摘要
综观国内外学者近年对固体颗粒稳定的Pickering乳液及其聚合的研究,相关理论有界面理论和接触角理论,对其影响因素的分析主要有固体颗粒浓度、水相pH值和水相电解质.研究者已经将SiO2,Laponite粘土,磁铁矿等一系列无机固体颗粒成功地应用于Pickering乳液中,并制备出一系列性能各异的材料,但研究工作仍存在一些不足,如忽略固体颗粒的电性质对Pickering乳液的影响,对Pickering乳液的片状胶体颗粒稳定剂的研究不系统等.制备受单体影响小、性能稳定的新型Pickering乳液聚合稳定剂,从而不断丰富Pickering乳液及其聚合技术将是未来研究的热点.
Recent advances in Pickering emulsion stabilized by solid particles and Pickering emulsion polymerization were reviewed. It pointed out that the main stability theories of Pickering emulsion were the interface theory and the contact angle theory. The influence factors of Pickering emulsion included solid particle concentration,pH value and the type of electrolyte,etc. SiO2,Laponite and magnetite had been commonly used as solid stabilizers in Pickering emulsion polymerization. The shortages on Pickering emulsion research were also pointed out,such as neglecting the influence of electrical properties of solid particles and deficient research on lamellar colloidal particles as Pickering emulsion stabilizer. Preparing the new Pickering emulsion less affected by monomer with stable properties,so as to enrich Pickering emulsion and its joint technology will be the research focus in the future.
