In this work, conductive polyamide fibres were successfully prepared through polymerization of thiophene on the surface of polyamide fibres based on fibre pretreatment and surface activation modification. Sulfuric acid was utilized to roughen the polyamide fibres to increase the activity. Tannic acid (TA) was oxidized and grafted onto the roughened polyamide fibres to convert the inert surface into a highly adhesive tannic acid surface, thus improving the fastness of polythiophene on fibre surface. The effects of treatment temperature, time and pH were investigated in the preparation process. The surface morphology and chemical structure of the conductive fibres were analyzed by scanning electron microscope (SEM), X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared spectrometer (FTIR). The prepared conductive polyamide fibres have robust electrical conductivity, good strength, thermal stability, resilience, washing fastness, sensing properties and electrothermal properties, providing potential applications in flexible electronic devices, functional sensors and infrared assisted therapy.
