Fabrication of porous cone by temporal-spatial shaping femtosecond laser-assisted molding

A new method for fabricating porous cone by temporal-spatial shaping femtosecond laser–assisted molding is proposed. In this method, high-depth micro cone arrays can be efficiently fabricated by Bessel beam with long focal depth. besides, combining with sugar to be sacrificed, porous cone can be molded with the fabricated cone template. Furthermore, hydrophilic bottom layer is realized with the Hydrophilic treatment by Poly-dopamine. This may have potential applications in Solar-driven seawater desalination.
