The droplet electrowetting dynamic behaviors on slippery lubricant-infused porous surfaces (SLIPS) remain elusive because the soft liquid-liquid interface nature is much different from solid dielectric hydrophobic surfaces. To understand the dynamic process, the impact of the voltage applied, the oil thickness, and viscosity on dynamic electrowetting behavior was experimentally studied, respectively. Meanwhile, a numerical dynamic model was also developed for the quantitative interpretation of the droplet dynamic spreading process on SLIPS. It is found the droplet always spreads smoothly to the equilibrium state without overshooting on the SLIPS. The droplet is always over-damped with the increase of applied voltage, the settling time is proportional to the 0.9th power of the electrowetting number. Then, by changing the silicone oil viscosity, it is found the viscous dissipation of the oil-water interface becomes dominant, causing the droplet to spread slowly. By fitting the theoretical models to experimental results, it is found the friction coefficient is nearly proportional to 1/6th power of oil viscosity and rarely influenced by applied voltage and oil thickness. Finally, it is found both the initial oil thickness and the high wetting ridge have a minor influence on the electrowetting dynamic spreading. The relationship between the actual oil layer thickness and the initial oil layer thickness was estimated. This study will provide helpful information and theory support for electrowetting-on-dielectric device design, lab on a chip, and other potential applications on SLIPS.

光滑的注入润滑剂的多孔表面（SLIPS）上的液滴电润湿动态行为仍然难以捉摸，因为软液-液界面性质与固体介电疏水表面有很大不同。为了了解动态过程，分别通过实验研究了施加电压、油厚度和粘度对动态电润湿行为的影响。同时，还建立了数值动力学模型，用于定量解释 SLIPS 上液滴动态扩散过程。发现液滴总是平稳地扩散到平衡状态，而不会在 SLIPS 上过冲。随着施加电压的增加，液滴总是过阻尼，稳定时间与电润湿数的 0.9 次方成正比。然后，通过改变硅油的粘度，发现油水界面的粘性耗散占主导地位，导致液滴扩散缓慢。通过将理论模型与实验结果进行拟合，发现摩擦系数几乎与油粘度的 1/6 次方成正比，几乎不受外加电压和油厚的影响。最后，发现初始油厚度和高润湿脊对电润湿动态扩展的影响较小。估算了实际油层厚度与初始油层厚度之间的关系。本研究将为介电润湿器件设计、芯片实验室和其他 SLIPS 潜在应用提供有用的信息和理论支持。导致液滴缓慢扩散。通过将理论模型与实验结果进行拟合，发现摩擦系数几乎与油粘度的 1/6 次方成正比，几乎不受外加电压和油厚的影响。最后，发现初始油厚度和高润湿脊对电润湿动态扩展的影响较小。估算了实际油层厚度与初始油层厚度之间的关系。本研究将为介电润湿器件设计、芯片实验室和其他 SLIPS 潜在应用提供有用的信息和理论支持。导致液滴缓慢扩散。通过将理论模型与实验结果进行拟合，发现摩擦系数几乎与油粘度的 1/6 次方成正比，几乎不受外加电压和油厚的影响。最后，发现初始油厚度和高润湿脊对电润湿动态扩展的影响较小。估算了实际油层厚度与初始油层厚度之间的关系。本研究将为介电润湿器件设计、芯片实验室和其他 SLIPS 潜在应用提供有用的信息和理论支持。发现摩擦系数几乎与油粘度的 1/6 次方成正比，几乎不受施加电压和油厚度的影响。最后，发现初始油厚度和高润湿脊对电润湿动态扩展的影响较小。估算了实际油层厚度与初始油层厚度之间的关系。本研究将为介电润湿器件设计、芯片实验室和其他 SLIPS 潜在应用提供有用的信息和理论支持。发现摩擦系数几乎与油粘度的 1/6 次方成正比，几乎不受施加电压和油厚度的影响。最后，发现初始油厚度和高润湿脊对电润湿动态扩展的影响较小。估算了实际油层厚度与初始油层厚度之间的关系。本研究将为介电润湿器件设计、芯片实验室和其他 SLIPS 潜在应用提供有用的信息和理论支持。
