Abstract
We have studied the influence of the boundary surfaces on spinodal dec omposition in thin films of a critical polymer mixture. The wetting la yer formed during spinodal decomposition is found to grow as t1/3 and the corresponding composition vs. depth profiles exhibit dynamic scali ng behavior. For sufficiently thin films, the effects of the two bound ary surfaces interfere and the overall domain structure is found to be strongly thickness dependent.
