Liquid–Solid Interface Chemistry in TENGs for Energy Harvesting ⚡π§
Liquid–solid interface chemistry in triboelectric nanogenerators (TENGs) is a fascinating area that bridges surface science, electrochemistry, and energy harvesting ⚡π¬. At the heart of TENG operation lies the interaction between liquid molecules and solid surfaces, where charge transfer occurs through contact electrification. Factors such as surface roughness, functional groups, wettability, and ionic concentration significantly influence the efficiency of charge generation π§. Understanding these interfacial mechanisms helps researchers optimize materials and enhance the electrical output of TENG systems. The structural design of liquid–solid interfaces plays a crucial role in improving performance π§ͺ✨. Advanced micro/nanostructured surfaces, hydrophobic coatings, and engineered polymers are widely used to maximize contact area and charge separation. Materials like graphene, metal oxides, and flexible polymers contribute to higher durability and sensitivity π. By tailoring inte...
