Study in the experimental manipulation of Janus particle synthesis via emulsion-based method

This study focused on the investigation in the influencing factors of the Granick?s method for Janus particle synthesis, in which selective modification of colloidosome made from a Pickering emulsion-based process was the essential strategy. Homogenizer with high shearing forces was introduced to make stable emulsion. With increased stirring speed of the homogenizer, the sizes of the colloidosomes decrease. And the stirring time of the homogenizer and the paraffin melting point have also been proved to have influence on the size distribution of colloidosomes as well as on the assembly morphology of the silica particles on the surface of the wax sphere. 160?s of the working time and the melting point of 53?57??C were tested respectively to be the optimal condition for making the ideal colloidosomes. By using the optimized experimental conditions, silica particles with diameters of 200, 400, and 600?nm all had success in making fine colloidosomes. The Janus character were characterized by demonstrating the abilities of interfacial assembly and anisotropic structural growth of the resultant products from the optimized procedure. The research provides the conclusions of optimal experimental conditions as references for achieving scalable synthesis of Janus particles with satisfactory quality. This research could serve as a guidance to effective implementation of Granick?s method of Janus particle synthesis.
