抄録

We perform simulations for thin polymer blend films using the dynamic density functional method. We include the effect of wall-polymer interfacial potentials, and also represent the free interface (polymer-air interface) using void. At the initial stage of our simulations, there already exist three kinds of phase separations, which are wall-induced phase separations, phase separations induced by free surface, and phase separations of bulk. We can find the computational results of layered structures of phase separations near both free and wall interfaces. As the time steps of simulations are evolved, domain width is grown. Density profiles are changed as spinodal waves originating from both free and wall interfaces. Furthermore, at the free interface, we can find the surface roughing induced by domain growth, and the roughness is changed as time evolutions.
