Recently, development of molecular mashine, acting in a scale of molecular assembly, have started based on usage of probe microsocpy. In this project, we tried to orient uniaxially dipole moments in a polyoxymethylene chain by applying electric field in order to develop a novel actuator (molecular piston).A benzene solution of polyoxymethylene was spread on water surface to prepare the polyoxymethylene monolayr. The monolayr was prepared by changing the concentration of spread solution, the surface pressure, the compression speed and the subphase temperature. The monolayr was transfeercl onto mica substrate to observe the morphology by an atomic force microscope. The morphologically homogeneous polyoxymethylene monolayr was prepared by the compression speed of 0.8 mm/s the surface pressure of 20 mN/m and at the subphase temperature of 293 K by using the solution with the concentration of 10^3 M.An isolated polyoxymethylene chain was obtained by scanning at stronger applied force. The expansion and contraction behaviors of polyoxymethylene chain will be investigated by applying electric field between cantilever and the substrate.

最近，基于探针微社会的使用，以分子组装的量表作用的分子杂种的发展开始。在这个项目中，我们试图通过施加电场来开发新型执行器（Molecular Piston），在聚氧甲基链中单次偶极矩（分子活塞）。多氧甲基的苯溶液在水面上散布在水表面上以制备聚氧甲基烯基元。通过更改扩散溶液的浓度，表面压力，压缩速度和亚相温度来制备单片。将单层转移到云母底物上，以通过原子力显微镜观察形态。通过0.8 mm/s的压缩速度为20 mn/m，在293 K的亚相温度下，通过使用10^3 m.an iman分离的多氧甲基链的溶液在强施加强度的强度时，在293 K的亚相温度下，通过在293 K的亚相温度下，在293 k的亚相温度下，制备了形态上均匀的多氧甲基单甲基。通过在悬臂和底物之间应用电场，将研究聚氧甲基链的膨胀和收缩行为。
