- Porous carbon materials with high specific surface areas and superhydrophobicity have attracted much
research interest due to their potential application in the areas of water filtration, water/oil separation, and
oil-spill cleanup. Most reported superhydrophobic porous carbon materials are fabricated by complex
processes involving the use of catalysts and high temperatures but with low throughput. Here, we present a
facile single-step method for fabricating porous carbon nanoparticle (CNP) networks with selective
absorbability for water and oils via the glow discharge of hydrocarbon plasma without a catalyst at room
temperature. Porous CNP networks were grown by the continuous deposition of CNPs at a relatively high
deposition pressure. By varying the fluorine content, the porous CNP networks exhibited tunable repellence
against liquids with various degrees of surface tension. These porous CNP networks could be applied for the
separation of not only water/oil mixtures but also mixtures of liquids with different surface tension levels.
