Problems solved by technology

PANI / ZnO is used as a functional composite membrane in the preparation of composite fabrics. There are no relevant reports. Whether the composite membrane can be successfully prepared needs to consider the following points: (1) Nano-ZnO is usually added to the fiber stock solution for melt spinning , can ensure good fastness, but cannot ensure that the ZnO particles embedded in the fiber are fully in contact with oxygen and moisture, so that the photocatalytic effect is weakened. At the same time, the prepared PANI / ZnO composite is directly added to the textile The problem of refractory and insoluble polyaniline will also be encountered in the silk liquid; (2) the post-finishing method using a dispersing finishing agent or a resin binder, although the method is simple, it is difficult to ensure the consistency of the nanocomposite particles in the finishing agent. Dispersion and uniformity, while finishing will reduce the physical properties of the fabric such as feel
