Abstract
A nanofiber-containing membrane has a specific surface area of 0.1 to 1000 m2/g, porosity of 10 to 99.5% and a pore size of 0.01 to 10 μm. This provides a nanofiber-containing membrane having properties of high specific surface area, high porosity, nanoscale pore size, high pore uniformity and so on. A process for producing a nanofiber-containing membrane comprising producing a membrane from a polymer solution by electrospinning technology under optimal operation conditions.
