Problems solved by technology

Although PTFE microporous membrane has excellent waterproof and moisture-permeable performance, it is expensive, monopolized by foreign technology, and equipment and raw materials are difficult to stabilize, resulting in unstable product quality. difficult, which limits its field of application
TPU hydrophilic film has high water pressure resistance due to its non-porous structure, but its moisture permeability is poor, and it is easy to get wet when it encounters water, which makes the human body feel uncomfortable, so it is limited to the low-end market

The average diameter of the fiber is 130 to 150 nm, the nanofiber waterproof and moisture permeable composite film is of a three-dimensional network structure, the hole diameter is small, a curved communication hole structure is formed, breathability is good, external severe weather infringement can beeffectively avoided, rain and snow penetration is prevented, sweat and moisture generated by movement of a human body can be discharged in time, so that the microenvironment of the human body is regulated and controlled, good comfort is provided for the human body, the protection function and the heat and moisture comfort of the garment fabric are unified, and the composite fabric is innovativelyapplied to the fields of medical treatment and public health, building outer walls, aerospace, aquatic product industry and the like.

Description

technical field [0001] The invention belongs to the field of electrospinning functional materials, and relates to a method for preparing materials applicable to the waterproof and moisture-permeable field, in particular to a waterproof and moisture-permeable composite fabric containing fluorinated graphene and a preparation method thereof. Background technique [0002] Waterproof and moisture-permeable clothing, because it can block the external bad weather and prevent rain and snow from penetrating, it can also timely discharge the sweat and moisture generated by the human body due to exercise, thereby regulating the microenvironment of the human body to provide good comfort for the human body. The protective function and heat and humidity comfort of clothing fabrics are unified, so they are vividly called "breathable fabrics", which has attracted extensive attention from industry and academia. Commonly used waterproof and moisture-permeable garments include high-density fa...
