    摘要:

    在溶液內(nèi)，利用聚丙烯酰胺為還原劑制備出了聚丙烯酰胺保護(hù)下的Au納米粒子。聚丙烯酰胺起到雙重作用，它是制備金納米粒子的還原劑；另外，它也是一種很好的金納米粒子的穩(wěn)定劑。紫外-可見光譜測試證實(shí)了溶液內(nèi)金納米粒子的存在，透射電鏡觀察到制得的納米纖維內(nèi)含有金納米粒子。這種新的路線對(duì)于制備其他功能性復(fù)合纖維有很好的借鑒作用

    Abstract:

    Gold nanoparticles were prepared in an aqueous solution with polyacrylamide to reduce HAuCl4. The polyacrylamide played double roles in the preparation of Au nanoparticles. Firstly, it acted as reducing reagent; in addition, it also stabilized the Au nanoparticles to prevent agglomeration and provided environment for forming nanostructure around Au nanoparticles. UV-vis spectra of the Au nanocrystals colloids reveal the plasmon resonance peak position. TEM confirms the presence of gold nanoparticles in the fibers. This is a versatile and applicable approach to prepare many other combinations of functional fibers electrospun
