Based on the Pickering emulsion template method, two types of Janus particles with different relative amphiphilic areas for stabilizing non-aqueous foam were synthesized. In addition, particles with uniformly modified surface were synthesized for comparison. By adjusting oil mixtures, the behavior of particles on the oil-air surface was measured. Moreover, the role of particle agglomerates in surface adsorption process was investigated. Affected by the particle surface contact angle, the surface activity of Janus particles is not always greater than that of uniformly modified particles, which is reflected on delta surface tension and the volume of foam generated. The oil-surface adsorption process of synthesized Janus particles is not only occurred in the form of independent detached particles, but also in the form of particle agglomerates. The adsorption of the particles from the bulk phase to the surface requires the contact angle of the Cassie–Baxter composite surface of the particle agglomerates to be around 90°, but the inherent contact angle of the individual particles is <90°.

基于Pickering乳液模板法，合成了两种具有不同相对两亲性面积的Janus颗粒，用于稳定非水泡沫。另外，合成了具有均匀改性的表面的颗粒用于比较。通过调节油混合物，测量了油气表面上颗粒的行为。此外，还研究了颗粒团聚体在表面吸附过程中的作用。受颗粒表面接触角影响，Janus颗粒的表面活性并不总是大于均匀改性颗粒的表面活性，这反映在δ表面张力和产生的泡沫量上。合成的Janus颗粒的油表面吸附过程不仅以独立的分离颗粒形式发生，而且以颗粒附聚物的形式发生。
