hydrophobic nano paint | Superhydrophobic coating

A superhydrophobic coating is a nanoscopic surface layer that repels water. Droplets hitting this kind of coating can fully rebound in the shape of column or pancake. This image shows highly absorbent filter paper coated with a super-hydrophobic paint developed at University College London.

High Performance Concrete Additives - products

Nov 19, 2020 · They are also known as plasticizers or high-range water reducers (HRWR), reduce water content by 12 to 30 percent and can be added to concrete with a low-to-normal slump and water-cement ratio to make high-slump flowing concrete. Flowing concrete is a highly fluid but workable concrete that can be placed with little or no vibration or compaction.

When and how self-cleaning of superhydrophobic surfaces

Despite the enormous interest in superhydrophobicity for self-cleaning, a clear picture of contaminant removal is missing, in particular, on a single-particle level. Here, we monitor the removal of individual contaminant particles on the micrometer scale by confocal microscopy. We correlate this space- and time-resolved information with measurements of the friction force.

Hydrophobic modification of ultra-high-performance fiber

Superhydrophobic fiber reinforced cementitious materials or superhydrophobic engineered cementitious composites (SECC) combine the concepts of fiber reinforced concrete with superhydrophobic hybridization. ... However, these have been used in other industries for improving the ductility of ceramics, super-fine abrasives, engineered plastics ...

Superhydrophobic Coatings on Asphalt Concrete Surfaces

However, the ice and water repellency of PTFE has not been evaluated on asphalt concrete. After super-water-repellent (superhydrophobic) materials are applied on a pavement surface, skid resistance must be controlled. The main aim of applying these materials on paved areas is to curb the formation of ice or snow or to facilitate their removal.

Superhydrophobic coatings on Portland cement concrete

Jun 15, 2017 · The objective of this study was to synthesize, characterize and evaluate the nanomaterials-based superhydrophobic (super water-repellent) coatings on Portland cement concrete (PCC) surfaces. These coatings are synthesized with nanomaterials such as polytetrafluoroethylene (PTFE), polyether ether ketone (PEEK) and silanized diatomaceous earth (DE).

What is Super-hydrophobic Cement? Applications and Advantages

What is Super-hydrophobic Cement? Super-hydrophobic cement, which is also known as luminescent cement, is produced by modifying the structure of cement. It absorbs and reflects lights which makes it an environmentally friendly material and an alternative to street lighting. Super-hydrophobic cement could be an astonishing solution to light up roads and buildings without any electrical […]
