Summary: The fabrication of honeycomb‐patterned films from PEK‐C in a humid atmosphere is reported. Some governing factors, such as the concentrations of the polymer solutions, the atmosphere humidity, and the volatility of the solvents, are tested. Moreover, by using PEK‐C, PLEG, and PPO, the different mechanisms between hydrophilic polymers and hydrophobic polymers on pattern formation are also studied.
Influence of the concentration on water droplet arrangement. Concentration: a) 1 and b) 2 g · L?1.
