“…[28][29][30][31] For example, light-trapping structures can be used to enhance the surface sunlight absorption and the efficiency of a solar evaporator is maximized accordingly. [27,32,33] Moreover, lightweight foams with superhydrophobicity have gained significant attention for their potential applications in self-cleaning, antifouling, anti-corrosion, anti-icing, and so on, although durability is one of the major issues limiting their practical application. [34][35][36][37] Combining the surface micro/nanostructures and superhydrophobic polymer foam is an attractive and facile approach to address the gap between state-of-art and practical applications in solar evaporation.…”

Solar evaporation is one of the most attractive and sustainable approaches to address worldwide freshwater scarcity. Unfortunately, it is still a crucial challenge that needs to be confronted when the solar evaporator faces harsh application environments. Herein, a promising polymer molding method that combines melt blending and compression molding, namely micro extrusion compression molding, is proposed for the cost‐effective fabrication of lightweight polyethylene/graphene nanosheets (PE/GNs) foam with interconnected vapor escape channels and surface micro‐nanostructures. A contact angle of 155 ± 2°, a rolling angle of 5 ± 1° and reflectance of ≈1.6% in the wavelength range of 300–2500 nm appears on the micro‐nanostructured PE/GNs foam surface. More interestingly, the micro‐nanostructured PE/GNs foam surface can maintain a robust superhydrophobic state under dynamic impacting, high temperature and acid‐/alkali solutions. These results mean that the micro‐nanostructured PE/GNs foam surface possesses self‐cleaning, anti‐icing and photothermal deicing properties at the same time. Importantly, the foam exhibits an evaporation rate of 1.83 kg m−2 h−1 under 1 Sun illumination and excellent salt rejecting performance when it is used as a self‐floating solar evaporator. The proposed method provides an ideal and industrialized approach for the mass production of solar evaporators suitable for practical application environments.

“…In recent years, functional surface technologies have been developed in many fields, such as superhydrophobic surfaces [16], trapped light structured surfaces [17], antibacterial surfaces [18], and anticorrosion surfaces [19], where the derived liquid self-driven technologies have gradually attracted great attention from related researchers. The wedge-patterned functional surface prepared by Deng et al [20] enables the motion control of a single droplet.…”

In order to improve the starved lubrication condition of rolling bearings, three kinds of textures, namely dimple, groove texture, and gradient groove texture, were developed on the guiding surface of thrust ball bearings in this study. The results show that gradient groove texture has the one-way self-driving function of liquid droplets. The root mean square (RMS) value of vibration acceleration of gradient groove textured bearing (GGB) decreased by 49.1% and the kurtosis decreased by 24.6% compared with non-textured bearing (NB) due to the directional spreading effect of gradient groove textures on oil. The frequency domain analysis showed that the textures mainly suppressed the medium and high-frequency energy of bearing vibration, and the GGB was reduced the most with 65.3% and 48%, respectively. In addition, whether the grease is sufficiently sheared has a large impact on the oil guiding effect, and the friction torque of GGB could decrease by 10.5% compared with NB in the sufficiently sheared condition. Therefore, the gradient groove texture with oil self-driven effect on the guiding surface of rolling bearing can effectively improve the lubrication condition of the bearing and thus reduce the bearing vibration and friction torque, which has a promising application prospect.
