More Information
Summary:A ultraviolet and infrared absorbing polyvinyl butyral film is disclosed which is comprised of copper chalcogenide nanoparticles and oxide nanoparticles. The polyvinyl butyral film has a visible transmittance greater than 75%, at least 50% absorption between 780 and 1400 nm, around 100% absorption beyond 1400 nm, and at least 85% absorption in the UV region. Also disclosed is a laminate comprising one or more substrates, a polymeric matrix disposed on or between the one or more substrates, and copper chalcogenide nanoparticles dispersed in the polymeric matrix. The laminate has a visible transmittance greater than 75%, at least 50% absorption between 780 and 1400 nm, around 100% absorption beyond 1400 nm, and at least 85% absorption in the UV region
