Problems solved by technology

Piezoelectric materials can be divided into inorganic piezoelectric materials and organic piezoelectric materials according to their composition. Among organic piezoelectric materials, poly(vinylidene cyanide / vinyl acetate) (P(VDCN / VAC)) is An organic piezoelectric material with high transparency, good flexibility and high thermal stability, but its bactericidal effect is not ideal after testing, so it is necessary to provide a P(VDCN / VAC) material with higher bactericidal performance

According to the nano piezoelectric fiber film material, a certain amount of two-dimensional nano piezoelectric material is introduced into P (VDCN / VAC), and the two-dimensional nano piezoelectric material and the P (VDCN / VAC) are matched with each other, so that the composite material has higher electroactive content while the flexibility and transparency of the P (VDCN / VAC) material are maintained, and the piezoelectric sterilization performance of the material is effectively improved.

Description

technical field [0001] The present application relates to the technical field of bactericidal piezoelectric materials, in particular to a nano piezoelectric fiber film material and its preparation method and application. Background technique [0002] At present, there are three main sterilization techniques commonly used, namely: the use of fungicides, heat treatment and radiation treatment. The sterilization time of fungicides is short, but they cannot be reused, and most of the fungicides are volatile and have certain damage to the human body and the environment, while heat treatment and radiation treatment are both harmful to the human body. Therefore, these methods are not suitable for the sterilization of mobile phone screens, elevator buttons, handrails and other areas in daily contact with the human body. Based on the above understanding, it is of great significance to adopt new sterilization technology in the above scenarios. [0003] In recent years, nano-piezoele...
