为拓宽纳米纤维网在医疗保健材料领域的应用，采用Ag/HBP分散液和聚丙烯腈（PAN）为原料，制备了一种新型的Ag/端氨基超支化聚合物HBP/聚丙烯腈（PAN）纳米纤维网，该纳米纤维网具有优良的抗菌性和过滤性。以HBP为还原剂和稳定剂，制备了Ag/HBP分散液，用Ag/HBP水溶液对静电纺丝PAN纤维进行改性，制备了Ag/HBP/PAN纤维。表征结果表明，制备的银纳米粒子呈球形，在HBP水溶液中分布较窄。用SEM和EDS对Ag/HBP/PAN复合材料进行了表征，结果表明，随着处理温度的升高，PAN复合材料表面银纳米粒子的含量增加。经HBP处理的PAN纤维对S. aureus和E.而Ag/HBP/PAN对S. aureus和E.由于HBP和Ag纳米颗粒中氨基的协同作用，对大肠杆菌的抑制率分别为99.9%和99.96%。Ag/HBP/PAN复合材料的微孔结构和高孔隙率使其对0.1 μm~0.7 μm颗粒的过滤效率高达99.9%，远高于普通口罩的过滤效率。
To widen the application of nanofibers web in the field of medical health materials, a new Ag/amino-terminated hyperbranched polymer HBP/polyacrylonitrile PAN nanofiber web with excellent antimicrobial activity and filtration property was produced with Ag/HBP dispersion solution and PAN nanofiber. Ag/HBP dispersion solution was prepared with HBP as reducer and stabilizer, and Ag/HBP/PAN nanofiber was prepared by modifying electrospun PAN nanofiber with Ag/HBP aqueous solution. The characterization results showed that spherical Ag nanoparticles were prepared and they had a narrow distribution in HBP aqueous solution. The results of Ag/HBP/PAN nanofiber characterized with SEM and EDS showed that the content of silver nanoparticles on the surface of PAN nanofiber was on the increase when the treating temperature rose. The bacterial reduction rates of HBP-treated PAN nanofiber against S. aureus and E. coli were about 89%, while those of the Ag/HBP/PAN nanofiber against S. aureus and E. coli were 99.9% and 99.96%, respectively, due to the cooperative effects from the amino groups in HBP and Ag nanoparticles. Moreover, the small pores and high porosity in Ag/HBP/PAN nanofiber web resulted in high filtration efficiency 99.9% for removing smaller particles 0.1 μm~0.7 μm, which was much higher than that of the gauze mask.
