We report measured and calculated oil-ionic liquid, water-ionic liquid and oil-water contact angles on silica surfaces which have been hydrophobised to different extents by silanisation. Based on the idea that the contact angle formed by a liquid-liquid interface with a particle adsorbed at that interface is a key determinant of the strength of particle adsorption and the tendency of the adsorbed particle film to curve, we correlate the contact angle data with the phase inversion points and stabilities of the corresponding particle-stabilised emulsions.
我们报告了在通过硅烷化进行了不同程度疏水化处理的二氧化硅表面上测量和计算得到的油-离子液体、水-离子液体以及油-水接触角。基于这样一种观点，即由液体-液体界面与吸附在该界面处的颗粒形成的接触角是颗粒吸附强度以及吸附颗粒膜弯曲趋势的关键决定因素，我们将接触角数据与相应颗粒稳定乳液的相转变点和稳定性相关联。
