摘要: It is not a simple task to measure contact angle of water drop on superhydrophobic surface with sessile method, because roll-off very low. Usually measured by fixing intentional defects the or needle. We examined effects size and measuring condition such as use needle static measurement surface. Results showed that angles remain almost constant within intrinsic errors unless there wetting transition during measurement. expect this study will provide deeper understanding nature convenient
