Abstract
Although the diffusion coefficients of dyes in PDMS-based elastomers (FK-001 and FK-002) with solvent dispersibility and thermoplastic are smaller than those of conventional PDMS (KE-1606), about 1/42∼1/72, the increase in diffusion coefficient with temperature of PDMS is linear, while that of PDMS-based elastomers is non-linear. FK-001 showed the rate of increase of diffusion coefficient from 25°C to 40°C was about 1/4 smaller than that of KE-1606, but the rate of increase from 40°C to 55°C was about 2.9 times larger than that of KE-1606. In the future, it is expected that this elastomer will be improved by focusing on the diffusion characteristics of dyes and applied to the control of dye circulation by temperature at the interface between this elastomer and PDMS.
