperatures. The melting temperature in the nanopores was substantially depressed.
