- •
Superhydrophobic polystyrene and epoxy resin coatings were prepared by using silica/polymer dispersions.
- •
Formation of micro/nano hierarchical surface topographies were demonstrated by SEM, AFM and interferometric techniques.
- •
Coatings displayed water contact angles well above 150° and contact angle hysteresis below 10°.
- •
Coated surfaces obtained were robust, durable and maintained their superhydrophobicity after a year of storage.
- •
Wenzel roughness factor (r) and average surface roughness (Ra) values were determined.
