1. 1. Exploring functionalization of colloidal silica for nanoparticle-stabilized emulsions

   Författare :Sanna Björkegren; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; thermo-responsive emulsions; functionalized colloidal silica; Pickering emulsions; NMR spectroscopy; surface activity; clouding;

   Sammanfattning : The main objective of this thesis was to evaluate how surface functionalized colloidal silica can be utilized in emulsions stabilized solely by particles, so called Pickering emulsions. To achieve this, water-dispersed silica nanoparticles were functionalized with hydrophilic and hydrophobic groups. LÄS MER
