23 Jul Method for improving heat stability and mechanical property of polyvinyl alcohol nanofiber membrane
Abstract
The invention provides a method for improving the heat stability and mechanical property of a polyvinyl alcohol nanofiber membrane. The prepared polyvinyl alcohol nanofiber membrane has important application value in the fields of filtration, catalysis, fiber reinforcement, wound repair, tissue engineering, drug release and the like. The polyvinyl alcohol nanofiber membrane is prepared by mainly utilizing an electrostatic spinning technology and the polyvinyl alcohol nanofiber membrane with heat stability and mechanical property obviously improved is obtained by adding a few nontoxic and harmless third components with low cost and good water solubility to a polymer solution to directly carry out electrostatic spinning in the solution preparation process. The preparation method has the beneficial effects that the preparation method is simple to operate and has the advantages of low cost and obvious effect; the spinning process is stable; and the fibers have small diameters, are narrow in distribution and are light and pollution-free.
