MEH-PPV:PVP composite microstructures by an electrospinning technique: Structural and optical properties

In this paper, the formation of poly(2-methoxy-5-(2-ethylhexyl-oxy)-p-phenylenevinylene) (MEH-PPV) and polyvinylpyrrolidone (PVP) composite microstructures by an electrospinning technique has been reported. MEH-PPV:PVP composites have been prepared by using chloroform as solvent. Novel microstructures have been successfully formed at the varying concentrations of PVP at 1 wt%, 3 wt%, and 5 wt%. The morphological study of these structures has been characterized by Field Emission Scanning Electron Microscopy (FESEM), while their optical properties have been investigated by UV-vis, XRD, and photoluminescence (PL) microscopies. Enhancement in optical properties for the novel microstructures has been observed. The microstructures obtained from this study seem very promising for the applications in optoelectronic devices.
