“…A fibrillar adhesive surface based on single-level VA-CNT arrays that exhibited normal and shear adhesion higher than that of a gecko was reported by Qu et al [67]. Several follow-up studies regarding gecko-like adhesives based on VA-CNT have generally confirmed the potential of this approach [68][69][70][71][72][73]. The primary reason for the adhesion enhancement was related to the exceptional mechanical properties of CNT (i.e.…”

The extraordinary adherence and climbing agility of geckos on rough surfaces has been attributed to the multiscale hierarchical structures on their feet. Hundreds of thousands of elastic hairs called setae, each of which split into several spatulae, create a large number of contact points that generate substantial adhesion through van der Waals interactions. The hierarchical architecture provides increased structural compliance on surfaces with roughness features ranging from micrometers to millimeters. We review synthetic adhesion surfaces that mimic the naturally occurring hierarchy with an emphasis on microfabrication strategies, material choice and the adhesive performance achieved.

“…Others have drawn similar conclusions through simulations: the vertical dense arrangement of CNT beams leads to a decrease in adhesion between the CNT beams and the substrate. [ 41 ] Hence, the 500 μm long forest was wholly stripped off under a thick buffer layer, high density, and tip growth route (as shown in Figure ). This has worthwhile value for the application of CNTF as thermal management components and semiconductor components.…”

The stripping of carbon nanotube forests (CNTF) is an urgent problem in terms of its application in thermal management and semiconductor devices. The easy‐peel and vertically aligned CNTF is prepared in a two‐step process of high vacuum magnetron sputtering and chemical vapor deposition. Based on the thick alumina buffer layer, CNTF with heights of 100 μm, 300 μm, and 500 μm was prepared by adjusting the magnetron sputtering power. Through SEM observation and calculation, the corresponding densities were 2.5 × 109 cm−2, 6.4 × 109 cm−2, and 1.21 × 1010 cm−2, with an average curvature of 1.64 × 102 m−1, 1.35 × 102 m−1 and 0.53 × 102 m‐−1, respectively. The TEM, XPS, Raman, and TGA were used to investigate the growth mechanism of CNTF. The experimental results show that the catalyst particles annealed under high sputtering power refined with high density can grow a low‐defect, well‐oriented, and high‐density CNTF, and confirm the tip growth route. Further analysis shows that the easy‐peel properties of CNTF depend on the thickness of the alumina layer, the tip growth route, and the tight entanglement between the nanotubes. This paper provides technical guidance and support for the preparation, stripping, and application of monolithic CNTF.

“…Many researchers have made great efforts. For example, carbon nanomaterials, which have great potential in NEMS, show the ability to tune friction by surface treatment [1][2][3][4], interface structure morphology [5][6][7], and the environmental factors such as temperature [8] and humidity [9]. However, these methods work only under certain situations and a more general method that can tune friction at the nanoscale is still lacking.…”

Abstract:The influence of vibration on friction at the nanoscale was studied via molecular dynamics (MD) simulations. The results show that average friction increases in a high-frequency range. This can be attributed to the vibration of the tip following vibration excitation, which results in peaks of repulsive interaction between tip and substrate and leads to higher friction. However, when the frequency is lower than a certain value, friction decreases. This is because vibration excitation results not in an obvious vibration of the tip but in a slightly larger interface distance, which leads to a decrease in friction.
