本文报道了聚乙烯醇(PVA)/ baso4杂化纳米纤维的制备和表征。扫描电镜（SEM）分析表明，超声静电纺丝制备的PVA/ baso4杂化纳米纤维中baso4颗粒分散良好，无严重的团聚现象。x射线衍射（XRD）分析表明，静电纺丝过程中超声作用使PVA和baso4颗粒的典型晶峰明显降低。此外，baso4聚集体的大小变小。
We reported the preparation and characterization of the poly(vinyl alcohol) (PVA)/BaSO4hybrid nanofibers prepared by normal and ultrasonic electrospinning, respectively. Compared to normal electrospinning, BaSO4particles in the resultant PVA/BaSO4hybrid nanofibers prepared by ultrasonic electrospinning were well-dispersed without severe agglomerations, as confirmed by scanning electron microscopy (SEM) analysis. X-ray diffraction (XRD) analysis indicated that typical crystalline peaks of PVA and BaSO4particles were dramatically decreased by ultrasonication during electrospinning. Moreover, the size of BaSO4aggregates became smaller.
