For the application development of interfacial nanobubbles (INBs), it is of great significance for understanding the special physicochemical characteristics of INBs and the interactions with hydrophilic and hydrophobic surfaces. In this paper, the morphology of INBs was scanned and the interaction between INBs and different surfaces were researched by atomic force microscope with the prepared hydrophilic/hydrophobic probes. In this investigation, the dynamics of INBs growth was obtained. The hydrophilic probe is essential to scan the complete morphology of INBs. Based on the detailed analysis of the interaction between the INB and the hydrophilic probe, the vertical height of the INB corresponding position can be calculated from the extending force curve. By setting different applied forces, it is found that there is a positive correlation between the INB vertical height and the applied force, that is, the higher position of INB needs the greater applied force to reach the bottom of the INB. For instance, the point a (7.4 nm) and the point d (65.4 nm) require 0.7 nN, 6.5 nN, respectively. The morphology of INBs is seriously deformed with the hydrophobic probe. What is more, there is only one inflection point on the extending force curve so that the vertical height of INBs cannot be calculated. In addition, the interaction between INBs and hydrophobic surface is significant stronger, comparing with hydrophilic surface.

对于界面纳米气泡（INBs）的应用开发，对于理解INBs的特殊理化特性以及与亲水性和疏水性表面的相互作用具有重要意义。本文用原子力显微镜和制备的亲水/疏水探针对INB的形貌进行了扫描，研究了INB与不同表面的相互作用。在这项调查中，获得了INBs生长的动力学。亲水探针对于扫描INB的完整形态至关重要。基于对INB和亲水性探针之间相互作用的详细分析，可以从延伸力曲线计算出INB对应位置的垂直高度。通过设置不同的作用力，发现在INB的垂直高度和作用力之间存在正相关关系，即，INB的位置越高，到达INB底部的作用力就越大。例如，点a（7.4 nm）和点d（65.4 nm）分别需要0.7 nN，6.5 nN。疏水探针使INB的形态严重变形。而且，在延伸力曲线上只有一个拐点，因此无法计算INB的垂直高度。此外，与亲水性表面相比，INB与疏水性表面之间的相互作用明显更强。分别为7 nN，6.5 nN。疏水探针使INB的形态严重变形。而且，在延伸力曲线上只有一个拐点，因此无法计算INB的垂直高度。此外，与亲水性表面相比，INB与疏水性表面之间的相互作用明显更强。分别为7 nN，6.5 nN。疏水探针使INB的形态严重变形。而且，在延伸力曲线上只有一个拐点，因此无法计算INB的垂直高度。此外，与亲水性表面相比，INB与疏水性表面之间的相互作用明显更强。
