Pickering emulsions as an alternative to traditional polymers: trends and applications

Abstract

Pickering emulsions have gained increasing interest because of their unique features, including easy preparation and stability. In contrast to classical emulsions, in Pickering emulsions, the stabilisers are solid micro/nanoparticles that accumulate on the surfaces of liquid phases. In addition to their stability, Pickering emulsions are less toxic and responsive to external stimuli, which make them versatile material that can be flexibly designed for specific applications, e.g., catalysis, pharmaceuticals and new materials. The potential toxicity and adverse impact on the environment of classic emulsions is related to the extractable nature of the water emulsifier. The impacts of some emulsifiers are related to not only their chemical natures but also their stabilities; after base or acid hydrolysis, some emulsifiers can be turned into sulphates and fatty alcohols, which are dangerous to aquatic life. In this paper, recent research on Pickering emulsion preparations is reviewed, with a focus on styrene as one of the main emulsion components. Moreover, the effects of the particle type and morphology and the critical parameters of the emulsion production process on emulsion properties and applications are discussed. Furthermore, the current and prospective applications of Pickering emulsion, such as in lithium-ion batteries and new vaccines, are presented.
