A sustainable, reliable and self-powered anti-corrosion method for metallic structures is the key to improve the operation stability and service life of equipment. In this work, a series of durable...

Construction of durable superhydrophobic and anti-icing coatings via incorporating boroxine cross-linked silicone elastomers with good self-healability

“…Using materials that are naturally abrasion-resistant and stable hydrophobic to prevent damage to the micro-nano surface and chemistry or adding an elastic/soft composition to the coating layer to fend off mechanical damage by dispersing energy with deformation has been the most popular method for creating long-lasting superhydrophobicity. [13][14][15][16] K. Maghsoudi fabricated superhydrophobic silicone rubber surfaces via two methods, micro-compression molding and atmospheric-pressure plasma treatment, which maintained a water contact angle of 41501 under harsh environmental conditions. And when the superhydrophobic surface was impacted at a flow rate of 1 mL min À1 , the contact angle was still above 1501 after 6000 s. 17 However, these elastic/soft compositions are often composed of covalent bonds, which have poor energy dissipation capability and cannot be repaired when damaged.…”

Design of an interface heating device based on polydivinylbenzene/SiO2/Bi2WO6and its visible light response performance for water purification

“…The structure of the devices needs to be optimized when solar desalination devices are used to treat sewage discharged from chemical plants and the textile industry. Superhydrophobic materials show an efficient oil–water separation capacity for the non-water-soluble oily wastewater discharged from chemical plants, 13–15 which are used in the field of durable coatings, 16,17 vapor escape channels, 18 anti-reflective 19 self-powered cathodic protection, 20 oil/water separation 21,22 and self-cleaning. 23 Ma et al 24 obtained the superhydrophobic polystyrene/SiO 2 fabric with a contact angle of 153° using the waste polystyrene solubilization technology and achieved oil–water separation.…”

LEGO-block-inspired versatile triboelectric nanogenerators as power cells to harvest vibration energy

“…To obtain the mechanical shock output response, spring-assisted structures are typically used to convert lowfrequency mechanical shocks into high-frequency vibrations to improve energy conversion efficiency. [18][19][20][21] TENGs of various shapes, such as spherical, [22][23][24][25] circular arc shape, 26,27 disk honeycomb shape, 28 and cuboid, [29][30][31][32] have been designed for various energy harvesting scenarios. However, adding springs results in a complex TENG structure, high failure rate, difficult maintenance, and low space utilization rate.…”
