The dynamic behavior of an individual polymer chain in the confined system or environment (the extension of a single polymer chain which one end is fixed under the electric field, the translocation process of a single Gaussian chain through a nanometer-scale pore under the electric field, spontaneous recoil of a single chain located in the confined environment) was studied by using Monte Carlo computer simulation. The simulation results can be used to investigate the kinetic law of molecular chain polarization, dipole relaxation and trapped charge carrier under the application of electric field.

Nanomaterials have many new characterizes which different from the normal materials for their small size, big surface area ratio and quanta dimension domino effect, for examples, the metal with good conductor will be turned into nonmetal when the size is reduced tonanometer levels; the resistance of originally nonconductor will be descended greatly when its size is reduced several nanometers or so, and loss the nonconductor property; the general solid is steady under certain conditions, while under nanometer conditions, the capabilities will be effected greatly by the granule sizes, the newness characteristics made nanomaterials have great appliance foreground on catalyze, optics, and industry produce and so on, therefore the nanomaterials have been the hotspot for materials science, chemistry science and so on.

纳米材料由于尺寸小、比表面积大和量子尺寸效应使它具有不同于常规固体材料的新的特征，如原来是良导体的金属，当尺寸减小到纳米量级时就变成非金属型；原来是绝缘体的物质，当尺寸减小到几纳米或几十纳米时电阻大大下降，失去了绝缘体特性；常规固体在一定条件下物理性能是稳定的，在纳米状态下，颗粒尺寸对性能产生强烈的影响等等，这些新奇的特点使得纳米材料在催化、光学、工业生产等各个方面都有着广阔的应用前景，因此，纳米材料目前已经成为材料科学、物理学及化学等学科的前沿热点。1990年7月在美国巴尔基摩召开了国际第一届纳米科学技术会议，正式把纳米材料科学作为材料科学的一个新的分支公布于世。
