Abstract
An anisotropic material by molecular alignment has been attracted for its wide applicability. Molecular alignment control and immobilization techniques enable us to design new anisotropic materials. In order to promote and realize the anisotropic material processing, development of the real-time measuring technique as a feedback sensor is inevitable. Forced Rayleigh scattering method (FRSM) is a measurement technique for in-plane thermal diffusivity, and some characteristics (noncontact, high-speed and micro-scale) indicate the ability for a real-time sensing of anisotropic heat conduction. In this study, we controlled molecular alignment of "UV curable liquid crystal" by electric field and immobilization by UV light. Then we measured anisotropic thermal diffusivity by FRSM.
