Robust 2D layered MXene matrix-boron carbide hybrid films for neutron radiation shielding

Large-scale fabrication of neutron-shielding films with flexible or complex shapes is challenging. This paper demonstrates that a two-dimensional (2D) Ti₃C₂Tx MXene hybrid film with homogeneously distributed B₄C particles exhibits high mechanical flexibility and superior neutron-shielding properties. Layered and solution-processable 2D Ti₃C₂Tx MXene flakes serve as a robust and flexible matrix for high-content B₄C fillers (60 wt.%). A scalable neutron shielding MXene/B₄C hybrid paint is also presented, enabling integration with various large-scale surfaces. The films show a 39.8% neutron absorption capacity, making them promising for wearable and lightweight applications.
