在聚乙烯吡咯烷酮（PVP）乙醇溶液中，用柠檬酸三钠还原HAuCl 4制备了金纳米粒子，并通过静电纺丝将其分散到PVP纳米纤维中。采用紫外-可见光谱法对静电纺丝前后Au纳米粒子的光学性质进行了测试。用透射电子显微镜（TEM）观察了金纳米粒子在PVP纳米纤维中的形态和分布。研究了静电纺丝液中Au的添加量和PVP浓度对Au/PVP纳米纤维形态的影响。(c)2007 Wiley Periodicals，Inc.
Gold nanoparticles prepared by trisodium citrate reduction of HAuCl4 in poly(vinylpyrrolidone) (PVP) ethanol solution were dispersed into PVP nanofibers by electrospinning. The optical property of Au nanoparticles before and after electrospinning was measured by UV-Vis. The morphology and distribution of gold nanoparticles in PVP nanofibers were observed by transmission electron microscopy (TEM). The influence of the amount of Au added to and the concentration of PVP in electrospinning solution over the morphology of Au/PVP nanofibers were studied. (c) 2007 Wiley Periodicals, Inc.
