Polyvinylpyrrolidone Composite Nanofibers

Electrospinning technique has been proved to be a versatile and effective methodfor manufacturing one-dimensional nanomaterials. At the beginning of this century,scientists began to prepare various inorganic, organic, inorganic/organic compositenanofibers by electrospinning method. Inorganic/organic composite nanofibers havebeen applied widely in fields as diverse as optoelectronics, biological medicine,catalysis, efficient filtration, and sensor technology.In this thesis, we screened out poly (vinyl pyrrolidone)(PVP) with excellentbiocompatibility, poly (phenylene vinylene)(PPV) with excellent photoluminescence,electroluminescence properties as polymer matrix, ZnO nanoparticles with fluorescencecharacter were synthesized by hydration of alkoxide method, Au nanoparticles withelectricity character were synthesized by citric acid salt reduction method. We preparedPVP/ZnO, PPV/PVP/Au composite nanofibers successfully by combining wet-mixingwith electrospinning technology.The samples’ surface morphology and interal structure were characterized byscanning electron microscope (SEM), transmission electron microscope (TEM). Theperformance of PVP composite nanofibers were characterized by fourier transforminfrared spectrometer (FT-IR), X-ray diffraction (XRD), phosphorescence spectrum(PL), thermal analysis (TGA) and electrochemical instrument.
