The Adsorbed Film Structure of End-Functionalized Poly (perfluoro-n-propylene oxide)

The D-4OH adsorbed film structure is investigated as a function of film thickness and of molecular weight via surface energy measurements, terraced flow profiles, and ellipsometric imaging for film dewetting. The D-4OH monolayer thickness on a carbon surface exhibited a power law dependence on molec...
