Abstract

Monodispersed polyacrylonitrile (PAN) microspheres shape have been successfully synthesized by dispersion polymerization in the presence of polyvinylpyrolidone (PVP) as stabilizer. Transmission Electron Microscopy (TEM) and Particle Size and Distribution Analyzer were used to characterize the morphology and dispersibility of PAN microspheres, respectively. Fourier Transform Infrared (FTIR) and Nuclear Magnetic Resonance (NMR) were applied to characterize the structure of PAN. Finally, the crystallinity of PAN microspheres was investigated by X-ray Diffraction (XRD). The results show that PAN microspheres have a regular sphere shape and narrow dispersity with a monodispersity index of 1.17. The crystallization of PAN and the existence of PVP layer affect the morphology of PAN microspheres. The effects of various polymerization factors on the particle size distribution of PAN microspheres have also been studied. © 2012 Wiley Periodicals, Inc. J Appl Polym Sci, 2012
