摘要：

An intelligent material with shear thickening, flame-retardant and sensing properties was prepared by intro-ducing mesoporous silica and carbon nanotubes to ionic liquids. By impregnating the conductive shear thick-ening fluid (STF) on Kevlar fabric and drying in an oven, CNTs/STF/Kevlar composite was obtained. Due to the rate-sensitive performance of STF, the yarn pull-out force of CNTs/STF/Kevlar increased 3-4 times compared with that of neat Kevlar, once the impregnation weight gain is 55 wt%. Furthermore, the CNTs/STF/Kevlar composite can maintain intact at 110 m/s incident velocity of bullet, whereas neat Kevlar fabric was penetrated at the same velocity, and exhibited the flame resistance as well due to the thermal insulation property of mes-oporous silica and flame-retardant performance of ionic liquids. Then, CNTs/STF/Kevlar composite also per-formed obvious sensing characteristic due to the introducing of carbon nanotubes, and showed the application potential in the field of safe wearable equipment.
