摘要: Vibration reduction is of great importance in various engineering applications, and a material that exhibits good vibration damping along with high strength modulus has become more vital. Owing to the superior mechanical property carbon nanotube (CNT), new types can be developed. This paper presents recent advancements, including our progresses, development high-damping macroscopic CNT assembly materials, such as forests, gels, films, fibers. In these assemblies, structural deformation CNTs, zipping unzipping at connection nodes, strengthening welding sliding between CNTs or bundles are playing important roles determining viscoelasticity, elasticity well. Towards enhancement, strategies for micro-structure interface design also discussed.
