The invention relates to porous fiber comprising a polymeric material, said fiber having a diameter of 20 to 4000 nm and pores in the form of channels extending at least to the core of said fiber and/or through said fiber. n The process for producing the porous fiber comprises electrospinning a 5 to 20% by weight solution of at least one polymer in an organic solvent using an electric field above 10 5 V/m to obtain a fiber having a diameter of 20 to 4000 nm and pores in the form of channels extending at least to the core of said fiber and/or through said fiber. n The porous fiber may be used as a carrier for a catalyst, as an adsorbent or absorbent or as a biomaterial, may be chemically modified or functionalized or may be used as a template for producing highly porous solids. |
