Contamination-resistant coated substrates

摘要

A coated substrate is claimed. The coating, disposed on the substrate, comprises a self-assembled film having at least one bilayer. Each bilayer comprises a polyanion electrolyte layer and a polycation electrolyte layer. The uppermost layer or exposed layer of the coating comprises a fluoroalkyl group. Each bilayer thickness ranges from about 0.1 nanometers to about 20 nanometers. The resulting coated substrate has a low surface energy and is hydrophobic and/or oleophobic.
