The physical behaviors of polymers under nanoscopic confinement have been of scientific interest during the past few decades. Investigation of polymer crystallization behaviors within one-dimensional nanostructures is an important area due to the potential applications of nanostrutured crystalline polymers such as nanoelectronic devices, sensors, and photovoltaic cells as well as fundamental scientific interests. In this work, we examine the crystalline structures, melting and crystallization behaviors of monodisperse poly(ethylene oxide) confined to nanocylinders using XRD and calorimetric measurements. The crystal orientation, melting and crystallization behaviors of PEO under the imposed confinement were noticeably different from those of the bulk state and cylinder-forming PS/PEO diblock copolymers. |
