INTERFACIAL PROPERTY IN NANO-MATERIALS DUE TO VAN DER WAALS AND ELECTROSTATIC COULOMBIC INTERACTIONS

摘要：

The interfacial properties of some nano-materials simulations due to van der Waals and electrostatic Coulombic interactions are investigated using molecular mechanics.Three objects,i.e.,the pull-out process of some outer walls against other nested inner walls in a multi-walled carbon nanotube,the pull-out processes of a carbon nanotube from a polyethylene polymer and an alumina (A12O3) matrices,respectively,are studied.It is found that the pull-out force,is independent of nanotube length,but is proportional to nanotube diameter at the sliding interface.A theory is proposed to predict this pull-out force based on the nanotube diameter at the sliding interface.
