Abstract

The present invention relates to a method for manufacturing a fibrous structure comprising: Forming a fibrous pre-structure from fibers and a material including self-assembled nano-domains, and treating the material including self-assembled nano-domains in such a manner that the material is split into finer structures after forming the fibrous prestructure. The present invention also relates to a method for manufacturing a fiber comprising at least one self-organized polymer, with the method comprises the following steps: Preparing a spinning solution comprising at least one organic solvent and at least one self-organized polymer, and spinning the self-organized polymer into the fiber by an electrostatic spinning method in such a manner that the spinning solution is fed through a capillary (2) having a first potential towards a receiving area (5) having a second potential. The nano-domains in the fiber are controlled after the self-organized structure is formed. The present invention also relates to a fibrous structure, which has free space between fibers forming a network. The free space include fibers formed of at least one self-organized polymer.
