(a) (b) SEM images of the paper surface constructed by cellulose fibers and Kaolin. The Kaolin served as a sizing agent which hinders the penetration of binder. (c)~(f) Cross section at the interface between ECA (50 wt%) and substrates; From c to f, the substrates are PET, craft paper, printing paper and pulp paper; These figures clearly show that silver flakes are condensed with the decrease of sizing degree of the substrates.
