We developed a method for fabrication of copper nanoparticles inside cotton fibers. Copper nanoparticles can be fabricated mainly in the central part of the fiber by absorbing a raw material solution and by applying microwave heating in a state where the raw material solution is pressed with immiscible liquids. Surface SEM images and cross-sectional EDS mapping for the fabricated fibers clarified that copper nanoparticles fabricated on the cotton surface were suppressed considerably more by the hydrophobic raw material solution than by the hydrophilic raw material solution. These cotton fibers containing copper nanoparticles were found to have antiviral properties against the influenza A virus.
我们开发了一种在棉纤维内部制造铜纳米颗粒的方法。通过吸收原料溶液并在原料溶液被不混溶液体挤压的状态下施加微波加热，铜纳米颗粒主要可以在纤维的中心部分制造出来。对制造的纤维进行的表面扫描电子显微镜图像和横截面能谱映射表明，疏水性原料溶液比亲水性原料溶液更能显著抑制在棉花表面制造的铜纳米颗粒。发现这些含有铜纳米颗粒的棉纤维对甲型流感病毒具有抗病毒特性。
