Summarize

This paper develops an environmentally friendly, highly elastic nanofiber membrane, which achieves excellent waterproof and breathable properties through electrospinning technology combined with innovative material design. The research aims to abandon fluorine-containing chemicals and use green polyurethane-based materials to meet the needs of sustainable development. The obtained membrane exhibits high tensile strength and large elongation at break, as well as good hydrostatic pressure and water vapor transmission rate (WVT), and maintains stable performance after multiple washing and stretching. This research provides new environmentally friendly solutions for protective equipment, medical health and filter materials, with significant potential for industrial application.

Method

This paper discusses a method for preparing and optimizing the properties of an environmentally friendly, highly elastic nanofiber membrane. Through electrospinning technology, researchers used fluorine-free materials to develop a composite membrane with excellent mechanical properties, waterproofness, and breathability.

Research highlights

Environmentally friendly material selection:

The high-performance nanofiber membrane is prepared using fluorine-free materials, abandoning traditional fluorine-containing chemicals, which meets the environmental protection requirements of sustainable development. The polyurethane-based material used not only has excellent elasticity and mechanical properties, but also has strong durability and environmental friendliness.

Excellent performance:

High tensile strength and high elongation at break provide better stability and durability for flexible applications. The prepared membrane has good water vapor transmission rate (WVT) and hydrostatic pressure, ensuring the dual needs of protection and comfort. The membrane maintained good performance after repeated stretching and washing, showing excellent durability.

Potential application prospects:

The results of this research are applicable to personal protective equipment, the medical field, and high-performance filtration materials, providing new solutions and technical paths for related industries.
