Localized Quantitative Characterization of Chemical Functionalization Effects on Adhesion Properties of SWNT

Table 2

Adhesion forces normalized on mica. CNT with amino function group and SDS-wrapped CNT have larger adhesion force than the other two.

Functional groups	Adhesion on nanotube (Unit: nN)	Adhesion on mica (Unit: nN)	Normalized adhesion on nanotubes
Amino	8.71±1.05	12.35±0.65	0.70
Epoxide	4.20±1.25	8.22±0.38	0.51
Hydroperoxide	7.77±1.28	15.61±0.88	0.50
SDS	5.00±0.70	6.98±0.57	0.72
