论文摘要
研究了一个简单的模型，该模型研究了流经亚纳光直径碳纳米管的一维水链经历的摩擦。该模型基于由于链的运动而导致的纳米管和水链中的声子和电子激发引起的刺激和电子激发，因此水链经历的摩擦的最低级扰动理论处理。在此模型的基础上，我们能够证明，如果纳米管是金属的，则可以考虑通过碳纳米管通过碳纳米管的观察到的水链流速。但是，如果是绝缘的，我们的计算表明，在水流通过亚纳米直径纳米管的实验研究中，水的流速可能会大得多。
A simple model for the friction experienced by the one dimensional water chains that flow through subnanometer diameter carbon nanotubes is studied. The model is based on a lowest order perturbation theory treatment of the friction experienced by the water chains due to the excitation of phonon and electron excitations in both the nanotube and the water chain, as a result of the motion of the chain. On the basis of this model, we are able to demonstrate that the observed flow velocities of water chains through carbon nanotubes of the order of cm/s can be accounted for, if the nanotube is metallic. If it is insulating, however, our calculations imply that the flow velocity of the water could be much larger for the pressure gradient in experimental studies of water flow through subnanometer diameter nanotubes.
