Abstract:
The near-infrared radiation absorbing masterbatch provided is prepared by melt-extruding a mixture comprising near-infrared radiation absorbing particles and a first polymer. The particles have a near-infrared absorption at a wavelength ranging from 0.7 μm to 2 μm and a far-infrared emissivity equal to or more than 0.85. The near-infrared light radiated by the particles has a wavelength ranging from 2 μm to 22 μm. Accordingly, the product made from the masterbatch, such as the near-infrared radiation absorbing fiber, plate, or film can not only absorb sunlight and store heat, but also radiate far-infrared light. Hence, the product has a thermal effect for keeping the human body warm and can serve as indoor and outdoor heat storing products at the same time.
Abstract:
Provided is a light-absorbing composition, which is prepared by melt-extruding a mixture containing light-absorbing particle agglomerates and a polymer. The light-absorbing particle agglomerates comprises a dispersant and light-absorbing particles capped with the dispersant, and the light-absorbing particle agglomerates dispersed in the light-absorbing composition and have an average particle size ranging from 10 nanometers to 800 nanometers. Accordingly, the light-absorbing composition can effectively absorb near-infrared light and store infrared heat, and thereby providing infrared-absorbing, heat-insulating and heat-storing abilities. Furthermore, a light-absorbing structure made from the light-absorbing composition has good transparency, higher infrared absorbance, light-absorbing and heat-releasing efficiencies, and is thereby beneficial to keep the temperature equilibrium of buildings or vehicles.
