The effect of boundary surfaces on phase separation and microphase separation in binary polymer blends and block copolymers respectively, has gained increasing attention over the last 5 years. It has been realized that the complex interplay between wetting and phase separation may severely influence the phase separation process thereby leading to near-surface domain structures, which differ distinctly from the respective bulk morphologies. In the present article, we try to summarize the basic...The effect of boundary surfaces on phase separation and microphase separation in binary polymer blends and block copolymers respectively, has gained increasing attention over the last 5 years. It has been realized that the complex interplay between wetting and phase separation may severely influence the phase separation process thereby leading to near-surface domain structures, which differ distinctly from the respective bulk morphologies. In the present article, we try to summarize the basic features of surface directed (micro-) phase separation in immiscible polymer systems. For both polymer blends and block copolymers a brief review of the historical development is given, followed by a list of selected examples representing the large number of current research activities in these fields. Particular attention is given to the possibility to actively control the domain morphologies via surface interactions in view of possible technological applications.» weiterlesen» einklappen
