Abstract

The preparation of room-temperature electrical fasteners with high adhesion strength presents a major challenge at the micro- or nanoscale. A carbon nanotube (CNT)-Cu/parylene core/shell nanowire (NW) array room-temperature electrical fastener was therefore prepared, and is described herein. The shear adhesion strength of the CNT-Cu/parylene NWarray electrical fastener reached a maximum of 50.72N/cm2, which is six times higher than that of a metallic NW electrical fastener. A theoretical analysis indicated that the adhesion force of such a fastener can potentially be further improved by increasing the effective contact length between the CNTs and the Cu/parylene NW. The resistance of the fastener is 45.4Ω, which indicates that it has good electrical conductivity.
