Dual-Elastomeric Coated Multifunctional Textile Armor with Cutting-Fire Protection and Strain Sensing

Smart textiles with anticutting, antiflame, and motion sensing capabilities are highly desirable in wearable electronics and personal protective equipment but remain a challenge. Here we report a dual-elastomeric coating strategy to construct multifunctional textile armor with cutting-fire resistance and strain sensing properties. The armor was coated by immersion photocuring of durable ionotronic and thermal stable elastomers. The resulting textile exhibits robust protective properties, including a 5-fold increase in cut-resistance and flame-retardancy with a thermal deposition temperature exceeding 450 °C. Its strain-sensing capability is retained after enduring 10 washes and 300 cycles even under 10% tensile strain. These features offer textile extreme protection and motion detection capabilities. This work provides a scalable and effective empowerment strategy for smart multifunctional textiles toward a healthy human life.
