Abstract: The present disclosure relates to a fence having a hydrophilic material, and according to an embodiment of the present disclosure, there is an effect in collecting oil or hazardous & noxious substances quickly and efficiently while minimizing the pressure caused by water, by forming the fence from a material that allows water to penetrate while disallowing oil to penetrate.Additionally, there is an effect in preventing oil spill phenomena caused by damage or unbalance of the fence by reducing the water pressure applied to the fence due to water penetration even when a strong water pressure acts on the fence, for example, strong tidal currents occur and the fence is towed at high speeds to collect oil.

Abstract: Provided is a microplastic recovery material according to an embodiment of the inventive concept including a porous structure including a first hierarchical pocket provided in an outer surface thereof, and a nano-protrusion provided on the outer surface. The first hierarchical pocket includes a first pocket and a second pocket that are connected to each other. The first pocket has a diameter of about 1 mm to about 5 mm. The second pocket has a diameter of about 1 μm to about 100 μm.
