Abstract: On soaking the ultrathin polyamine capsules in bis-(2-ethyl) phosphate (Abbraviated P204), we prepared the functional capsules with P204 in the porous film. P204 in the pores of the capsule wall existed in the form of bilayer structure. It acted as a prohibitor to the permeation of core material KCl and the permeable efficiency was decreased remarkbly. When we added Ca~(2+) to the external water phase, the hydrophilic headgroup of P204 reacted with Ca~(2+), and the multibilayer order was spoiled. The permeable efficiency was increased. On treating with EDTA Ca~(2+) reacted with EDTA, the permeable efficiency recovered its original value. Moreover, if the capsules were put in an electric field, the permeable efficiency was increased because the multibilayer order was spoiled with the orientation of the hydrophilic headgroup. On removing the electric field, the permeable efficiency recovered its original value. Therefore, the capsules with P204 have reversible functional permeation controlled by chemical reaction and electric field.
