表面张力与静电吸附有什么必然关系吗?你的意思是材料表面是否容易静电吸附灰尘，取决于材料的导电性，而非表面的表面张力。是这样？... 既然您提到 [材料表面是否容易静电吸附灰尘] 这么想吧: 1. 塑料尺还是铁尺容易产生静电吸附灰尘???2. 铁尺要在什么条件之下才会带静电? 毫无疑问的, 问题 1 根据生活经验中观察到的结果是塑胶尺容易产生静电吸附灰尘.??问题 2 就有些难了, 如果用手拿着塑胶尺与铁尺磨擦毛衣, 那铁尺是几乎不可能像塑胶尺一样的吸引碎纸片. 为什么? 因为手是导体, 铁尺也是导体, 铁尺上全部的静电立刻顺着手脚接地. v.s. 手是导体, 塑胶尺不是导体, 塑胶尺上的静电只有被手指捏住的部份顺着手脚接地而不带电, 其余部分仍然带着静电.回到问题 2: 如果把铁尺插在一块石蜡上, 那么铁尺带的静电无法通过石蜡接地而溢散, 自然铁尺(在绝缘良好的状况下)也能带静电.吸附的极致, (沒带静电!!)http:///wiki/dry_gluein 2007, researchers from the university of akron and rensselaer polytechnic institute announced they had developed a form of flexible, reusable gecko tape using carbon nanotubes to create microscopic synthetic setaeand spatulae capable of supporting a shear stress of 32 n/cm2, which is four times the strength of a gecko's foot.[4]in 2008 researchers from the university of dayton reported a gecko glue capable of supporting 100n/cm2, ten times the strength generated by a gecko's foot. the research also used carbon nanotubes, but included a curled end which allowed stronger binding but easy removal.[5] defense advanced research projects agency (darpa) has a project called "z-man" that is attempting to develop a fabric allowing soldiers to scale vertical walls while carrying a full combat load.[6] in february, 2012 nitto denko developed a version of gecko tape capable of sticking at temperatures between -150 and 500°c.[7]，查看更多
