The　pull-out　process　of　the　carbon　nanotube　from　polyethylene　was　simulated　by　molecular　dynamics　method.　A　model　of　a　carbon　nanotube　in　polyethylene　was　established.　In　the　simulation,　Adaptive　Intermolecular　Reactive　Empirical　Bond　Order(ARIEBO)　potential　was　adopted　to　describe　the　interaction　of　C-C　and　C-H　in　the　carbon　nanotube　and　polymer,　and　Lennard-Jones　pair　potential　was　used　to　describe　the　interaction　between　the　carbon　nanotube　and　polymer;　NVT　ensemble　was　adopted　in　the　whole　simulation　and　Nose-Hoover　method　was　used　to　control　the　temperature　at　absolute　zero,　which　avoided　the　influence　induced　by　thermal　activation;　Verlet　algorithm　was　used　to　solve　molecular　dynamics　equations　in　the　procedure　of　simulation.　The　deformation　and　forces　on　interfaces　between　the　carbon　nanotube　and　polymer　was　analyzed　by　simulating　the　process　of　pulling-out　of　the　carbon　nanotube　from　polyethylene.
