摘　　要：配制吸油性与疏水性都良好的试剂,对浒苔进行处理,使其具有亲油疏水性能。结果表明:在焙烘温度100℃的条件下,经10%无氟防水剂处理后,浒苔吸油量为12.7 g/g,为处理前的176%;处理后浒苔吸水量由13.2 g/g降至4.8 g/g,疏水改性的浒苔纤维表现出对油剂较好的吸附性。经三步去盐前处理的浒苔吸油量为14.7 g/g,吸水量降至3.4 g/g;改性后浒苔表面形貌发生变化,出现了饱和烷烃的吸收峰;处理后浒苔水接触角为139.28°,证明成功对浒苔进行吸油疏水表面改性处理。A reagent with good oil absorption and hydrophobicity is prepared to treat enteromorpha to make the enteromorpha with oleophilic and hydrophobic properties.The results show that after oil repellent finish with 10%non-fluorinated water repellent at curing temperature of 100℃,the oil absorption of enteromorpha can reach 12.7 g/g,which is 176%of that before treatment,and the water absorption of enteromorpha decreases from 13.2 g/g to 4.8 g/g with a good adsorption for oil agent.The oil absorption of enteromorpha treated by three-step desalination is 14.7 g/g,and the water absorption decreased to 3.4 g/g.After modification,the surface morphology of enteromorpha changes,and absorption peak of saturated alkanes appeares.The water contact angle after treatment is 139.28°,which proves that the oil absorption and hydrophobic surface modification of Enteromorpha is successful.
