本研究計畫是利用混掺方式精準調控團鏈共聚物微觀相分離及奈米微結構尺寸大小，建立此系統中物種間溶解度、組成體積分率，分子量大小與分子間作用力及微相分離結構與尺寸之關係。並進行各種與奈米微結構相關性質的測量與分析。再者，利用臨場(可控溫控濕)掠角式小角度X 光散射技術研究溶劑揮發及退火驅動力對混掺體薄膜微相分離奈米結構大範圍有序排向的影響。The research project will focus on precise control over phase behavior and nanostructure size in thin film and bulk using mixtures of diblock copolymers and homopolymers. First of all, fundamental relationships of species solubility, volume fraction, molecular weight and segment interaction with the size and the types of microdomains will be established based on structure characterizations by transmission/scanning electron microscopy (TEM/SEM), atomic force microscopy (AFM) and X-ray scattering/diffraction. Furthermore, the effects of solvent evaporation and annealing on the orientation of nanostructures in thin-film diblock copolymers/homopolymers mixtures are investigated by in-situ grazing incident X-ray scattering technology combined with environmental controls of temperature and humility.研究期間 : 9811 ~ 9910
