摘要：
This study focused on the application of vertically aligned carbon nanotubes (VACNTs) grown by thermal chemical vapor deposition as a gecko-inspired dry adhesive material. The adhesive properties of VACNTs comprising Fe and Al2O3 layers of different thicknesses were evaluated by scanning electron microscopy, Raman spectroscopy, transmission electron microscopy, and atomic force microscopy. Owing to the surface energy difference between metallic Fe and alumina, the wetting influence of the latter enabled the conversion of the iron film into metal islands (nanoparticles) at high temperature. The bionic morphological characteristics of the produced VACNTs (e.g., alignment, density, diameter, growth rate, and defects) and thus their adhesive properties were determined by the size and distribution of the catalyst particles. With respect to variable adhesion test angles, VACNTs were sensitive to peeling angles and showed high tangential but low normal adhesion strength, thereby providing controlled strong adhesion characteristics in combination with easy peel-off.
