Scientists have made a range of structures that mimic water-repellant surfaces found in nature.
The team, led by Wei Pan at Tsinghua University, Beijing, China, developed a new electrospinning technique that aligns hydrophobic polymer nanofibres as they form from solution by collecting them on a thin silver wire. When they collected the fibres on to a flat surface instead of the wire, the fibres formed in a random arrangement.
