Xiaoshuang (June) Wei* and Laura C. Bradley* have recently published their paper entitled, Accessing Thin Film Wetting Regimes During Polymer Growth by Initiated Chemical Vapor Deposition, in Langmuir. In this work the researchers investigate the growth of a fluorinated polymer via initiated chemical vapor deposition onto a suite of isotropic and mesogenic liquids with a range of refractive indices. The polymer morphology at fluid interfaces was found to deviate from conformal films predicted by the positive spreading coefficient, and the resulting morphology is attributed to long-range van der Waals interactions during the deposition process.
