An Anti-reflective and Anti-Soiling Coating for Glass
ARL Designs LLC, NJ, United States
ARL Designs has developed a unique process for the fabrication of a low-cost, anti-reflective, self-cleaning superhydrophobic coating for glass. Results demonstrate high optical transmission, low-angular dependence of transmission properties, mechanical and chemical stability. Technology is available today for prototypes. Scale-up for manufacturing will use currently available tools.
Primary Application Area: Energy & Efficiency
Technology Development Status: Prototype
Technology Readiness Level: TRL 4
FIGURES OF MERIT
Value Proposition: Coatings produced by ARL Designs will increase the electrical harvest of PV arrays and ensure the safe operation of camera systems. The low-cost fabrication process can be implemented by glass producers, as well as manufactures that use glass, to produce surfaces that are anti-soiling, anti-icing and anti-reflective.

GOVT/EXTERNAL FUNDING SOURCES
Government Funding/Support to Date: ARL Designs has been awarded a prestigious National Science Foundation Small Business Innovation Research Grant; phase I and II totaling roughly $1M. Entitled “Scratch and Abrasion Resistant Superhydrophobic Polymer Coatings”, Phase I (Award#:1215288) was received 7/1/2012 and Phase II (Award#:1330949) began 9/1/2013. The team’s R&D activities have shown that control of surface roughness can be used to fabricate surfaces on which water slips off the surface at low tilt angles (i.e. low slip angles) yet the surfaces remain superhydrophobic after being subjected to mechanical abrasion. A model was developed to explain these results. Correlations of polymer structure on mechanical stability were also developed. This knowledge is being paired with high speed fabrication techniques.
