摘要：

Accurate modeling of contact electrification (CE) in insulating materials are essential for predicting and controlling their behavior. Here we propose a mesoscopic model based on the donor-acceptor mechanism, incorporating findings on surface patch features of identical dielectric materials from CE experiments. This model enables us to reproduce the charge transfer process and develop a macroscopic model that statistically captures this process. We implemented the macroscopic model in the discrete element code
