高能表面上双组分液滴的运动

Motion of twocomponent droplets on highenergy surface

验证丙二醇(PG)和水混合的双组分液滴在高能载玻片上能够感知彼此并相互移动.搭建尖端放电装置,通过电晕放电方式获得高能载玻片.通过调节液滴浓度、体积与沉积距离,可以观察到液滴间发生“长程吸引”和“短程追逐”现象.利用水、食品色素、载玻片等日常生活材料研制了液滴自对准器及相关设备,为自发传感装置领域提供数据支撑.

It was verified that two-component(propyleneglycol,PG and water)droplets could sense each other and move on highenergy glass slide.A tip discharge device was built to obtain high energy glass slide by corona discharge.By adjustingthe concentration,volumeand deposition distance of the droplets,the phenomenon of“longrange attraction”and“shortrange chasing”could be observed.Based on everyday materials such as food colorants,glass slides and water,droplet self-alignment device and related equipment were developed to provide data support for spontaneous sensor devices.
