  Abstract

In this study, a conductive thermoplastic elastomer (TPE) filament coated was developed with a graphene/polyvinyl alcohol composite solution by spray-coating it with an airbrush. The graphene/polyvinyl alcohol composite solution was prepared with three types of graphene content of 2 wt%, 8 wt%, and 16 wt%, and coated it 1, 5, 10, 15, 20, and 25 times. The prepared samples were analyzed by means of morphology, increase of diameter, pick-up rate, differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), tensile strength, and conductivity. From the morphology and the increase of diameter and pick-up rate, it was confirmed that the diameter and weight increased as the graphene content and the number of coatings increased. In DSC, glass transition temperature and melting temperature were similar to those of TPE, but the enthalpy was increased as the number of coatings increased. For TGA, the residue increased as the graphene content and the number of coatings increased. For tensile strength, it was confirmed that the graphene content of 2 wt% composite solution had the best adhesion to the TPE filament surface resulting in a great tensile strength. The conductivity was the best when coated with a 16 wt% composite solution. Therefore, this study confirmed that the conductive filament, which is intended to be applied to wearable healthcare clothing in the future, needs to be coated with a 16 wt% graphene composite solution.
