Superhydrophobic materials are found in a suite of scientific and industrial applications, given their broad potential use, there is great interest facilitating mass production. Although numerous methods have been used to produce superhydrophobic materials, only few capable fabricating surfaces at an scale. Techniques such as injection molding, compression hot embossing, polymer casting play important role the production surfaces. This technical literature review summarizes recent advances...
ABSTRACT Epoxy composites were prepared with different contents of hydrophobic silica aerogel particles to investigate their mechanical, thermal, and properties. The composites, particularly the one containing 1 wt % aerogel, showed remarkable toughness yielding behaviors compared neat epoxy, its brittle behavior. As content increased, thermal properties (e.g., conductivity stability) improved. This was due very low high stability particles. Moreover, use led development To examine...
Resorcinol–formaldehyde (RF) aerogels modified with amine groups were used to remove heavy metal ions from aqueous solutions. RF aerogel was synthetized under subcritical conditions and then by 3-aminopropyl trimethoxysilane. The ability of Pb(II), Hg(II), Cd(II) solution investigated using batch-adsorption technique respect the changes in pH, contact time, sorbent concentration, initial temperature. maximum adsorption capacity Cd(II), found happen at pH 6, 5, respectively, after about one...
Given the role of micro-nanostructures in producing superhydrophobic and icephobic surfaces importance high-quality replication these direct processes, we evaluated effect processing parameters on superhydrophobicity, icephobicity, quality silicone rubber created via micro-compression molding. Molding pressure, mold temperature, curing time, part thickness were selected as to be assessed. We used a response surface methodology illustrate optimal values parameters. pressure main influencing...
Icephobic surfaces offer an effective solution to protect the infrastructures subjected harsh cold-weather environment and increase their efficiency. Inspired by Nepenthes pitcher plant, liquid-infused coatings have received much interest as a potential cost-effective anti-icing solution. In this paper, we developed textured ( LITS ) through chemical etching followed replication method. We assessed effect of viscosity (50 500 cSt) infusion percentages lubricant on morphology icephobicity...
A facile method is introduced for production of micro-nanostructured silicone rubber surfaces by means direct replication using a compression molding system. The fabricated samples possessing surface roughness display water contact angle more than 160o and hysteresis (CAH) sliding less 5o. Such low wettability specimens verifies the induced superhydrophobic property. Chemically etched aluminum could work excellently as templates whose patterns were replicated on successfully. Various etching...
To address the increase in demand for superhydrophobic and icephobic surfaces with greater mechanical robustness, we fabricated damage-tolerant, abrasion-insensitive, bulk nanocomposites using a facile, cost-effective, industrially applicable, environmentally benign strategy. We prepared composed of high-temperature vulcanized silicone rubber through highly controlled incorporation nanosized fumed silica microsized aluminum trihydrate particles. The produced did not require additional...
In order to overcome the issues corresponding ice and pollution accumulation on silicone rubber high-voltage insulators, superhydrophobic self-cleaning surfaces were fabricated studied. Micro-nanostructures with water-repelling properties can be surface by direct replication using non-expensive bench top auto press. A facile chemical method was used create micro-nanostructures intended template. SEM images verify presence of replica. Using profilometry analysis quality assessed. The...
