Graphene Oxide/ Gold Nanoparticles Thin Layers As Adhesion Promoters For Copper Deposition On Glass
Résumé
Thin and ultrathin metal coatings are increasingly required by the electronics and optics industries on
all types of substrates. However, the adhesion of noble metals is very poor on non-metallic substrates like glass,
other oxide materials and polymers. By contrast, CVD graphene has a strong adhesion energy (~0.31-0.45 J.m-2
depending on the number of layers) on glass [1]. On the other hand, graphene oxide (GO) was recently shown to
promote adhesion of ZnO nanoparticles and subsequent ZnO films on glass or silicon substrates [2].
In this work we use GO/Au nanoparticles (NP) composite thin films as bifunctional materials to both
promote adhesion on glass and assist the deposition of copper in electroless wet industrial coating processes. We
discuss the influence of the NP density, surface treatment and deposition parameters on the homogeneity and
adhesion of the GO/Au NP and copper layers.
