| 논문초록 | In recent times, LiDAR technology has become integral to autonomous vehicles, utilizing near-infrared (NIR) laser emissions to measure distances and object structures via reflected light. However, prevalent dark-tone pigments, primarily carbon black-based, absorb both visible and NIR light, hindering LiDAR detection. To address this, we engineered a bilayer dark-tone paint structure capable of NIR reflection. Through novel diketopyrrolopyrrole (DPP) derivative synthesis and blending with yellow and blue organic pigments, we achieved effective NIR penetration while maintaining visible light absorption. Under optimized conditions (Br-phenyl-DPP:Yellow151:CuPc=1:1:3), we produced a black pigment (L*=27.0, a*=-0.03, b*=0.35) exhibiting NIR reflectivity of 58.07% and excellent UV resistance (ΔE=0.29). This breakthrough holds promise for dark-tone pigments suitable for LiDAR applications. |
