Paper Abstract

Commonly, one dimensional construct has a restriction of viewing angle. We report a new, simplistic strategy to Particle Photonic Crystal: an ellipsoidal block copolymer nanoparticles. It has a wider viewing angle and is easier to make. We made a particle of photonic crystal based on Poly Styrene-block-Poly-2-Vinyl Pyridine(PS-b-P2VP) in chloroform. After using Poly Vinyl Alcohol(PVA), it was in state of emulsion and self assembly method followed afterwards. In the first trial, we observed particle structure variation according to the difference in molecular weight such as 52k-57k, 75k-66.5k, 102k-97k. Afterwards, we exhibited how particle structure change by the addition of swelling solution (Alcohol). The molecular structure of particle photonic crystal was investigated by Transmission Electron Microscope. The color was measured by color-difference meter.
