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. |
