題目:
Polymer Nanostructures Using Porous Templates
主講人:陳俊太 教授
現職:國立陽明交通大學 應用化學系 特聘教授
內容摘要:
Template wetting methods have been widely applied in the preparation of one-dimensional (1D) polymer nanomaterials. We study the fabrication and characterization of different polymer-related nanomaterials by wetting porous templates. We report novel smart nano membranes (SNM) that are made up of anodic aluminum oxide (AAO) templates grafted with spiropyran molecules. The ultraviolet and visible light responses of the SNM under acid vapors are investigated. Under UV irradiation, the ring-closed spiropyran on the AAO templates transform to ring-opened merocyanine, which contains phenolate oxygen and can be further protonated by acids. We also present a facile light-induced nanowetting (LIN) method to fabricate patterned nanoarrays. Photoresponsive azobenzene-containing polymers (azopolymers) that exhibit light-induced reversible solid-to-liquid transitions are used. Notably, using designed photomasks, the patterns of the nanoarrays can be ingeniously controlled with the characteristic of erasable and rewritable nanostructures. In addition, we demonstrate photoresponsive composite polymer electrolytes, consisting of gel polymer electrolyte (GPE) and spiropyran-immobilized nanoporous anodic aluminum oxide (SP-AAO) templates.
