Abstract

The assembly of nanoparticle building blocks and suitable binders provides a versatile approach for functionalising electrode surfaces with porous and/or functional structures. Examples of structures include TiO2-based films [1], Fe2O3-based films [2], composite TiO2-Au-based films [3], films incorporation SnO2 nanoparticles [4], carbon nanoparticles [5], and purely organic structures based on reconstituted cellulose-nanofibrils [6]. In this presentation electrical conductivity in these types of nano-composite films will be surveyed and compared. Novel mechanisms based on surface processes and based on “Faradaic coupling” will be discussed.
