In this work, the drag reduction (DR) performance of superhydrophobic composite coatings was investigated. The DR behavior for both short-term and long-term use studied using a parallel-plate rheometer, morphology interface by fluorescence staining. For performance, increased with higher silica NP content in composition up to 40% weight. played governing role except very high particle loading sample. surface topography effect on also studied. increase autocorrelation length found be related...

The performance of hydrophobic surfaces under hydraulic pressures is critical to a wide range practical applications such as drag reduction seaboard vessels and design microfluidic devices. This research focuses on the evaluation velocity slip coatings external hydrostatic using an acoustic wave device (i.e., quartz crystal microbalance, QCM). correlation between resonant frequency shift QCM surface coated was theoretically developed model validated by comparing measurement results...

A durable superhydrophobic coating formulation with epoxy binder thermoset was used to coat on surfaces, which provide high quality for corrosion protection, reduced biofouling and improved hydrodynamic behavior. The single double layers of these nanostructured were fabricated coated a novel quartz crystal microbalance (QCM) technique investigate their hydrophobic properties. Different static dynamic wettability obtained characterized by evaluating the electrical impedance QCM in air DI...
