反復型複合基質中のペネトラント拡散濃度分布式について

抄録

By an extention of the previous method²⁾ a theoretical study has been made of the concentration distribution for the non-steady state diffusion in repeated laminates. The laminates considered are composed of 2m repeating units of two different substrates 1 and 2. The method to obtain the concentration distribution in a laminate 1-2²⁾ has been extended for a repeated laminate 1-2-1-2…, The treatment has been given for the conditions where the diffusion coefficients are constant and Henry's law is obeyed in each phase.
Several cases have been treated numerically, and the concentration distribution and sorption rate for the laminate were compared respectively with those for homogeneous membranes.
Several methods to evaluate the over-all diffusion coefficient from either the concentration distribution or the sorption rate have been suggested for the laminate system.
