两种平面有序碳纳米管（CNT）网络，超级石墨烯和超级方形碳纳米管网络，理论上是由直的单壁碳纳米管（SWNTs）和相应的碳纳米管结构建的。用分子结构力学方法研究了碳纳米管网络的自由振动。这些具有四个边缘的碳纳米管网络的固有频率仅依赖于边长，而与网络的几何形状和拓扑结构无关。由于连续介质板与这些碳纳米管网络具有相似性，因此可以成功地应用连续介质板的振动理论来解释这些网络的几何和拓扑无关行为。在碳纳米管网络中引入双轴预应变后，这种独立行为仍然存在。
Two kinds of planar, well-ordered carbon nanotube (CNT) networks, Super-Graphene and Super-Square CNT networks, are theoretically built by straight single-walled carbon nanotubes (SWNTs) and corresponding CNT junctions. The free vibrations of these CNT networks are explored by the molecular structural mechanics method. The natural frequencies of these CNT networks with four edges fully clamped are found only dependent on the side lengths but independent of the geometries and topologies of the networks. As the similarity between the continuum plate and these CNT networks, the vibration theory of the plate could be successfully applied to explain the geometry- and topology-independent behaviors of these networks. Such independent behaviors still exist when the biaxial pre-strain is introduced into the CNT networks.
