Interface Mechanism and Electrical Conductivity Optimization of Graphene Textile Fiber Composite Materials

Against the backdrop of rapid development in emerging fields such as flexible electronics, smart wearables, and electromagnetic shielding, conductive textile materials that combine high conductivity, flexibility, breathability, and mechanical stability have become a research hotspot. Graphene, as a two-dimensional nano conductive material, has ultra-high conductivity, excellent mechanical properties, and chemical stability. It can be combined with textile fibers to prepare high-performance conductive composite materials. However, there are fundamental challenges such as poor interface compatibility, low bonding strength, and uneven dispersion between graphene and textile fibers, which lead to rapid degradation of the conductivity and insufficient mechanical stability of composite materials, severely restricting their large-scale application. The interface-regulated conductive network supports applications such as flexible electrodes, smart fabrics and electromagnetic shielding textiles.
