20130288035 | Manufacture of Composite Optical Materials - A polymer opal material comprises a three dimensionally periodic arrangement of core particles in a matrix material and exhibits structural colour via Bragg reflection. IN a process for manufacturing such a material, a sandwich structure is provided, of a precursor composite material held between first and second sandwiching layers. A relative shear strain of at least 10% is imposed on the precursor composite material by curling the sandwich structure around a roller. The shear strain is cycled, in order to promote the formation of the three dimensional periodic arrangement. | 10-31-2013 |
