Carbon‐Nanotube/Silver Networks in Nitrile Butadiene Rubber for Highly Conductive Flexible Adhesives

Abstract

An adhesive with high conductivity, flexibility, cyclability, oxidation resistance, and good adhesion is developed using microscale silver flakes, multiwalled carbon nanotubes decorated with nanoscale silver particles, and nitrile butadiene rubber. Light-emitting-diode chips are attached to the conductive, flexible adhesive pattern on a poly(ethylene terephthalate) substrate as a visual demonstration. The brightness is invariant during bending tests.

Fabrication of conductive elastic nanocomposites via framing intact interconnected graphene networks

“…Electrically conductive elastic nanocomposites with excellent abrasive resistance, high elasticity and good tightness have been widely used in various fields including sealing [1], electrostatic paints [2], electromagnetic shielding [3], stretchable electronics [4], flexible displays [5], smart skin [6], and implantable devices [7]. With low density, good chemical resistance, excellent electrical property, carbon-based fillers, such as carbon blacks [8], carbon fibers [9], carbon nanotubes (CNTs) [10] and graphene [11], have been introduced into elastomers (or rubbers) to take the advantages of the synergetic effect from the conductive carbon fillers and elastomers.…”

“…15 Ma et al reported highly conductive exible adhesives (CFAs) composed of nanoscale Ag akes, CNTs and nitrile butadiene rubber. 16 Pillai et al reported a conductive hybrid network consisted of silver nanowires (Ag NWs) and SWCNT, which has been demonstrated potential in high energy density exible-solid-state supercapacitor. 17 Dong et al fabricated the Ag/CNTs networks for a highly conductive lm.…”

A highly stretchable, helical copper nanowire conductor exhibiting a stretchability of 700%

“…[6][7][8][9] The first strategy is the inclusion of micro-or nano-scale conductive carbon materials into elastic polymer matrices. 1,[10][11][12][13] For example, carbon-based materials, such as carbon nanotubes and graphene, have been extensively researched for stretchable/foldable conductors. Ma et al 13 fabricated helical ribbon-structured composites composed of carbon nanotubes and Ag flakes using a shape-memory polymer, demonstrating stable resistivity up to a strain of 600%.…”

Ma et al 13 fabricated helical ribbon-structured composites composed of carbon nanotubes and Ag flakes using a shape-memory polymer, demonstrating stable resistivity up to a strain of 600%. However, the application of these materials in large-area, integrated devices may be restricted by their relatively poor electrical properties and their high cost.…”
