Infrared reflecting films for solar control and other uses

摘要

Solar control films containing a visible light-transmissive flexible support, a first nucleating oxide seed layer, a first metal layer, an organic spacing layer, a second nucleating oxide seed layer, a second metal layer and a polymeric protective layer. The thicknesses of the metal layers and spacing layer are such that the films are visible light-transmissive and infrared-reflective. The films have high visible light transmittance, high Reflected Energy and low Total Solar Heat Transmission.

主权项

1. A solar control film comprising in sequence at least a visible light-transmissive flexible support, a first discontinuous nucleating oxide seed layer formed as a series of small islands, a first metal layer, an organic spacing layer, a second nucleating oxide seed layer formed as a series of small islands, a second metal layer and a polymeric protective layer, wherein the seed layers each have a physical thickness greater than 0 and less than 5 nm, the metal layers each have a physical thickness of 5 to 12 nm, and the organic spacing layer has a refractive index of 1.3 to 1.7 and an optical thickness of 75 to 275 nm, further wherein the film is visible light-transmissive and infrared-reflective.
