We studied the thermal insulation, antibacterial and mold properties of the nanofiber laminated wallpapers prepared by laminate-coating using electrospinning method. The thermal insulation capability of the nanofiber laminated wallpapers was evaluated by using a home-made insulated environmental chamber under different environmental conditions. It was found that the nanofiber laminated wallpapers exhibited better thermal insulation performance than the conventional silk wallpaper, which was commercialized silk wallpapers prepared by polyacrylic resin, suggesting that the laminate-coated nanofiber layer played an effective role in thermal insulation. Compared to the normal silk wallpaper, the nanofiber laminated wallpaper also exhibited good moisture vapor transmission rate (MVTR) due to excellent vapor permeability. In addition, TiO2-containing nanofiber laminated wallpapers exhibited good antibacterial activity against both E. Coli and P. Aeruginosa.
我们研究了采用静电纺丝法通过层压涂层制备的纳米纤维层压壁纸的保温、抗菌和防霉性能。在不同环境条件下，使用自制的隔热环境舱对纳米纤维层压壁纸的保温能力进行了评估。结果发现，纳米纤维层压壁纸表现出比传统丝绸壁纸更好的保温性能，传统丝绸壁纸是由聚丙烯酸树脂制备的商业化丝绸壁纸，这表明层压涂层的纳米纤维层在保温方面发挥了有效作用。与普通丝绸壁纸相比，纳米纤维层压壁纸由于具有优异的透气性能，还表现出良好的透湿率（MVTR）。此外，含TiO₂的纳米纤维层压壁纸对大肠杆菌和铜绿假单胞菌均表现出良好的抗菌活性。
