  Abstract

In this study, the chemical changes in the fiber surface according to the acid treatment time of the metal fiber were analyzed by energy dispersive X-ray spectroscopy (EDS) analysis and contact angle analysis. Morphological changes were observed using scanning electron microscopy (SEM) with acid treatment time. We observed the wettability and surface energy by measuring the contact angle to investigate the effect of the surface properties of the metal fibers on the interfacial adhesion with the polymer resin. In addition, we prepared single fiber composite material specimens and measured the interfacial shear strength to investigate the potential of composite materials for wearable device applications. Consequently, the contact surface with the resin was increased owing to the increase in surface cracks and etching through the surface modification of the metal fiber, and the interfacial shear strength with the polymer was improved by making the surface hydrophilic according to the hydrophilic groups.
