摘要：

Exfoliated graphite (G) nanoplatelet was modified with hyxadecyltrimethylammonium bromide (C(16)TAB) and was constructed as multilayer films by electrostatic self-assembly. A [poly(sodium styrenesulfonate)/graphite](n) (PSS/G)(n) multilayer film was self-assembled by alternate adsorption of polynionic PSS and cationic graphite nanoplatelets G. An uniform deposition process was detected by UV-vis absorption spectra. The (PSS/G)(n) multilayer film exhibits an excellent electrical conductivity in the range of 50-200 S cm(-1), when bilayer number (n) exceeds a threshold value four, the conductivity of the multilayer film increases dramatically. Cyclic voltammogram measurement reveals that the (PSS/G)(n) film with more bilayer has small charge-transfer resistance and high electrocatalytic activity. (c) 2008 Elsevier Ltd.
