With our approach, hollow nanorods or nanofibers with controlled diameter and length are prepared on polymer surfaces. The whole fabrication process is completed in ~30 s and equally applicable to polymers of different crystalline structures. The wettability of the as-fabricated polymer surfaces (being hydrophilic, hydro- phobic, highly hydrophobic or even superhydrophobic) is readily regulated by adjusting the welding time from 0 s to a maxi- mum of 10 s. Our approach can be a promising industrial basis for manufacturing functional nanomaterials in the fields of electronics, optics, sensors, biology, medicine, coating, or fluidic technologies.展开更多
