| Description | The aim of the present work was the study of mechani- cal properties of MWCNT/PU. Four types of coatings were compared. Two different concentrations of MWCNTs com- mercially functionalized with COOH group were prepared and studied. These composites showed improved mechanical properties compared to PU, and the modified nanotubes proved to be much better fillers than the unmodified MWCNTs due to stronger filler-to-matrix attachment. Be- cause the modified nanotubes seem to be much more conven- ient composite filler, the first experiments with nanotube modification have been carried out. Modification using induc- tively coupled discharge in argon and oxygen mixture was successful and the mechanical properties of the composite were increased at the same level as in case of the commer- cially COOH functionalized MWCNT fillers. |
