## Description

- description: Recently, mechanochromic soft materials that enable smart sensing functions
    by visual inspection without the need for special devices have been attracting
    attention. We have developed a non-close-packed type elastic colloidal crystal
    sheet through a simple shear-induced process. The colloidal crystal state, in
    which the (111) plane exhibited significant orientation due to shear stress, was
    successfully stabilized in the 4-hydroxybutyl acrylate (4-HBA) monomer precursor
    dispersed with desalted silica colloidal particles through the implementation
    of UV irradiation radical polymerization. Consequently, a solid colloidal crystal
    sheet was produced, capable of reversibly modulating its structural color in response
    to elastic deformation. In this article report will address the stress response
    functions of this sheet due to elastic deformation of stretching, compressing
    and bending. In addition, a rapid structural color change at 4.17 ms unit by impacting.
    By analysis of tensile and strain curve, Young’s module was 0.56 MPa, tensile
    strength 0.73 MPa and elongation brake was 142.9%. In addition, durability repeating
    elongating the rubber sheet for 100,000 times.  Up now 150 cm2 sheet produced
    by hand made batch process. This simple process is suitable for scaling up colloidal
    crystal to mass production and is expected to have a wide range of engineering
    applications with mechanochromic materials.
