Microfluidic Generation of Porous Particles Encapsulating Spongy Graphene for Oil Absorption

Porous particles encapsulating spongy graphene are generated from a microfluidic device and used as adsorbents for water treatment. The amphiphilic surface characteristics result from hydrophobic graphene cores and hydrophilic shells and, together with the porous structure, ensure that the particles have the ability to absorb oils that are either floating on the water or under water.
