“…Polyphenols, with di/tri hydroxyphenyl as the most basic expression structure, are ubiquitous in natural plants and marine organisms and come in many varieties. 32–34 Typical polyphenols are represented by polydopamine (PDA), tannic acid (TA), and gallic acid (GA), 35–37 and also include tea polyphenols, laccase, plant flavonoids, etc ., 38–40 which have many distinct properties such as hydrophilicity, 41 adhesion, 42,43 secondary reactivity, 44 photothermal property, 45,46 etc . These excellent properties endow polyphenol-based photothermal materials with many advantages to environmentally develop high-performance PIES, and more and more relevant and important studies have been reported most recently, leading the next hotspot and frontier.…”
