MWCNT buckypaper disc films as alternative to the drop casting method to modify electrode surfaces

We report the comparison of the modification of glassy carbon electrode (GCE) with multiwalled carbon nanotubes (MWCNTs) and nitroaromatic compounds using two different methodologies, the traditional drop casting (DC) method and an alternative buckypaper disc film (BP) method. The methodology for the construction of the BP disc film electrodes consists of a simple filtration of MWCNT and polystyrene (PS) dispersion in 1,3-dioxolane through a nylon membrane filter and then disc-shaped cutting. The adhesion of the disc film to the GCE is achieved by a direct STAMP process.
