采用静电纺丝技术制备了PVP/[Sr(NO3)2+Mg(NO3)2+TEOS+Eu(NO3)2+Dy(NO3)2]复合纳米纤维,研究了不同静电纺丝工艺参数对其成纤性状的影响。结果表明:纤维的直径均随着电压、无机盐和PVP含量的增加呈现先减小后增大的趋势;随着纺丝液中无机盐含量的增加,纺丝液的黏度、表面张力和电导率均逐渐增大;随着PVP含量的增加,纺丝液的黏度、表面张力逐渐增大、电导率先减小后增大。SEM分析表明,当纺丝电压在13~15kV,纺丝液中无机盐含量为5%~6%,PVP含量为15%时,易获得形貌较好的复合纳米纤维。
The PVP / [Sr (NO3) 2 + Mg (NO3) 2 + TEOS + Eu (NO3) 2 + Dy (NO3) 2] composite nanofibers were prepared by electrospinning technique. The effects of different electrospinning parameters Effect of fiber formation. The results showed that the diameter of the fibers decreased firstly and then increased with the increase of voltage, inorganic salts and PVP content. With the increase of inorganic salt content in the spinning solution, the viscosity, surface tension and conductivity With the increase of PVP content, the viscosity and surface tension of the spinning solution gradually increased, the conductivity decreased first and then increased. SEM analysis showed that the composite nanofibers with better morphology were easily obtained when the spinning voltage was 13-15 kV, the inorganic salt content in the spinning solution was 5-6% and the PVP content was 15%.
