Application of scanning force microscopy in nanotube science

Abstract: Recent developments in the application of scanning force microscopy in nanotube science are reviewed. The non-destructive character of this technique allows the structural characterisation of (chemically modified) single-and multi-wall nanotubes deposited on substrates for further investigations such as electrical transport measurements. Furthermore, SFM is now an established tool for manipulation of nanotubes, which allows position control and determination of elastic constants such as the Young's modulus. Fi… Show more

“…This result confirms experimental observations ,,,, that carboxylation at some point leads to the deterioration of CNTs. Moreover, if the concentration of highly carboxylated CNTs in a composite matrix is sufficient, they will form large agglomerates, , thus making strong carboxylation useless for solving the bundling problem of pure CNTs. It should be emphasized that the results presented in this work perfectly describe those trends.…”

“…Nearly all theoretical studies of carboxylated CNTs , present a picture that is not consistent with experimental observations. ,, Many people have falsely believed that the common oxidizing acid functionalization treatment yields CNTs with COOH groups added to the sidewall and that the carboxylation and grafting processes lead to similar property changes. Nevertheless, carboxylation is usually carried out by treating CNTs with oxidizing inorganic acids, such as HNO 3 and H 2 SO 4 , alone or in combination with peroxide. ,,, ,, The carbon atom in the COOH linkage is one of the CNT backbone carbons. This requires one of the sidewall carbon atoms to have three new bonds to oxygen atoms, leaving only one bond to another sidewall carbon, which means that a surface group and a vacancy in the CNT wall are present simultaneously.…”
