AI Technical Summary
Improving the photothermal performance of existing organic photothermal materials is difficult to control, and structural modifications are costly and time-consuming, limiting their development in the field of photothermal materials.
By employing a random copolymerization strategy, 4,8-bis(5-bromo-4-(2-octyldodecyl)thienyl)-benzodithiadiazole was introduced as a regulating unit and reacted with 4,7-bis(bromo-ethylhexylthienyl-2-)-bisfluoro-benzodithiadiazole and 5,5-bis(trimethyltin)dithiophene via Stille coupling to obtain a random copolymer with a DA-type cross-conjugated structure. The surface of the copolymer was then coated by suspension polymerization to form a high-performance polymer photothermal material.
It significantly improves the upper limit of the material's photothermal performance to 350℃, reduces R&D costs and time, has a simple process, readily available raw materials, and is suitable for applications in multiple fields.
