Abstract

Photonic crystals fabricated from a diblock copolymer/homopolymer blend are reported. It is shown that large-area, highly reflective, flexible films can be obtained in which the peak reflective wavelength can be tuned simply by altering the percentage of homopolymer in the blend. A fracture surface of a 40 % homopolymer blend is shown in the Figure.
