In this study, we report the synthesis of conducting polymer PEDOT:P(SS-co-S) with different mole ratio of Poly(Styrene Sulfonate) and Styrene for metal-free near-infrared (NIR) shielding material by controlling the chemical composition without adding any chemicals and applying extra treatment. Sun light becomes ultraviolet, visible, from near infrared the energy ratio of 5% ultraviolet, visible 45%, a near infrared 50%. The NIR protection effect is required in the various items were cut off because near infrared, causing the light and thermal aging, adverse effects on the internal skin is very strong light having 50% of the energy of sunlight. The PEDOT:P(SS-co-S) paticles with diameter of ~1000 nm are synthesized by a simple polymerization and ultra-fine particle dispersion technology, and they have strong NIR absorption. |
