Backbone orientation of adsorbed polydimethylsiloxane

Iwao Soga, Steve Granick

Research output: Contribution to journalArticlepeer-review


The backbone orientation of an adsorbed polymer with respect to a flat solid surface was measured, using infrared spectroscopy in attenuated total reflection (FTIR-ATR), for polydimethylsiloxane (PDMS) adsorbed onto oxidized germanium from dilute solution in cyclohexane at 25.0 °C. From a siloxane stretch, which originates from the main chain of PDMS, the backbone orientation of the adsorbed PDMS was evaluated. Orientational information was the effective parameter to evaluate the adsorbed polymer conformation and the internal structure change of the adsorbed layer.
