摘要
以石墨为原料,采用Hummers法制备含氧官能团丰富的氧化石墨烯,并选取含有亲水基团的混合纤维膜为基底,采用真空抽滤的方法层层自组装制备氧化石墨烯/混合纤维膜复合膜,并剪裁设计成多种结构的智能驱动器,研究其对有机气体丙酮等的响应性能。详细探讨了复合膜的孔径大小、有机气体种类等对驱动器响应的影响。结果表明,孔径为1.2μm、长度为30 mm、宽度为5 mm的氧化石墨烯/混合纤维驱动器对丙酮响应程度最大,17 s可以弯曲540°;离开丙酮氛围后驱动器恢复原状,表明所得驱动器具有良好的循环使用性能。
Graphene oxide(GO)with rich oxygen functional groups was prepared using graphite as the raw material by Hummers’method.Graphene oxide/cellulose acetate(GO/CA)membrane was fabricated by the vacuum filtration of GO solution on the hydrophilic CA film.Its response to organic gases such as acetone and benzene was studied.The effects of the pore size of the CA membrane and the kinds of the organic solvent on the response of the actuator were investigated in detail.The results show that GO/CA membrane with the pore size of 1.2μm,the length of 30 mm,and the width of 5 mm exhibits the fast response to acetone vapor with the bending of 540°in 17 s,and can be recovered after leaving the acetone atmosphere.GO/CA membrane also exhibits good recycling performance.
