Abstract The experimental studies of the adhesion of vertically aligned carbon nanotubes (VACNT) array were carried by atomic force microscopy (AFM) using two probes with radiuses of 35 and 220 nm. It was shown that the dimension of the local adhesion (VACNT) array calculated according to the survey probe with a radius of 35 nm is significantly exceeds the theoretical one because of the small contact area of the array surface with the AFM probe. Using the probe with a 220 nm radius allowed us to estimate the macro adhesion of the VACNT array which amounted 38,35 ± 2,55 N/cm2 and that is well coordinated with the available literary data. The received results can be used in developing a rapid method of determining the adhesion of the VACNT array by atomic force microscopy, as well as to create biomimic adhesive structures on the basis of vertically aligned carbon nanotubes.
