超石墨烯（SG）和超方形（SS）碳纳米管网络由直的单壁碳纳米管和相应的结构成。采用分子结构力学方法研究了碳纳米管网络在不同边界条件下的弹性屈曲行为。结果表明：（a）SG和SS网络的临界屈曲力随网络边长或纵横比的增大而减小。连续体板理论可以很好地预测SS网络的屈曲，但不能预测具有非均匀屈曲模态的SG网络。(b)碳纳米管网络是比具有较少碳原子的石墨烯结构更稳定的结构。(C)2010 Elsevier B.V.保留所有权利。
The super-graphene (SG) and super-square (SS) carbon nanotube network are built by the straight single-walled carbon nanotubes and corresponding junctions. The elastic buckling behaviors of these carbon nanotube networks under different boundary conditions are explored through the molecular structural mechanics method. The following results are obtained: (a) The critical buckling forces of the SG and SS networks decrease as the side lengths or aspect ratios of the networks increase. The continuum plate theory could give good predictions to the buckling of the SS network but not the SG network with non-uniform buckling modes. (b) The carbon nanotube networks are more stable structures than the graphene structures with less carbon atoms. (C) 2010 Elsevier B.V. All rights reserved.
