摘要：

首先将聚烯丙基胺盐酸盐与碳纳米管制成复合物(PAH-CNT), 再通过层层组装技术构筑了聚丙烯酸和碳纳米管混合物(PAA-CNT)与PAH-CNT多层复合膜(PAH-CNT/PAA-CNT). PAH-CNT/PAA-CNT多层复合膜同时具有导电和黏附性能. 在玻璃和ITO基片上沉积的PAH-CNT/PAA-CNT多层复合膜的最大拉伸剪切强度接近7 MPa, 即1 cm2的黏附膜可以承受约70 kg的重物. 碳纳米管的引入使PAH-CNT/PAA-CNT多层复合膜具有更好的导电性.

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
