Localized Quantitative Characterization of Chemical Functionalization Effects on Adhesion Properties of SWNT
Chemical modification of single-walled carbon nanotubes (SWNT) has been found to be an excellent method to promote SWNT dispersion, and possibly to improve interaction with matrices via covalent bonding. It is thus a quite promising technique to enhance the mechanical properties of SWNT-reinforced n...

Chemical modification of single-walled carbon nanotubes (SWNT) has been found to be an excellent method to promote SWNT dispersion, and possibly to improve interaction with matrices via covalent bonding. It is thus a quite promising technique to enhance the mechanical properties of SWNT-reinforced nanocomposites. However, the underlying mechanism of SWNT chemical functionalization effects on interfacial strength is not quantitatively understood, limiting their usefulness in the design of nanocomposites. In this work, an atomic force microscopy (AFM-) based adhesive force mapping technique combined with a statistical analysis method were developed and implemented to study adhesive interactions of small SWNT bundles functionalized by amino, epoxide, and hydroperoxide groups as compared to SDS-treated SWNT in controlled environment. Finally, the importance of such localized quantitative measurements in SWNT-reinforced nanocomposites design and fabrication was also discussed. |
