摘要

采用粗颗粒分子动力学(MD)模拟再现了由全氟聚醚(PFPE) Zdol和三官能团PFPE组成的润滑膜的表面形态,三官能团PFPE在分子中间有一个官能团,在分子的头部和尾部有一个官能团。介绍了分子网格扫描法检测薄膜表面位置的方法。研究了具有周期性边界条件的平坦固体表面上极性基团数目和聚合物长度对润滑膜的影响。结果表明,在相同膜厚条件下,三功能PFPE润滑油的膜面比Zdol 2000光滑。

Evaluation of Morphological Properties of Perfluoropolyether Films on Magnetic Disks Using Molecular Dynamics Simulation
Coarse-grained molecular dynamics (MD) simulations were applied to reproduce the surface morphology of lubricant films composed of perfluoropolyether (PFPE) Zdol and tri-functional PFPE, which has a functional group at the middle of a molecule as well as functional endgroups at the head and tail of the molecule. The molecular-mesh scanning method was introduced to detect the location of film surface. The effects of the number of polar groups and polymer length on a flat solid surface were studied as lubricant films with periodic boundary conditions. We clarified that the film surface of the tri-functional PFPE lubricant was smoother than Zdol 2000 when compared at the same film thickness condition.
