静电纺丝技术制备聚乙烯吡咯烷酮—碘复合纳米纤维与表征

Preparation and Characterization of PVP-I Nanofibers by Electrospinning Technique

采用静电纺丝技术,以聚乙烯吡咯烷酮(PVP)、无水乙醇和碘为原料,成功地制备出聚乙烯吡咯烷酮—碘复合纳米纤维,并利用红外光谱仪、拉曼光谱仪、X射线衍射仪对产物进行了表征.结果表明,所得产物为聚乙烯吡咯烷酮—碘复合纳米纤维.

PVP-I nanofibres have been successfully prepared by electrospinning technique by using polyvinyl pyrrolidone,iodine and absolute ethanol as starting materials.The products were characterized by infrared spectra,raman spectra and X-ray diffraction.In the composite nanofibers,chemical bonding existed between polyvinyl pyrrolidone and iodine to form PVP-I complex.
