Abstract

Abstract:

Water-based highly adhesive films with satisfactory electrical conductivity were constructed by Layer-by-Layer(LbL) assembly technique. Poly(allylamine hydrochloride) and carbon nanotube(CNT) complexes(PAH-CNT) were assembled with a blend of poly(acrylic acid) and CNT(PAA-CNT) to produce PAH-CNT/PAA-CNT films. Strong adhesion as high as 7 MPa can be achieved when glass substrates deposited with LbL assembled PAH-CNT/PAA-CNT films are slightly pressed together, which means that the glued conductive adhesive films with an area of 1 cm² can hold a weight of approximate 70 kg. The thin nature of the adhesive films and the incorporated carbon nanotubes endow the adhesive films with satisfactory electrical conductivity.

Key words: Layer-by-Layer assembly(LbL), Water-based adhesive, Electrically conductive adhesive film, Carbon nanotube
