HIGHLY STRETCHABLE MATERIAL SHOWING STRETCHABILITY AT LEAST AS GREAT AS INTRINSIC LIMIT OF MATERIAL USING THREE-DIMENSIONAL NANOSTRUCTURE, AND PREPARATION METHOD THEREOF

Document Type and Number:

WIPO Patent Application WO/2013/147389

Kind Code:

A1

Abstract:

The present invention provides a three-dimensional nanostructured porous stretchable polymer and a preparation method thereof, wherein nanopores of 1-2,000 nm having a regular or irregular shape in each axis direction are three-dimensionally connected to each other or are partially connected to each other inside a porous polymer material having a porous three-dimensional nanostructure, a periodic three-dimensional porous nanostructured pattern is formed by the nanopores and the material having a porous nanostructure, and it is possible to implement high stretchability at least as great as the stretching limit of a polymer bulk material through stress dispersion by the three-dimensional porous nanostructured pattern.
