▎ 摘　　要

NOVELTY - The method involves immersing the commercially available linen cloth in a 0.05-1 mg/ml graphene oxide solution to sonicate for 0.5-1 h, and to dry at 60-80 degrees C to obtain a graphene oxide/linen composite material. The graphene oxide/linen composite is subjected to carbonization treatment at 300-900 degrees C under an inert to reduce the atmosphere of nitrogen, argon, helium or hydrogen, and is controlled by a temperature program. The graphene/linen pyrolytic derivative composite is immersed in an equal volume in a silver nanowire solution with predetermined concentration. The silver nanowire/graphene/linen pyrolytic derivative composite material is encapsulated by an elastic polymer silicone rubber material Ecoflex to obtain a composite flexible stress sensor. USE - Method for preparing silver nanowire/graphene/fabric carbon composite flexible stress sensor used for detecting movement of human joints such as finger, wrist, elbow, knee, and ankles (all claimed). ADVANTAGE - The preparation method is simple and reliable, the principle is clear, the preparation cost is low, the environment is friendly, and good mechanical properties and electrical resistance strain properties can be achieved. The preparation method has good scientific research prospects, and broad application prospects. DESCRIPTION OF DRAWING(S) - The drawing shows a graphical representation illustrating the scanning electron micrograph of a plain weave fabric.
