LanguageEnglish Pages1800328 AC measurements were carried out with a LUMiSizer LS 651HSPHDPTo obtain quantitative understanding of the effects of a chemisorbed organic modification on the surface of particles 5 more the use of Reichardt’s dye (RD) and Hansen solubility parameter (HSP) is discussedwhereby the S should be understood in terms of “similarity” rather than solubility as dispersibility is in focus. Silica nanoparticles modified to different extents with a medium chain silane including completely hydrophilic and hydrophobic particles are chosen. During spray-drying such particles form fully redispersible micro-raspberryNanostructured micro-raspberry powders (0.5 wt%) of SiO2-NPs superstructures. After qualitative estimations of the particles’ polarity based on measuring both immersion time and ability of modified particles to stabilize oil–water emulsionssurface properties are quantified by HSP and RDanalytical centrifugation More details Edition2018 Internal reference1775 Open publication →
