Here, a fluorine-free robust superhydrophobic coating was fabricated on the Al alloy substrate by simple and low-cost approach. Embed modified TiO2 nanoparticles onto semi-cured epoxy resin adhesive layer prominently reduces content of low-energy materials (stearic acid) coating. This prepared with hierarchical structures, re-entrant structures low surface energy shows superhydrophobic. The exc...

Superhydrophobic (SH) property is a naturally occurring phenomenon that has wide range of potential applications such as antiicing, anticorrosion, electrowetting, blood typing, and so forth, therefore, inspires the researchers to mimic them over artificial surfaces achieve desired properties. Low surface energy suitable roughness are two key factors play vital role in developing SH surfaces. He...

background: titanium dioxide (tio2)-mediated photocatalysis has been found to be an efficient method of water treatment and is capable of degrading a wide range of organic pollutants and microbial agents with high efficiency. the microorganism pseudomonas aeruginosa is resistant to chemicals and uv irradiation. bacteria which are resistant to uv-induced oxidative damage of the cell membrane are...

The modern rhythm of human life leads to well-known problems, which are air, water and soil pollution climate warming. An increase in the power industries vehicles not only atmospheric by-products incomplete fuel combustion but also various microscopic particles that form aerosols, carry an obvious danger health pollute buildings’ facades. environmentally friendly building material with a hybri...

The self-cleaning function of superhydrophobic surfaces is conventionally attributed to the removal of contaminating particles by impacting or rolling water droplets, which implies the action of external forces such as gravity. Here, we demonstrate a unique self-cleaning mechanism whereby the contaminated superhydrophobic surface is exposed to condensing water vapor, and the contaminants are au...

Photocatalytic technology is considered as one of the most attractive and promising technologies to directly harvest, convert store renewable solar energy for generating sustainable green a broad range environmental applications. However, use photocatalyst in powder or coating forms restricts its applications due disadvantages, such difficulty recovery nano-powder, secondary pollution, low adhe...

We report that hydrophilic polyurethane mushroom shaped microfiber arrays possess wet self-cleaning ability using the lotus effect as biologically inspired synthetic fibrillar adhesives. In comparison with a flat surface made of the same polyurethane, the fiber array exhibited almost 100% wet self-cleaning without any degradation of adhesive strength. We attribute this cleaning ability to the m...
