Effects and origins of slip in micro- and nanoscopic polymer flows

摘要

The slip length of polystyrene dewetting from self-assembled monolayers (SAMs) is found to depend on the type of molecule composing the SAM, as well as on the specific composition of the SAM when containing a mixture of chemically identical OTS and DTS molecules. This observation indicates that slip is highly dependent on molecular details of the SAM; the slip length may be controlled over at least one order of magnitude by tuning the composition of the SAM.
