Tungsten oxide (WO3) may be applied for producing thermal insulation paper. Tungsten oxide is a new material discovered in recent years, which can be used as transparent heat insulation coating. WO3 nanopowder has the best near infrared absorptive capacity. It not only has strong absorption characteristics in the near-infrared region, and has strong transmission characteristics in the visible region, but also in the ultraviolet region it has a strong shielding property. It also has broad application prospects in the field…
