| Summary: | 博士 === 國立交通大學 === 應用化學系分子科學碩博士班 === 104 === To synthesize multi-functional materials, it is desired to develop simple methods to fabricate anisotropic particles. This dissertation mainly focus on developing novel methods, which are based on wetting and dewetting of polymers in the nanopores of anodic aluminum oxide (AAO) templates, to fabricate anisotropic polymer nanoparticles. This dissertation includes four parts. In the first part, we develop a simple approach to prepare curved polymer nanodiscs by thermal annealing induced wetting of polymer nanospheres in the AAO nanopores. In the second part, we develop a simple approach to prepare mushroom-shaped polymer nanoparticles by thermal annealing induced wetting of polymer nanospheres on the open end of AAO nanopores. In the third part, fluorescent polymer nanoparticles are prepared by different template methods to discuss the effect of morphology, chain arrangement and conformation on the photophysical properties. In the fourth part, we develop a simple approach to prepare porous polymer nanotubes by solvent annealing induced dewetting of polymer nanotubes in the AAO nanopores. The discussion of morphology control, wetting and dewetting behaviors, or applications of these four works are also included. This dissertation not only provide novel methods to fabricate anisotropic polymer nanoparticles, but also gives a better understanding of wetting and dewetting of polymers on curved substrates and under confined environments.
