“…Interfacial friction mainly involves two sides of applications: From the perspective of the bright side, interfacial friction can obtain interfacial mass and energy transfer for surface cleaning, energy harvesting, or liquid harvesting. From the other perspective of the dark side, friction causes energy loss, surface wearing, or surface corrosion [254]. Considering both sides of the interfacial friction in certain applications, we summarize the applications of interfacial friction from two classifications: friction-inhibited and friction-reinforced applications.…”

Friction is a fundamental force that impacts almost all interface-related applications. Over the past decade, there is a revival in our basic understanding and practical applications of the friction. In this review, we discuss the recent progress on solid-liquid interfacial friction from the perspective of interfaces. We first discuss the fundamentals and theoretical evolution of solid-liquid interfacial friction based on both bulk interactions and molecular interactions. Then, we summarize the interfacial friction regulation strategies manifested in both natural surfaces and artificial systems, focusing on how liquid, solid, gas, and hydrodynamic coupling actions mediate interfacial friction. Next, we discuss some practical applications that are inhibited or reinforced by interfacial friction. At last, we present the challenges to further understand and regulate interfacial friction.

“…Additionally, droplet-based electricity generators proposed by W. Xu et al and N. Zhang et al [31,32] prove an important contribution of the metal electrode in the charge-transfer process between the insulating layer and the electrode when water is in contact with both, resulting in enhancing output performance of their TENGs. Moreover, X.-H. Hou et al [33,34] demonstrated that a unidirectional current can be generated because of the friction when water/oil flows through a metal pipe. J. Y. Hwang et al [35] also reported a DC-powerharvesting system by using streaming electrification and an opposite charge extractor.…”

This study aimed to develop a simple but effective mechanical-to-electrical energy conversion for harvesting hydrokinetic energy based on triboelectric nanogenerator (TENG) technology. Here, a direct-current fluid-flow-based TENG is reported as a potential solution to solve the inconvenience of directly powering electronic devices where direct-current (DC) power is required. The falling of a water droplet (about 1.06 mL) from an elastomeric pipe can generate an open-circuit voltage of ~35 V, short-circuit current of 3.7 µA, and peak power of 57.6 µW by passing through a separated electrode. Notably, the electrical responses have the distinct characteristics of pulsed direct current. The ability to generate DC outputs enables the TENG to directly drive electronic devices. Our experimental results prove that this TENG can act as a power source to directly light up 50 light-emitting diodes without requiring a rectifier, and, also, the produced electric energy was demonstrated that can be stored directly in a capacitor to power commercial temperature and humidity IoT sensors. Furthermore, the device shows a greatly varied output voltage based on the droplet flow rate, with a linearity R2 = 0.998. This work highlights a promising potential for applications in harvesting hydrokinetic energy and self-powered sensors and systems.

“…Therefore, the generation and accumulation of the electrostatic charge should be focused and concerned. Not a few literatures have carried out a large number of researches and summarized a set of antistatic safety measures, which have achieved good results [6][7][8][9][10][11], but owing to the many factors and complicated mechanisms of the charge generation [12,13], the report about the influence of the flow rate on it is very little, it is necessary to expand and further study the flow electrification phenomenon.…”

The interfacial electrification properties play an important role in the electrochemical corrosion reaction which leads the electrostatic charge to generate and accumulate on the metal surface when the insulating oil flows through a metal pipe. In this paper, the interfacial electrification properties resulted by the oil flow rate and the action of electric charge trapper are investigated by measuring the current and potential on the surface of the test metal pipe. The measured results showed that the current and potential between the metal pipe and the earth increased with the rise of flow rate; and as the flow rate increased, the growth trends of the current and potential difference between two close flow rates increased and decreased, respectively, while there was an electric charge trapper set in the radial direction of the pipe, the measured current and potential decreased compared with that of without electric charge trapper, which was because it captured and caught part of charge in the oil flow bulk to neutralize the opposite charge on the surface of the metal pipe.
