Research Abstract

By tracking the diffusive motions of individual guest dyes embedded in materials, we have evaluated microscopic property change in polymer-based reactive materials. Application of the method revealed the hierarchical mobility change of guest dyes in a thermoreactive material under the network formation. We have also evaluated a photo-curable polymeric material at various stages of network formation.
