Electrode comprising metal nano particles having conductive polymer shell and conductive film and preparation method thereof

Abstract

The invention discloses an electrode comprising metal nano particles having a conductive polymer shell and a conductive film and a preparation method thereof. Specifically, the invention discloses anelectrode for a fuel cell. The electrode comprises a polymer matrix; and a catalyst dispersed in the polymer matrix. The catalyst has a shell-core structure. The shell-core structure comprises a corecontaining metal nano particles and a shell containing a conductive polymer. According to various embodiments, conductive polymers other than (3-hexyl) thiophene (P3HT) and metal nano particles are combined to form various hybrid nano composite materials. For example, the preparation method comprises a step of selectively placing metal nano particles on a surface-modified conductive polymer, whichcomprises a segmented copolymer comprising two or more types of conductive polymers.
