Semi-transparent heat insulation coatings are an essential next-generation green technology. In this study, we report the synthesis of conducting polymer PAni:PSS particles with different acid dopant for metal-free near-infrared (NIR) shielding material by controlling the chemical composition without adding any chemicals and applying extra treatment. A PAni:PSS particles were polymerized via oxidative polymerization, using the series of different acid dopant, such as Sulfuric acid (H2SO4), Perchloric acid (HClO4), Hydrochloric acid (HCl) and Naphthalenesulfonic acid (NSA). The maximum NIR-shielding efficiency of the film was 90% with 60% transmittance. This powerful NIR shielding performance of PAni:PSS make it an ideal candidate for heat-insulating materials that find application in semi-transparent heat-insulator-coated windows. |
