摘　　要： 利用NaBH4作为还原剂,表没食子儿茶素没食子酸酯(EGCG)为稳定剂,还原RhCl3水溶液制备铑纳米颗粒,并用透射电镜(TEM)研究了铑纳米颗粒的形貌。通过静电纺丝技术制备了PEI/PVA纳米纤维,并用戊二醛作为交联剂使之交联以提高其耐水性。然后在交联过的PEI/PVA纤维膜上负载铑纳米颗粒;利用傅里叶红外光谱仪(FTIR)、扫描电子显微镜(SEM)对PEI/PVA以及Rh/PEI/PVA薄膜进行了表征。结果表明:利用静电纺丝技术和复合技术可以制备PEI/PVA超细纤维负载纳米铑的杂化材料。 This paper took NaBH4as the reducing agent and EGCG as the stabilizer to prepare rhodium nanoparticles by reduction of RhC13 water solution. Transmission electron microscope （TEM） was used to study the morphology of the as-prepared rhodium nanoparticles. PEI/PVA nanofiber was produced through electrospinning technology. Moreover, glutaraldehyde served as the cross-linking agent to improve the water resisting property. Rhodium nanoparticles were loaded on cross-linked PEI/PVA fiber membrane. Fourier transformation infrared spectra （FTIR） and Scanning electron microscopy （SEM） were used to characterize PEI/PVA and Rh/PEI/PVA film, The results indicated PEI/PVA superfine fibers loaded with nano-rhodium hybrid materials could be successfully prepared through electrospinning technique and composite technology.
