Abstract:
In order to obtain washable high-conductivity textile materials, graphene oxide (GO) was used for the electrical conductive finishing of silk fabric by in-situ reduction. The influence of concentration of GO, pH value of GO solution, dosage of reducing agents, ultrasonic time and concentration of sodium dodecyl benzene sulfonate on the conductivity of the silk fabric was discussed. The conductive durability of the reduced graphene oxide (rGO) conductive silk fabric was analyzed, and the morphology of the silk fabric was characterized by scanning electron microscope. The results show that under the condition of GO of 15 g/ L, pH value of 5, reductant of 5 g/ L, ultrasonic treatment time of 30 - 60 min, the surface electric resistance of silk subjected to in-situ reduction is reduced to 1. 372 kΩ/ cm, and the conductivity of rGO coated silk fabric is excellent. The surface of silk is covered by GO sheets completely, and the surface electric resistance of the silk fabric is slightly changed after 20 times of standard washing or mechanical rubbing.
Key words: graphene oxide, silk fabric, in-situ reduction, electric conductivity, smart textile
