ELASTIC MATERIAL HAVING PERIODIC STRUCTURE WHOSE STRUCTURAL COLOR CHANGES UNDER TENSILE STRESS AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a structural color-changing elastic material which can be applied to various areas including an inexpensive strain sensor of a completely new type that enables easy visual recognition of strain without using any expensive measuring instrument, various functional members such as a fuse element that blocks light transmission and a simple gravimeter, equipment, various toys, etc.;SOLUTION: The structural color-changing elastic material is obtained through a method comprising a step wherein monodispersed particles are spatially and periodically arranged on a substrate, a step wherein an elastic body is filled in gaps between the periodically arranged monodispersed particles, a step wherein the period of the monodispersed particles filled with the elastic body is increased and a step wherein the elastic body is separated from the substrate.;COPYRIGHT: (C)2006,JPO&NCIPI
