Constructing a Local Hydrophobic Cage in Dye

Herein a local hydrophobic cage is built up inside near-infrared (NIR) cyanine-anchored fluorescent silica nanoparticles (FSNPs) in which a hydrophobic silane coupling agent (n-octyltriethoxysilane OTES) is doped into FSNPs for the first time to significantly inhibit the ACQ effect and inward diffusion of water molecules Therefore the obtained optimal FSNP-C with OTES-modification can

Characterization of Transparent Hydrophobic Coating with

Schematic formulation of hydrophobic coating using (a) silica and (b) GO by sol-gel method The fabrication of the hydrophobic surface was achieved by spray deposition using spray-coater (JSpray 125-A) with a fluid nozzle having a diameter of 0 3 mm The glass substrate was heated at 60 oC prior to being used The distance between glass substrates and spray coater were made constant at 25 cm

Spreading of hydrophobic silica beads at water

The less hydrophobic silica beads (sample B) were postulated to be separated from each other by a layer of water molecules in the structured monoparticle layer This postulate has been supported by calculating the total interparticle interaction energies by applying the DLVO theory Introduction of 1 0 M NaCl did not appreciably affect the behavior of structured monoparticle layers prepared
