Near-infrared Shielding Materials

Scattered arrays of plasmonic nanoparticles have been shown to manifest a strong absorption of near-infrared light, and applied recently to solar control filters for automotive and architectural windows.
New near-infrared shielding materials, LaB6 (lanthanum hexaboride) and CWO®︎ (cesium tungsten oxide) with selective and strong near-infrared absorption in the range of 800 to 1200 nm have been developed originally by SMM. These materials diminish near-infrared rays of shorter wavelength which has much of the heat energy in sunlight compared to ITO (tin-doped indium oxide) and ATO (antimony-doped tin oxide).

Transparent Ligft-Heat Conversion Material

Simulated sunlight was irradiated from up above the sample cup containing water as reference or water-based dispersion of CWO®︎, ITO, ATO and Carbon nanoparticles at various concentration. Temperature change after 20-minutes irradiation were measured.

Temperature increase while irradiation was much higher for CWO®︎ due to its high IR-absorbing property. This light-heat conversion effect is remarkable at the region of high visible light transmittance.

Deep-tinting Materials

Deep-tinting materials of SMM enable sophisticated coloring and possess high tinting strength. For example, privacy protection window films for automotive of deep blue and purple coloring can be realized with small addition. In addition, privacy protection IR-shielding films can be obtained by adding SMM deep-tinting materials to IR-shielding materials, such as CWO® and LaB6.
Compared to organic dyes, SMM deep-tinting materials possess much higher durability. Also, base materials with low haze can be realized by SMM deep-tinting materials due to nano-sized dispersion technology.
