“…Moreover, the superhydrophobic self-cleaning phenomenon is caused by the combination of rough micro/nano capillaries and the presence of low-surface-energy wax-like substances . Based on the mechanism, superhydrophobic surfaces have been prepared by either modifying low-surface-energy substances on rough micro/nano surfaces or constructing rough micro/nano structures on the surface of low surface energy substances. , With the support of this rationale, researchers have started to utilize superhydrophobic surfaces from both micro/nano structures with low surface energy to meet the need for characteristic surfaces. − Nano zinc oxide is a multifunctional and environmentally friendly inorganic material, which is widely used in electrical conductivity, thermal conductivity due to its excellent catalytic properties. , Many studies on preparing superhydrophobic surfaces with the modification of nano zinc oxide have gained attention.

Research efforts have intensified on developing superhydrophobic surfaces on concrete structures to limit the damage caused by the natural porosity and hydrophilicity of cementitious materials. However, the feasibility idea is impeded by the complex preparation process and weak adhesion/stability performance. Therefore, superhydrophobic coatings were rapidly prepared on mortar surfaces by a straightforward and effective one-step method using zinc oxide (ZnO) modified with stearic acid and epoxy resin. The microstructure, physical/chemical properties, hydrophobic properties, and stability of the coatings were systematically investigated. The experimental results showed that the water contact angle of the samples reached a maximum value of 164.2° and a sliding angle of 4.6° when the stearic acid content was 0.5 g. The water absorption of the coated superhydrophobic mortar was reduced by approximately 61% compared to that of ordinary mortar, and neither particulate pollutants nor liquid pollutants could contaminate the superhydrophobic mortar. The coating maintained a superhydrophobic state and exhibited good physical durability after sandpaper abrasion, tape peeling, and high-temperature resistance tests. The water cluster diffusion coefficient on surface of the ordinary coating was 0.1645 × 10–4 and 0.0328 × 10–4 cm2/s on surface of the modified coating after molecular dynamics simulation.
