Radiation synthesis of rapidly self-healing, durable, and flexible poly(ionic liquid)/MXene gels with anti-freezing property for multi-functional strain sensors

•The Poly(ionic liquids)/MXene organogels are firstly fabricated via radiation method.•The fabrication strategy is radiation-induced in situ polymerization and crosslinking.•The PILs/MXene gels possess a double cross-linked structure.•The gels exhibited rapidly self-healing ability, excellent anti-freezing properties.•The well-designed gels showing considerable potential in flexible wearable devices.
