Antibacterial activity and fire retardation are equally desired for protective clothing. For achieving this, AgNP and MgO are independently researched as nanofillers in Polyurethane based electrospun nanofibers and their synergistic effect is scarcely addressed. This article reports synthesis and characterization of MgO of 70.01 nm and AgNP of 51 to 76 nm by solution combustion and hydrothermal routes respectively and their incorporation in electrospinning of Polyurethane. Flow rate 1 ml/hr, applied voltage 13 kV, tip to collector distance 15 cm were adopted for the electrospinning. Nanofibers of 65 nm were obtained for PU/MgO (3 wt. %) and 106 nm for PU/MgO (3 wt. %)/Ag (1 wt. %). Addition of MgO increased the melting point, after flame time and afterglow time. Incorporation of AgNP improved antibacterial activity. PU/MgO/Ag (2 wt. %) exhibited zone of inhibition of 2.1 cm and 3 cm against E. Coli and S. Aureus, respectively.

防护服同样需要抗菌活性和阻燃性。为了实现这一点，AgNP和MgO作为基于聚氨酯的静电纺丝纳米纤维中的纳米填料被独立研究，几乎没有解决它们的协同作用。本文报道了分别通过溶液燃烧和水热法合成和表征70.01 nm的MgO和51至76 nm的AgNP的方法，以及它们在聚氨酯电纺丝中的掺入。静电纺丝采用的流速为1 ml / hr，施加电压为13 kV，针尖至集电极的距离为15 cm。对于PU / MgO（3重量％）获得65nm的纳米纤维，对于PU / MgO（3重量％）/ Ag（1重量％）获得106nm的纳米纤维。在火焰时间和余辉时间之后，MgO的添加增加了熔点。AgNP的掺入改善了抗菌活性。PU / MgO / Ag（2 wt。大肠杆菌和金黄色葡萄球菌，分别。
