通过测量原子量级光滑的两表面间的法向作用力来认识粘着行为发生的过程及机理,利用分辨率为0.02 mN的表面力仪法向力测量系统对存在液体介质的云母表面分离过程中的分离力进行动态测量。在一定范围内,当中间层液体量越大,分离力也越大,粘着现象也就越明显。当中间层为粘性液体如石蜡基中性油时,粘滞力对粘着特性的影响较大;当中间层为小粘度的液体如去离子水时,液体的表面能会对粘着特性有显著影响。 By measuring the normal force between two surfaces of the order of magnitude, we can know the process and mechanism of the sticking behavior. By using the surface force meter with the resolution of 0.02 mN, Separation force for dynamic measurement. Within a certain range, the larger the amount of liquid in the middle layer, the greater the separation force and the more obvious the sticking phenomenon. When the middle layer is a viscous liquid such as paraffin-based neutral oil, the viscous force has a greater influence on the adhesive properties; when the middle layer is a liquid with a low viscosity such as deionized water, the surface energy of the liquid can significantly affect the adhesive properties .
