　View Summary

Friction and wear arise in contact sliding parts of machines, increases in wear and deformation of the sliding parts caused by frictional heat. Induce mechanical failure lubricants are used to prevent these problems, but lubricant is evaporated or decomposed by frictional heat. In recent years, ionic liquids are attracting much attention as new lubricants. Ionic liquids have various non-conventional physical and chemical characteristics. We used three types of imidazolium ionic liquids: BMI-PF_6 (1-Butyl-3-methylimidazolium hexafluorophosphate), HMI-PF_6 (1-Hexyl-3-methylimidazolium hexafluorophosphate), OMI-PF_6 (1-Octyl-3-methylimidazolium hexafluorophosphate) with different alkyl chain length. They were coated on Si substrates with SiO_2 layer on the surface. We measured frictional force between the substrate coated with the ionic liquid and AFM (atomic force microscope) conductive tip as voltages were applied between them. It was confirmed that frictional force increased by applying voltages. The sample coated with HMI-PF_6 exhibited the largest increase in frictional force when voltages are applied.

　View Summary

Recently, the self-motion mechanism has attracted attention as a new motion mechanism. By realizing micro self-moving bodies which don't need energy supply from the outside and one equipped with a power source, applications of them to environmental sensing device, and transportation equipments of small objects on water surface, are possible. Since it has been reported that the self-motion on water surface in possible by using an ionic liquid [BMIM][PF_6] (1-butyl-3-methylimidazolium hexafluorophosphate) an a fuel which causes surface tension gradient on water surface and generate propulsion force, we focused on self-motion using ionic liquids. To establish method to control driving force, driving time and moving direction of this micro self-motion mechanism powered by ionic liquids. We measured driving force of a locomotion which has a nozzle to report ionic liquid on water surface and evaluated effects of the shape of the nozzle.

　View Summary

Recentlt, self-motion is attracting attentions as a new motion mechanism that does not require energy supply from outside. Micro self-motion mechanism, in expected to be applied to transportations of small bodies in the water and environmental sensing devices. Among them, driving method using surface tension gradient on water surface are known. By using ionic liquids with ampliphilic chemical structure which can modify surface tention of water surface, the object can be driven by converting chemical energy into mechanical energy directly. We already, confirmed that small objects depositing an imidazolium-based ionic liquid [bmim][PF_6] (1-butyl-3-methylimidaz-olium hexafluorophosphate) moved spontaneously on water surface. In this study, by using a magnetic ionic liquid [bmim][FeCl_4](1-buthyl-3-methylimidazoium Tetrachloroferrate) containing a magnetic anion, we examined a potential application to control the direction of the self-motion by applying magnetic field.
