The facile and efficient encapsulation of a lubricant oil in SiO₂ wrapped polystyrene microcapsules is accomplished using a Pickering polymerization technique. Triton X-100-IPTS fumed SiO₂ nanoparticles are used as emulsifiers for the formation of O/W Pickering emulsions and the stability factor of the Pickering emulsions was investigated. The as-obtained microcapsules are characterized by scanning electron microscope, thermogravimetric analysis, Fourier transform infrared spectra and dynamic laser scattering. These results suggest that the microcapsules display a spherical shape with a core content of ∼38.3%, an average diameter of 3.3 μm, a shell thickness is ∼900 nm and outstanding thermal stability for lubricant oil with a decomposition temperature of 250 °C. Moreover, the microcapsules are embedded into an epoxy resin for self-lubricating coatings. On the basis of frictional coefficient measurements and wear testing, the self-lubricating microcapsules-incorporated epoxy coatings on an aluminum plate indicate the excellent dispersibility of the microcapsules in coatings and the favorable antifriction effects.

使用Pickering聚合技术可轻松有效地将润滑油包裹在SiO ₂包裹的聚苯乙烯微胶囊中。海卫一X-100-IPTS气相SiO ₂将纳米颗粒用作乳化剂以形成O / W Pickering乳液，并研究了Pickering乳液的稳定性因子。通过扫描电子显微镜，热重分析，傅立叶变换红外光谱和动态激光散射对所获得的微胶囊进行表征。这些结果表明，微囊呈球形，芯含量为〜38.3％，平均直径为3.3μm，壳厚度为〜900nm，并且对于分解温度为250℃的润滑油具有优异的热稳定性。此外，将微囊包埋在环氧树脂中以自润滑涂层。在摩擦系数测量和磨损测试的基础上，
