Multifunctional silk fabric with ultraviolet radiation protection and antibacterial activity was successfully fabricated by grafting graphene oxide (GO) nanosheet dispersion onto the surface of the fabric. The structure and morphology of the as-obtained modified silk fabrics were characterized by SEM, AFM, FTIR and Raman, and the results indicate that the synthetic GO nanosheet distribute uniformly onto the surface of the silk fabric, and there is one hydrogen bonding between silk fabric and GO. As expected, the ultraviolet protection factor (UPF) was applied to evaluate UV blocking and the silk fabrics modified with GO showed more than 54-fold increase with a UPF value of 232.69 than that of control silk (UPF rating at 4.28). Furthermore, GO treated silk fabric showed excellent antibacterial activity with the survival rates of E. coli and S. aureus of (14.2 ± 4.1) % and (4.8 ± 1.6)% respectively. Moreover, the GO treatment had little effect on the permeability of fabrics. The GO treated silk fabric is effective for cycling use. The functional silk fabrics can be applied to high-grade outdoor leisure fabrics.

通过将氧化石墨烯（GO）纳米片分散体接枝到织物表面上，成功制备了具有紫外线辐射防护和抗菌活性的多功能真丝织物。用SEM，AFM，FTIR和Raman表征了所得改性真丝织物的结构和形貌，结果表明合成的GO纳米片均匀地分布在真丝表面，真丝之间存在一个氢键面料和GO。如预期的那样，应用紫外线保护因子（UPF）评估紫外线的阻隔性，用GO改性的真丝织物的UPF值为232.69，比对照真丝（UPF值为4.28）提高了54倍以上。此外，GO处理的真丝织物具有优异的抗菌活性，并具有大肠杆菌和S的存活率。金黄色素分别为（14.2±4.1）％和（4.8±1.6）％。而且，GO处理对织物的渗透性影响很小。经过GO处理的真丝织物可有效循环使用。功能性真丝面料可应用于高档户外休闲面料。
