폴리벤즈옥사졸 전구체를 이용한 나노섬유의 제조 = Preparation of Nanofibers Using Precursor Polymers to Polybenzoxazoles

다국어 초록 (Multilingual Abstract)

Polyhydroxyamide, a precursor polymer to polybenzoxazole, was synthesized by low temperature polymerization of dihydroxybenzidine and isophthaloyl chloride. The polyhydroxyamide solution was electro spun under appropriate concentration, viscosity, electrical conductivity, voltage and tip collector distance. Electrospun polyhydroxyamide fibers were heated at the elevated temperature and converted to polybenzoxazole fibers. In this study we investigated the effects of the electrospinning factors, such as solution viscosity, concentration, and electrical conductivity on the fiber formation of polyhydroxyamide during electro spinning. The electrospun polyhydroxyamide nanofibers showed broader DSC endothermic peak as compared to film or powder samples, which was thought to be due to the large sur-face area of nanofiber web.
