“…Emulsification in the HPPF geometry is possible due to the forced passage of the droplet containing phase through the turbulence field after the orifice valve [83,84]. However, the droplets do not get elongated at the valve inlet, which is reported to be essential for the disruption of high-viscous droplets [47,85,86].…”

Composite nanostructured particles can be produced by polymerization of monomer miniemulsion droplets loaded with inorganic nanoparticles. The article gives an overview on the development of a scalable continuous process for the production of such hybrid nanoparticles via miniemulsion polymerization. Different possibilities for the necessary surface modification of the inorganic material are discussed in detail. Furthermore, the influence of the surfactant concentration on the droplet size after emulsification as well as on the nucleation mechanisms during polymerization is highlighted. Possible process routes for the emulsification of the nanoparticle-loaded monomer phase are compared taking into account different process and material parameters, such as energy consumption, abrasion, dispersed phase viscosity, inorganic particle load and size, and morphology of the resulting hybrid particles. The possibility of an industrial implementation via an integrated high pressure homogenization process and a subsequent continuous polymerization are presented.

Conventional high-pressure homogenization (HPH) is widely used in the pharmaceutical, chemical, and food industries among others. In general, its aim is to produce micron or sub-micron scale emulsions with excellent product characteristics. However, its energy consumption is still very high. Additionally, several limitations and boundaries impede the usage of high-pressure homogenization for special products such as particle loaded or highly concentrated systems. This article gives an overview of approaches that have been used in order to improve the conventional high-pressure homogenization process. Emphasis is put on the 'Simultaneous Emulsification and Mixing' process that has been developed to broaden the application areas of high-pressure homogenization.
