Abstract
In this paper, humidity effects on the relaxation of perfluoropolyether (PFPE) films were examined by bonded fraction and surface energy measurements. MD simulation with a bead-spring model was also performed. The calculated relaxation time for a functional PFPE molecule in the film was found to be shorter at high humidity, which is consistent with the experimental results.
