Hydrophobic mesoporous silicon dioxide for improving foam
In this study, mesoporous SiO2 nanoparticles (MSNs) were synthesized via a sol–gel method and modified with (3-chloropropyl) trimethoxysilane to make them hydrophobic (MMSNs). The material was characterized via SEM, TEM, FT-IR, DLS, BET and contact angle measurements. The MMSNs have good foam stability, so that the
Hydrophobic Modification of a Mesoporous Silica Surface Using
Hexagonal mesoporous silica (HMS) material, which is commonly used in catalysis and the nanostructural design field as an adsorbent or host material, was hydrophobically modified via a simple silylation process using a fluorine-containing silylation agent, triethoxyfluorosilane [TEFS or SiF(OEt)3]. Structural analyses performed by XRD and N2 adsorption−desorption suggested that the

How to make SiO2 surface hydrophilic?
I have read from literature that bare silicon wafer "P-type, <100>" is hydrophobic in nature. But this state is not stable as it quickly oxidizes (native oxide). Then becomes hydrophilic (water
KR20120105872A - Manufacturing method for hydrophobic
PURPOSE: A method for manufacturing hydrophobic mesoporous silica, porous absorbent using the same, and a biogas refining system using the porous absorbent are provided to prevent the occurrence of mechanical malfunction by shortening or omitting an existing plurality of processes for refining biogas.
Mesoporous silica nanoparticles in medicine : recent advances
In most cases small hydrophobic drugs have been used, but recent in vitro studies demonstrate that MSNs are highly interesting for gene delivery applications. This review covers recent advances related to the therapeutic use of mesoporous silica nanoparticles (MSNs) administered intravenously, intraperitoneally or locally.
Hydrophobic Silica - AMS Applied Material Solutions
Improve the flow characteristics and charge stability and enhance the resolution and print quality of toners. Applications. Printing inks and toners; Reinforcement of Elastomers. Improve mechanical properties, such as tensile strength, elongation at break, and tear resistance, and help control the influence of temperature on mechanical properties.
The difference and application of hydrophilic silica
Some products, after structural modification on the basis of hydrophobic treatment, can provide further help for customers to develop new products and improve product performance. For example, in the liquid system, hydrophobic fumed silica can reach a high content, but has little effect on the viscosity of the system.
Mesoporous Silicates Prepared Using Preorganized Templates
Well-ordered mesoporous silicate films were prepared by infusion and selective condensation of silicon alkoxides within microphase-separated block copolymer templates dilated with supercritical carbon dioxide. Confinement of metal oxide deposition to specific subdomains of the preorganized template yields high-fidelity, three-dimensional replication of the copolymer morphology, enabling the
