Superhydrophobic photothermal graphene composites and their functional applications in microrobots swimming at the air/water interface

Photoresponsive superhydrophobic microrobots based on Marangoni effect are attracting more and more attention. Graphene has high photothermal properties and nanostructures. It is an excellent material for manufacturing superhydrophobic microrobots moving at the air/water interface. However, it is difficult to fabricate superhydrophobic microrobots with complex shapes moving at the air/water interface using graphene without chemical modification....
