| Research Abstract |
In this study, light-induced phase separation phenomena were studied by using photochemical reactions to drive a polymer mixture from the one-phase into the unstable region on the phase diagram. The competition between the phase separation and the reaction was investigated by using laser scanning confocal microscope. The following results were obtained.:
1) Measurements of elastic deformation in photo-reactive multicomponent polymers by using Mach-Zehnder Interferometry.
2) Developments of Computer-Assisted Irradiation (CAI) method for designing polymers with an arbitrary distribution of characteristic length scales in the micrometers range.
3) Designing multiphase polymer materials with hierarchical morphology by using irradiation with a time delay.
4) Synthesis of interpenetrating polymer networks (IPNs) with spatially graded morphology and an arbitrary distribution of characteristic length scales.
With the above-mentioned results, we are able to conclude that multiphase polymer materials with a variety of morphologies can be controlled and designed by using photochemical reactions
