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

ABSTRACT: Large-scale fabrication of neutron-shielding films with flexible or complex shapes is challenging. Uniform and high boron carbide (B₄C) filler loads with sufficient workability are needed to achieve good neutron-absorption capacity. Here, we show that a two-dimensional (2D) Ti₃C₂T_x MXene hybrid film with homogeneously distributed B₄C particles exhibits high mechanical flexibility and anomalous neutron-shielding properties. Layered and solution-processable 2D Ti₃C₂T_x MXene flakes serve as an ideal robust and flexible matrix for high-content B₄C fillers (60 wt.%). In addition, the preparation of a scalable neutron shielding MXene/B₄C hybrid paint is demonstrated. This composite can b
