摘要
以头发纤维(HHF)为基材,十八烷基三氯硅烷(OTS)为改性剂,通过浸涂法使十八烷基三氯硅烷(OTS)水解、自组装、缩聚产生的聚十八烷基硅氧烷(PODS)自组装层附着在头发纤维表面,合成具有疏水/亲脂特性的头发纤维。使用红外光谱、扫描电镜、能谱分析仪及接触角测量仪对其表征,并研究改性头发纤维的吸油率及油水分离性能。结果表明:PODS成功附着在头发纤维表面,水在改性前后头发纤维的接触角分别为70°和142°。改性头发纤维在纯油系统对蓖麻油、机油、甲苯和氯仿的最大吸油率分别为11.5、6.1、3.1和2.0g/g。同时,改性头发纤维具有良好的油水分离能力,较好的重复利用性能。
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,11.5 g/g;engine oil,6.1 g/g;toluene,3.1 g/g;petroleum ether,2.0 g/g.The oil/water separation study proved that modified human hair fiber had good oil and water separation ability and great property of reusability.
