YAG/Al2O3/ZrO2 composite fibers of core-shell structure prepared by electrospinning

Abstract

ABSTRACT As the performance of each component is complementary, the performance of alumina-basedAs the performance of each component is complementary, the performance of alumina-basedcomposite fiber is much better than single-component fiber. However, it is difficult to preparecomposite fiber is much better than single-component fiber. However, it is difficult to prepareAs the performance of each component is complementary, the performance of alumina-basedAs the performance of each component is complementary, the performance of alumina-basedcomposite fiber is much better than single-component fiber. However, it is difficult to preparecomposite fiber is much better than single-component fiber. However, it is difficult to prepare. In this paper, YAG/Al2O3/ZrO2 composite fibers were successfully prepared by electrospinning method. The effects of spinning process parameters on structure and the morphology of composite fibers were studied, such as applied voltage, tip-collector distance, polymer concentration, etc. The result showed the YAG/Al2O3/ZrO2 composite fibers with a smooth surface and an average diameter of 250 nm were obtained when the polymer concentration was applied voltage was 25 kV, the tip-collector distance was 16 cm, calcination and the temperature was 1300°C. It was also found YAG/Al2O3/ZrO2 composite fibers were single crystal with core-shell structure and then the formation mechanism of fiber was studied.
