1. Surface Properties of Fluorinated and Semifluorinated Alkanes Mesfin Tsige, Department of Physics, Southern Illinois University, Carbondale, IL 62901
Surface Tension: Simulation results for bulk density
and surface tension of short perfluorinated alkanes
(C6F14 to C10F22) as a function of temperature using
two different forcefields are shown below.
Liquid-Liquid Interfaces: The figure below
shows liquid-liquid interfacial behavior of
Semifluorinated (SFA) alkane diblock copolymer
with water(left) and with alkane (right).
In contrast to the sharp interfaces between
SFA and water, SFAs are found to be miscible
with alkanes and perfluorinated alkanes.
The computed liquid densities and surface tension from
both models are in excellent agreement with experiment
Our next goal will be to extend the investigation to long fluorinated and
Semifluorinated alkanes.
