Abstract: The hydrophobic and oleophilic human hair fiber were synthesized through the hydrolysis of octadecyltrichlorosilane,self-assembly and polycondensation by dip-coating,the PODS self-assemble layers were adhered on fiber's surface.FT-IR,SEM,EDS dispersive spectrometer and contact angle measuring instrument were used to characterize the structure,and the properties of oil absorption and oil/water separation were studied.The results showed that PODS were robust adhere to human hair fiber.The contact angles of raw and modified human hair fiber were 70° and 142°respectively.The maximum oil absorbency of modified human hair fiber was,for Castor oil,11.5g/g;engine oil,6.1g/g;toluene,3.1g/g;petroleum ether,2.0g/g.The oil/water separation study proved that modified human hair fiber had good oil and water separation ability and great property of reusability.
