Carbon nanotube/polysulfone soft composites: preparation, characterization and application for electrochemical sensing of biomarkers.
Multi-walled carbon nanotube/polysulfone soft composites (MWCNT/PSf) prepared via phase inversion are a novel platform for electrochemical and electroanalytical purposes with practical applications in the design of screen-printed electrodes for electrochemical sensing. We present here a thorough characterization of the morphological, physical, chemical and electrochemical properties of this material. These composites constitute a robust mesoporous network with high specific surface area, which is beneficial for trapping bioanalytes and increasing the electrochemical sensitivity. We highlight the advantages of these soft composites by comparing them with analogous graphite composites.
