Abstract: An aqueous precursor liquid for forming an anti-fouling heterophasic thermoset polymeric coating is provided. The precursor liquid includes a first fluorine-containing polyol precursor having a functionality >about 2 that forms a fluorine-containing polymer component defining a first phase in the coating. The precursor liquid also includes a second precursor that forms a second component present as a second phase. The first phase can be a continuous phase and the second phase can be a discrete phase, or the second phase can be the continuous phase and the first phase can be the discrete phase. The discrete phase includes a plurality of domains each having an average size of ≥to about 500 nm to ≤to about 25,000 nm. A crosslinking agent, water, and optional acid or base are also present. Methods of making anti-fouling heterophasic thermoset polymeric coatings with such precursors are also provided.

Abstract: A system for bacteria irradiation from an occupant zone of a vehicle is provided. The system comprises an interior portion disposed in the occupant zone. The interior portion has one of a predetermined surface porosity and a predetermined surface roughness. The interior portion has phosphorescent paint for visual indication. The system further comprises a high energy visible (HEV) light source integrated within the interior portion. The HEV light source has an emission wavelength of between about 375 nm and about 425 nm. The HEV light source further provides a cumulative energy of between about 1 J/cm2 and about 50 J/cm2. The system further comprises a vehicle processor in communication with the HEV light source. The vehicle processor is configured to enable the HEV light source. The system further comprises a sensor in communication with the vehicle processor and configured to provide input on when to enable light source.

Abstract: A sensor for emitting or receiving light rays includes a clear substrate having a first surface, and an applique attached to the first surface of the clear substrate. The applique includes a transparent fluoropolymer sheet of fluorinated ethylene propylene having a first surface facing the first surface of the clear substrate, and a pressure sensitive optically clear acrylic adhesive disposed on the first surface of the fluoropolymer sheet. The pressure sensitive acrylic adhesive adheres the transparent sheet to the first surface of the clear substrate, and exhibits a peel strength of between 1 and 3 lbs/in. The first surface of the fluoropolymer sheet is treated for adhesion prior to applying the pressure sensitive acrylic adhesive thereto.
