| Research Abstract |
Solubilities of disperse dyes in supercritical carbon dioxide and diffusion coefficients of disperse dyes to polymer in supercritical carbon dioxide were measured and correlated by thermodynamic models. Molecular simulation for diffusion coefficients in supercritical fluids were carried out. The temperature and pressure dependences of solubility were clarified and the activation energy of diffusion to polymer in supercritical carbon dioxide was estimated. The method for mutual diffusivity by non-equilibrium molecular dynamics was proposed.
