Featured R&D 100 Award Winner: Contaminant Adhesion Mitigating Epoxy Composite Coatings for Aeronautic Environments

By R&D Magazine | April 26, 2017

This Contaminant Adhesion Mitigating Epoxy Composite Coatings for Aeronautic Environments, developed by NASA Langley Research Center, is a copolymeric epoxy coating that is loaded with a fluorinated aliphatic chemical species and nano- to microscale particle fillers. The coating, which won a 2016 R&D 100 award, was developed as a hydrophobic and non-wetting coating for aerodynamic surfaces to prevent accumulation of insect strike remains that can lead to natural laminar flow disruption and aerodynamic inefficiencies. The coating achieves hydrophobicity in two ways. First, the fluorinated aliphatic chemical species are hydrophobic surface modification additives that preferentially migrate to the polymer surface that is exposed to air. Secondly, the incorporation of particle fillers produces a micro-textured surface that displays excellent resistance to wetting. Combined, these two factors increase hydrophobicity and can also be used to readily generate superhydrophobic surfaces. is a copolymeric epoxy coating that is loaded with a fluorinated aliphatic chemical species and nano- to microscale particle fillers.
