中文摘要	poly(4-vinylpyridine) (p4vb) was grafted to multiwalled carbon nanotubes (mwcnts) by an in situ polymerization. this grafted polymer plays two roles in the synthesis of prussian blue (pb)/mwcnt composites: (1) a stabilizer to protect pb nanoparticles from aggregation: (2) a linker to anchor these nanoparticles on the surface of mwcnts. the size of pb nanoparticles deposited on mwcnts can be controlled by in site layer-by-layer coordination of fe3+ and fe(cn)(6)](4-) ions in aqueous solution. the as-prepared pb/p4vp-g-mwcnt composites were characterized by fourier transform infrared spectroscopy, transmission electron microscopy, x-ray photoelectron spectroscopy and x-ray powder diffraction, which revealed that these pb nanoparticles were uniformly distributed on the surface of mwcnts, and grew upon layer-by-layer assembly. a potential use of pb/p4vp-g-mwcnt composites was demonstrated as an electrocatalyst used in the electrochemical detection of l-cysteine. the as-prepared electrodes modified with pb/p4vp-g-mwcnt composites showed two reversible redox waves assigned to a fast surface-controlled processes. the analytical performance for l-cysteine detection is associated with the load of pb nanoparticles onto mwcnts. in an optimal experiment, for these as-prepared electrodes, their detection limit of l-cysteine can be measured as low as 0.01 mu m with a sensitivity 778.34 na mu m-1 cm(-2). crown copyright (c) 2012 published by elsevier b.v. all rights reserved.
