무전해 니켈 도금법을 이용한 고성능 도전사의 제조

Abstract

Highly conductive yarn was successfully obtained using electroless nickel plating method with palladium activation. In the presence of palladium seed on surface of fibers as a catalyst, continuos nickel layer produced on surface of fibers by reducing <TEX>$Ni${2+}$</TEX> ion in the electroless plating bath to <TEX>$Ni^0$</TEX>. It was found that the Pd-activation using <TEX>$SnCl_2$</TEX> and <TEX>$PdCl_2$</TEX> to deposit palladium seeds on the surface of fibers plays a key role in the subsequent electroless plating of nickel. It also found that electroless nickel plating on the fibers can induce the nickel-plated <TEX>$ELEX^{(R)}$</TEX> fibers to improve the electrical conductivity of the fibers. The thickness of nickel coating layer on the Pd-activated <TEX>$ELEX^{(R)}$</TEX> fibers and specific conductivity of the fiber were increased through electroless plating time. The temperature of nickel plating bath was very effective to enhance the nickel deposition rate.
