摘　　要：The plastic pollution has become one of the top environmental concerns.Substantial effort has been devoted into recycling waste plastic materials in a facile and economical way.In this work,we have successfully recycled a common type of plastic waste,i.e.,polystyrene(PS),into value-added functional materials through a cost-effective and facile dip-coating method.The resulted mixture of waste PS and SiO_(2),referred to as PS/SiO_(2),coated textile material is superhydrophobic and superoleophilic,showing an excellent resistance towards corrosive solutions(acid,alkaline,and saline),high temperature treatment,and mechanical abrasion.As a proof-of-concept application,the PS/SiO_(2)-coated textile is used to selectively separate oil/water mixtures through either absorption or filtration method.It also exhibits a surface self-cleaning property,which may be used as fabrics for dust-preventing cloths.Our work offers a new strategy to treat the waste for preparation of novel low-cost superhydrophobic materials for various applications.
