Embodiment approach
[0167] According to various embodiments, for example, as described in PCT publication WO2010 / 142019, control circuits or systems may be used with devices or layered compositions comprising conversion materials.
[0168] Other layers that can be incorporated into laminated glass include:
[0169] Infrared blocking layer: One or more layers may contain an infrared (IR) blocking component. Solar control films may comprise multilayer compositions or laminated glass. Alternately, the infrared blocking material may be incorporated into the glass layer, or incorporated into the adhesive layer. The infrared blocking layer can reflect or absorb infrared rays. The reflection of infrared rays can reduce the heat gain of solar radiation in the inner space, while the absorption of infrared rays can increase the temperature of the laminated glass, which is beneficial to speed up the conversion speed of the conversion material. In certain embodiments, one or more infrared blocking compoun...
Embodiment 1
[0185] Example 1: Devices were fabricated with a range of conversion materials (Table 2) and the integrity of the seals compared. PIB, as the first sealer material, was shown to swell somewhat when exposed to the conversion material, likely absorbing some solvent phase from the crosslinked film. Although the rate of absorption is slow, it appears that PIB alone does not provide a suitable long-term seal unless used in conjunction with a secondary seal material.
[0186] Table 2: Conversion materials. The amounts provided are in wt%. Abbreviations: "Texanol", 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate; "RI", dimethyl 2-methylglutarate; "BC" carbonic acid Butylene carbonate; "DES", diethyl succinate. PVB resins used in conversion materials exhibit a range of MW, PVOH and PVA contents. PVB-4 (MW 95-105k, PVOH content 18-21%, PVA content 0-4%); PVB-5 (MW 50-60k, PVOH content 12-16%, PVA content 1-4%); PVB- 6 (MW 250-350k, PVOH content 12-16%, PVA content 6-10%); PVB-8 (M...
Embodiment 2
[0192] Example 2: Membrane contains conversion material and is sealed by PIB first seal material, indicator / trigger material interaction (which marks first seal's failure) detection. The indicator in the active layer is diarylethene chromophore, and the trigger material is epoxy resin material. Sealed films were subjected to mechanical stress, or assembled from incomplete primary seals (applied primary seals that did not completely cover the perimeter of the conversion material), and were observed during or after epoxy curing. Membranes that were manipulated (bent or bent during curing) or not fully sealed showed blue spots in the area of the breached primary seal. The epoxy resin is a two-step curable thermosetting epoxy resin comprising an epoxy resin and an epoxy hardener.
