Frequency Selective Surface for High-Performance Solar Coatings for Reduced Energy Consumption in Buildings
- Detailed Technology Description
- TechnologyDr. Toor at the University of Iowa has developed flexible solar control filmswith low-cost copper-based metallic nanostructures to enable high UV and IRreflection. This wavelength selective behavior of the solarcontrol films reduces cooling costs during the summer time, without interferingwith wireless and other electronic signals. Additionally, solar control films developedwith copper-based metallic nanostructures surpass existing solutions in termsof cost/performance, and directly result in reduced energy usage bybuildings. AdvantagesHelp reduce cooling costs during the summer time in residential and commercial buildingsIndustrial scale manufacturingCost competitive (<$12/m2)Reflects 80% of UV (λ= 300-450 nm), 95% of IR (λ= 850-1000 nm), and transmits 95% of visible light (λ= 450-850 nm)Can be installed as retrofit on windows, tents and other building structures

Background
State-of-the-art commercially available solarcontrol films constitute a multilayer stack consisting of a hard coat layer, aninfrared(IR) light-absorbing nanoparticle layer, an IRlight-reflecting multilayer film, a pressure sensitive adhesive layer, and anoptical substrate. These multilayersolar control films are costly (~$13/m2-$40/m2) and difficult tomanufacture. The nanoparticles in IRdyes in the multilayer film are also IR absorbing, and this absorption resultsin heat gain that can cause delamination. These films can be used in residential and commercial buildings, as wellas other applications.
