Influence of substrate treatment on self-organized pattern formation by langmuir-blodgett transfer.
Mesoscopic stripe patterns can be obtained by Langmuir-Blodgett (LB) transfer of l-alpha-dipalmitoylphosphatidylcholine (DPPC) onto solid substrates. In order to investigate the influence of substrates on the pattern formation, silicon slides treated by different cleaning processes were taken as model systems. A shift in the transfer pressure range for patterning was observed between plasma- and RCA-treated silicon. This can be explained with a model of equivalent states and taking into account the influence of microscale water films on the substrates.
