Self-Organized Hierarchy Structures Composed of Honeycomb-Like Polymer Films and Spider-Web-Like Particle Structures

Abstract

We demonstrate a self-organized system for fabricating a hierarchical structure, composed of a honeycomb-like polymer film and the dissipative structures of fine particles. The process is quite simple: Fine-particle water suspension was dropped on polymer organic solution under the exposure of humid air. The cracking of self-assembled particle dissipative structures caused the locally elongation of the honeycomb-like polymer film, and formed hierarchy structures in an one-step procedure.
