博士 === 國立交通大學 === 應用化學系碩博士班 === 107 === When polymers are introduced into nanoporous templates, polymer nanomaterials can be obtained. Their structures at different scales, from chain alignments and phase-separated morphologies on a single nanostructure to the overall replicated nanostructure arrays, can be affected and controlled by the porous templates, polymers, infiltration approaches, and other parameters applied. In this thesis, we discuss the morphology control of polymers confined in cylindrical nanopores and the characterization of replicated polymer nanostructure arrays. For the morphology control of polymers, microphase-separated morphologies of block copolymers confined in cylindrical nanopores are mainly studied. By imposing several parameters, such as annealing solvents (Chapter 3) and homopolymer additives (Chapter 4), various morphologies of block copolymer nanostructures can be obtained. We then characterize the effects of these parameters on the morphologies of block copolymer nanostructures. In Chapter 5, morphologies of amphiphilic block copolymer micelles confined in cylindrical nanopores are controlled by the annealing solvents and the hybridization with inorganic percursors. For the characterization of nanostructure arrays (Chapter 6), ionic diodes with interfacial interdigitated nanostructures are prepared by sequentially polymerizing and crosslinking ionic liquid monomers in AAO nanopores. By increasing the interfacial areas of ionic diodes using the template method, the “ionic double layer” capacitance is subsequently increased, which is further demonstrated as a device for mechanical energy harvesting. To sum up, this thesis provides a deeper understanding to the morphology control of polymers on a single nanostructure (microphase-separated morphologies of block copolymers) and characterizations of replicated nanostructure arrays (ionic diodes with interfacial interdigitated nanostructures).
