Abstract
The objective of this study was to synthesize, characterize and evaluate the nanomaterials-based superhydrophobic (super water-repellent) coatings on Portland cement concrete (PCC) surfaces. These coatings are synthesized with nanomaterials such as polytetrafluoroethylene (PTFE), polyether ether ketone (PEEK) and silanized diatomaceous earth (DE). Using layer-by-layer (LBL) deposition technique, each coating type was deposited at four different spray durations. The water-repellency of the coated surfaces were characterized by measuring static water contact angles (WCAs). These measurements were evaluated through a statistical design-based experimental test program which revealed that the spray duration and coating type are significant variables. A skid-resistant coating composed of PTFE and PEEK was utilized to evaluate the impact of superhydrophobic coatings on pavement skid resistance.
