FLUID COLLOID CRYSTAL AND PROCESS FOR PRODUCING THREE-DIMENSIONAL ALIGNED PARTICLE MASS THEREFROM

摘要

PROBLEM TO BE SOLVED: To provide a new fluid colloidal crystalline material which is a non-dried material-based fluid colloidal particle-conformed material formed by the spherical fine particles of colloidal particle-sized organic or inorganic polymer in a solid-liquid colloidal dispersion system, having characteristic of exhibiting an excellent reflection characteristic spectrum to irradiated visible light, ultraviolet light and infrared light.;SOLUTION: This fluid colloidal crystalline material is the solid-liquid dispersion under an electric charge of ≤2,000 μS/cm electric conductivity, of a dispersion medium solution of an aqueous or dissolvable water-containing non-aqueous system having 70 % dispersion concentration of dispersoid of the electric charging spherical colloidal particles of organic or inorganic polymer having less than several μm mean particle diameter (d). Around the dispersoid, an electric double layer having a thickness (Δe) is present. The distance between particles (L) expressed by a distance between the centers of particles opposing in central line direction each other satisfies a relationship: (d)(L)≤(d)+2(Δe). The solid-liquid dispersion forms a 3-dimensional colloidal particle-conformed material exhibiting fluidity as a particle-arranged structural material conforming as a lattice state in vertical and horizontal directions.;COPYRIGHT: (C)2005,JPO&NCIPI
