This work focuses on the dispersions of carbon nanotubes in surfactants and biopolymers water-based matrices. The main objective is to determine the critical parameters govering the dispersions in concentrated systems. The use of complex aqueous matrices is thought to be relevant in the future design of improved biomaterials. For these purposes, matrices with interesting orienting capabilites and/or mechanical properties are taken into account. Carbon nanotubes were dispersed in micellar and micellar nematic surfactant (sodium dodecyl-sulfate, triton-X-100) systems and concentrated biopolymer (DNA, lysozyme) solutions. The systems were characterized with rheology, microscopies, dynamic light scattering, electrophoretic mobilities measurements and NMR spectroscopy.
Questo lavoro riguarda dispersioni di nanotubi di carbonio in surfattanti e biopolimeri in soluzione acquosa. Il principale obiettivo è determinare i parametri critici che governano le dispersioni in sistemi concentrati. L'uso di matrici acquose complesse è pensato essere rilevante nella futura preparazione di biomateriali. Per questo scopi, matrici con interessanti capacità orientazionali e/o proprietà meccaniche notevoli sono considerate. I nanotubi di carbonio sono stati dispersi in sistemi micellari e nematici di sodio dodecil solfato e biopolimeri concentrati (DNA, Lisozima). I sistemi sono stati caratterizzati con reologia, microscopie, scattering dinamico della luce, mobilità elettroforetica e NMR.

Abstract
This work focuses on the dispersions of carbon nanotubes in surfactants and biopolymers water-based matrices. The main objective is to determine the critical parameters govering the dispersions in concentrated systems. The use of complex aqueous matrices is thought to be relevant in the future design of improved biomaterials. For these purposes, matrices with interesting orienting capabilites and/or mechanical properties are taken into account. Carbon nanotubes were dispersed in micellar and micellar nematic surfactant (sodium dodecyl-sulfate, triton-X-100) systems and concentrated biopolymer (DNA, lysozyme) solutions. The systems were characterized with rheology, microscopies, dynamic light scattering, electrophoretic mobilities measurements and NMR spectroscopy.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
