In recent years, the discovery and optimization of two-dimensional (2D) materials for environmental applications have garnered significant attention, particularly in treatment per- polyfluoroalkyl substances (PFAS). PFAS, known their strong carbon–fluorine bonds persistence environment, present a critical challenge due to resistance degradation harmful health effects. Traditional methods PFAS remediation are often resource-intensive inefficient. this study, we propose leveraging physics-based machine learning (PBM) models accelerate 2D treatment, through adsorption electrochemical degradation. The integration fundamental physical laws with an inverse PBM (IPBM) framework enables faster, more cost-effective predictions material properties tailored remediation. We highlight advancements materials, such as graphene, MXenes, boron nitride, potential This approach promises provide scalable, high-performance solutions address global contamination crisis, offering path forward developing advanced sustainable water technologies.

Per- or polyfluoroalkyl substances (PFASs) are man-made compounds involved in compositions of many industrial processes and consumer products. They categorized into two main families based on their molar mass: though low mass products (<1000 Da) toxic, mobile, bioaccumulable, cross the human membranes, others much higher masses, e.g., fluorinated macromolecules especially fluoropolymers, safe reliable, do not face such concerns, membranes (hence, they regarded as Polymers Low Concern), applications including medical high-value-added materials devices. Because former family has led to a severe global contamination, recent regulating agencies Europe (REACH) USA (EPA) have aimed at restricting fluorochemicals. Recently, consultations from affected organisms industries more than 5600 answers comments. This review supplies an update overall situation PFASs, limitations, regulations, end life, degradations, possible alternatives.
