Electrospun Microfibrous Porous Stretchable Membranes And The Method

Electrospun Microfibrous Porous Stretchable Membranes And The Method Of Preparation Thereof

Abstract: The present invention discloses a highly stretchable matrix, comprising mesh of lattice structures of microfibrillar filaments, having pore size enlargeable up to 8 times by moving the microfibrillar filaments perpendicular to the longitudinal axis of the microfibrillar filaments without losing its integrity. The invention also pertains to a method of preparing said highly stretchable matrix comprising the steps of: electrostatic spinning of the polymeric solution as microfibers, creating an air-flow at the inter-phase of microfibers to completely eliminate the solvent from the surface of the microfibers bundles to avoid inter-fibrillar bonding after collection and dispersing the microfibers in a direction perpendicular to the longitudinal axis of the fibers, 6 -12 times the original width using a dispersion unit to obtain a stretch responsive fibrillar matrix.
