靜電紡絲法製備二氧化鈦之奈米纖維表徵及形態

Abstract

中文摘要 以聚乙烯吡咯烷酮(Polyvinyl pyrrolidone; PVP)作為靜電紡絲之基材，與溶膠凝膠法所製備出的二氧化鈦微球均勻混合，並透過靜電紡絲法(electrospinning; ESP)製備出線徑均一的奈米級纖維，藉由改變工作距離、施加電壓、收集器轉速及溶液濃度等各項製成參數，以探討這些參數對PVP紡絲纖維形貌與結構之影響，並使用材料分析儀器如掃描式電子顯微鏡(SEM)、傅立葉轉換紅外光譜儀(FTIR) 和X光繞射儀(XRD)進行樣品顯微結構分析。

Abstract Polyvinylpyrrolidone (Polyvinylpyrrolidone; PVP) is used as the substrate for electrospinning, and it is evenly mixed with the titanium dioxide microspheres prepared by the sol-gel method, and the wire diameter is prepared by electrospinning (electrospinning; ESP) Uniform nano-grade fiber, by changing the working distance, applied voltage, collected voltage, collector conversion and solution concentration and other conversion parameters, and according to these parameters on the PVP spinning fiber morphology and structure, and use material analysis equipment Such as scanning electron microscope (SEM), Fourier transform infrared spectrometer (FTIR) and X-ray diffractometer (XRD) to analyze the microstructure of the sample.
