Abstract

The invention provides an electrostatic spinning nanofiber membrane as well as a preparation method thereof. The electrostatic spinning nanofiber membrane provided by the invention comprises a fiber membrane obtained by electrostatically spinning a high-melting-point polymer and a fiber membrane obtained by electrostatically spinning a low-melting-point polymer, wherein the difference on the melting points of the high-melting-point polymer and the low-melting-point polymer is not less than 10 DEG C. The electrostatic spinning nanofiber membrane provided by the invention is multipurpose and can be applied to the fields such as biomedicines, energy and chemical industry, gas and liquid filtration, waterproofness and windproofness, windproofness and heat insulation, moisture permeability and ventilation, environmental management and semiconductor sensors. According to the electrostatic spinning nanofiber membrane provided by the invention, electrostatic spinning is respectively carried out on the high-melting-point polymer and the low-melting-point polymer, and the high-melting-point polymer fiber membrane and the low-melting-point polymer fiber membrane obtained are composited and hot-pressed to obtain the electrostatic spinning nanofiber membrane. The preparation method provided by the invention is high in production efficiency and low in energy consumption, and is suitable for industrial production.

Description

technical field

[0001] The invention relates to the technical field of electrospinning, in particular to a nanofiber film suitable for electrospinning and a preparation method thereof. Background technique

[0002] With the rapid development of industry, people have higher requirements for living environment and living comfort, while environmental pollution and energy reduction have become increasingly serious problems. At the same time, people's life and production have high requirements for air and liquid. . At present, existing technologies are accelerating research on environmental governance, new energy development, semiconductor industry and biomedicine.

[0003] In order to meet the above needs, for example: in terms of gas and liquid filtration, many polymer materials are used to make filter membrane materials, and many of them are commercialized such as polytetrafluoroethylene, polyphenylene sulfide, polyester fiber, and acetate fiber. However, the current product...
