摘要

利用分子间氢键和电荷相互作用力

通过层层喷涂组装技术

将带负电的氧化石墨烯(GO)与带正电的支化聚乙烯亚胺(bPEI)交替沉积到羊毛织物表面

制备(GO/bPEI)

涂层

再喷涂上一层聚磷酸铵(APP)

获得(GO/bPEI)

-APP修饰的阻燃抗菌羊毛织物。通过阻燃性能测试、热失重分析、导热性能测试和抗菌性能分析证明:相比于纯羊毛织物

通过层层喷涂组装技术获得的(GO/bPEI)

-APP修饰的羊毛织物的阻燃和抗菌性能显著提高。(GO/bPEI)

-APP修饰的羊毛织物的极限氧指数为30%

对金黄色葡萄糖球菌的抗菌率47%。实验进一步证实

将氧化石墨烯还原成还原氧化石墨烯(rGO)后

(rGO/bPEI)

-APP修饰的羊毛织物由于表面吸附更多的APP

所以其极限氧指数高达35%

对金黄色葡萄糖球菌的抗菌率也得到提升(64%)。

Abstract

In the present work

flame-retardant and antibacterial(GO/bPEI)

-APP wool fabric are fabricated by depositing alternately negatively charged GO and positively charged branched polyethylenimine (bPEI) and spraying a layer of ammonium polyphosphate (APP) on the wool surface. The results of flame retardant property analysis

thermogravimetric analysis

thermal conductivity test and antibacterial property analysis show that the flame retardant and antibacterial properties of the wool fabric modified by (GO/bPEI)

-APP were significantly improved. The limit oxygen index of (GO/bPEI)

-APP modified wool fabric was 30%

and the antibacterial rate against S. aureus was 47%. After reducing GO to rGO

the amount of APP adsorbed on the surface increased. The limit oxygen index of (rGO/bPEI)

-APP modified wool fabric reached 35%

and the antibacterial rate against S. aureus was up to 64%.
