2025年巴黎高科 - CSC合作公派讀博項目 - 課題No.55 2025 巴黎高科 - CSC公派博士項目 （12月8日截止） 網(wǎng)申通道：https://paristech.kosmopolead.com/phd 申請攻略：https://paristech.fr/fr/paristech-csc-phd-program-how-apply 課題55詳情: TITLE: WATCHING INTERFACIAL CHARGE DYNAMICS FOLLOWING LIQUID AND SOLID TRIBOELECTRIFICATION Topic number : 2024_055 Field : Energy, Processes Subfield: ParisTech School: ESPCI Paris - PSL Research team : Research team website: https://blog.espci.fr/jcomtet/ Research lab: SIMM - Sciences et ingénierie de la matière molle Lab location: Paris Lab website: https://www.simm.espci.fr/-Home-.html Contact point for this topic: jean.comtet@espci.fr Advisor 1: Jean Comtet - jean.comtet@espci.fr Advisor 2: Advisor 3: Advisor 4: Short description of possible research topics for a PhD: The universally-known triboelectric effect results in the charging of solid surfaces following mechanical contact. This ubiquitous phenomenon has macroscopic consequences, both mundane and fundamental (tribocharging leads to dust aggregation, which might be responsible for initial planetary formation [1]). Very recently, triboelectricity has also seen a surge of interest in the context of the development of novel energy harvesting devices with exceptional performances [2]. However, the origin of this surface charging remains fundamentally misunderstood, being indistinctively attributed to the transfer of minute quantities of electrons, ions or matter between surfaces [3]. We demonstrated recently the possibility to map the spatial distribution and temporal evolution of surface charges deposited during liquid triboelectrification, for which charge separation occurs due to the sliding motion of droplets on hydrophobic surfaces. Such spatio-temporal mapping allowed us to evidence the occurrence of spatially heterogenous charging patterns as well as a peculiarly high mobility of surface trapped charges, giving novel insights on their physicochemical nature. The aim of this PhD is to clarify the role of ion/surface interaction during liquid tribocharging and extend these approaches to the case of solid triboelectrification between insulating dielectric materials, whereby charge separation occurs during frictional sliding. By coupling well-controlled tribological solicitations with spatially and temporally resolved mapping of deposited surface charges, we will attempt to relate the local frictional solicitations to the surface electrification processes, hoping to obtain novel insight on these fundamentally misunderstood electrification processes, with both fundamental and practical implications.
