Effects of Compression and Shearing on the Microstructure of Polymer-Immobilized Non-Close-Packed Colloidal Crystalline Arrays
journal contribution
posted on 2005-12-06, 00:00 authored by Hiroshi Nakamura, Masahiko IshiiWe have examined the changes in the optical properties and microstructure of polymer-immobilized
non-close-packed colloidal crystalline arrays with compression and shearing stress. The optical properties
and microstructures of the arrays were measured by angle-resolved reflection spectroscopy. The spectra
indicate an increase in the refractive index and a decrease in the interplane spacing with compression,
however, indicating an increase in the interplane spacing with shearing stress. These results show that
compression decreases the interplane spacing without moving the inner-plane position, while shearing
stress increases the interplane spacing by moving the position of the spheres in the same plane.
