Abstract
A thermochromic, near infrared (NIR) absorbing interlayer. The interlayer includes a NIR-absorbing substance dispersed or dissolved in a polymer matrix and a thermochromic material or system. The interlayer has an internal visible light transmission above 50% and an internal solar energy transmission below 55% when the interlayer is at 15° C. and an internal visible light transmission below 20% and an internal solar energy transmission below 20% when the interlayer is at 75° C. The internal haze of the interlayer is below 3.5%.
Claims56
A thermochromic, near infrared (NIR) absorbing interlayer comprising:
- NIR-absorbing substance dispersed or dissolved in a polymer matrix;
- and
- a thermochromic material or system;
- wherein the interlayer has an internal visible light transmission above 50% and an internal solar energy transmission below 55% when the interlayer is at 15° C. and an internal visible light transmission below 20% and an internal solar energy transmission below 20% when the interlayer is at 75° C., and wherein the internal haze of the interlayer is below 3.5%.
A laminate comprising:
- an interlayer comprising an NIR-absorbing substance dispersed or dissolved in a polymer matrix;
- a first sheet of plastic or glass;
- and
- a second sheet of plastic or glass;
- wherein the interlayer is bonded between the first sheet and the second sheet, wherein at least one of the first sheet and the second sheet is coated with a low-e coating, and wherein at the laminate has a visible light transmission above 70% and a total solar transmission below 35%.
A laminate comprising:
- an interlayer comprising an NIR-absorbing substance dispersed or dissolved in a polymer matrix and a thermochromic material or system;
- a first sheet of heat strengthened glass;
- and
- a second sheet of heat strengthened glass;
- wherein the interlayer is bonded between the first sheet and the second sheet.
