Kinetics of light scattering in an epoxy resin suspension of carbon microparticles
Abstract
The relaxation kinetics of laser-induced scattering and absorption was investigated in a liquid epoxy resin suspension of carbon microparticles. The scattered light intensity and the optical transmittance at temperatures below +10°C demonstrate anomalous kinetics with a distinct build-up stage. The observed behavior is interpreted as a manifestation of processes of mechanical stress relaxation in epoxy layers around microbubbles. The microbubbles induced by laser irradiation of the suspension can be a tool for the investigation of mechanical stress relaxation in polymers.
