Highly stable oil in water Pickering emulsions was formed at a low content of CNC−C18 (b). By tuning the pH of Pickering emulsions, 18-carbon alkyl chains were cleaved from CNCs and the emulsion was broken (a). Upon the replacement of n-hexane with a styrene/divinylbenzene mixed oil, cross-linked PS microspheres with amino-rich surfaces were created by the Pickering emulsion directed-radical copolymerization reaction, followed by acid treatment (c).
