Recently, the development of methods for the cleanup of large-scale oil spills or organic pollutants fromwater has been attracting global attention. However, traditional techniques suffer from the limits of lowefficiency and high operation cost. Herein, we propose a high efficiency, large-scale and easy operationapproach to fabricate a hydrophobic and oleophilic high density polyethylene microfiber bundles withinterconnected microchannels for oil/water separation. The microfiber bundles with high porosity, excel-lent absorption capacity and large water contact angle are continuously fabricated by a melt extrusionand leaching technique. More importantly, they are readily cleaned by centrifugation and exhibit excel-lent shape-recoverable property, which are very promising for the cleanup of large-scale oil spills. Thisstudy provides a great promising way to fabricate multifunctional polymer materials by using commonpolymer molding method.
