Single wall carbon nanotubes - polymer composite materials and their biomedical applications

This work aims at illustrating a new composite material (CM) useful in biomedical field. In particular, the composite obtained through the self-grafting of a Single Wall Carbon Nanotubes (SWCNT) aqueous dispersion onto the poly-dymethyl-siloxane (PDMS) film surfaces is investigated. Both electrical and mechanical properties of this CM have been analyzed, a new investigation has been carried out to confirm the stability of SWCNT grafting and the prototype of an artificial bladder has been realized. This study proves a good reliability of the CM due to about 100 μm of SWCNT penetration depth into the polymer surface and consequently its excellent electro-mechanical properties.
