Résumé : |
New thermal pigments can change temperature to keep items formulated with them cool by reflecting heat, say the author. Developments in the pigments sector have led to the emergence of thermal pigments which change temperature by reflecting heat. These complex inorganic colour pigments (CICPs) are designed to keep items formulated with them cooler. CICPS appear in some of the same colour ranges as conventional pigments, but are highly reflective in the infrared portion of the solar spectrum. The electromagnetic radiation from the sun, striking the Earth, consists of radiation in the wavelengths of about 300 nanometers (nm) to 2500 nanometers. The wevelength region below 400 nanometers is called the ultraviolet (UV). The UV region can cause damage to our bodies and skin, and also causes degradation to paints and polymers. The visible region, 400 to 700 nanometers, is the area where our eyes are attuned to see light in all its various colours. The final area from 700 to 2500 nanometers is the infrared (IR) region. These longer infrared wavelengths are invisible to the eye, yet contain about half of the solar energy which strikes the earth. |
