A multifunctional composite composed of a spacer fabric and a porous graphene-based aerogel is proposed for sensing and impact protection applications. The material has good strain sensitivity, temperature sensitivity, and protection performance, as well as being lightweight, hydrophobic, and thermally insulating.
A multifunctional composite composed of a spacer fabric and a porous graphene-based aerogel is proposed for sensing and impact protection applications. The combination of the mechanical properties of the spacer fabric and the electrical properties of the graphene-based aerogel provides a versatile composite material with a strain sensitivity of 1.48, a temperature sensitivity of -0.004 degrees C-1, and a protection factor of 45%. The material is also lightweight, hydrophobic, and thermally insulating. It is therefore suitable for both high-temperature (nearly 180 degrees C) and low-temperature applications. Consequently, the developed multifunctional composite has potential for use as a building material and as a smart cushion for healthcare.
