Session Y18 - Optical Properties.
ORAL session, Friday morning, March 16
Room 307-308, Washington State Convention Center
Self assembled block copolymer structures have been shown to act as photonic band gap materials for visible light. Due to their physical properties these materials also have interesting acoustic properties. We explore photon-phonon interactions in mesostructured concentrated block copolymer solutions with photonic properties using Reyleigh-Brilluoin scattering. The combination of the photonic bandgap from the mesostructure and the physical properties of the component polymers lead to interesting interactions between light and medium. Experimental results probing the dual nature of these materials will be presented and compared to theoretical calculations.
