摘　　要：采用不同类别的离子表面活性剂对氧化石墨烯(GO)进行功能化修饰,并通过溶液共混法制备了一系列聚乙烯醇缩丁醛/功能氧化石墨烯(PVB/f-GO)复合材料。X射线衍射仪(XRD)、原子力显微镜(AFM)和透射电子显微镜(TEM)分析表明,表面活性剂的插入有效阻止了GO的聚集,改善了其在PVB中的分散性。力学性能和可见光区透光性能测试表明,当添加十六烷基磺酸钠改性的氧化石墨烯(s-GO)含量为0.02 wt%时,PVB/s-GO复合材料的拉伸强度相比于原始PVB提高了38.1%,同时保持着88%的可见光透过率;当添加十六烷基苯磺酸钠修饰的氧化石墨烯(sd-GO)含量为0.03 wt%时,PVB/sd-GO复合材料的拉伸强度相比于原始PVB提高了28.4%,紫外线屏蔽能力提高至65%以上。Different ionic surfactants were applied in this work to modify graphene oxide(GO).Then,a series of functionalized-graphene-oxide@polyvinylbutyral(PVB/f-GO)composites were prepared via the solution blending method.The X-ray diffractometer(XRD),atomic force microscopy(AFM)and transmission electron microscopy(TEM)analyses revealed that the surfactant insertion effectively prevented the aggregation of GO and improved its dispersibility in PVB.The mechanical and optical measurements showed that when 0.02 wt%sodium hexadecyl sulfonate modified graphene oxide(s-GO)was added,the tensile strength of PVB/f-GO composite material was 38.1%higher than that of pristine PVB,while the visible light transmittance was maintained at 88%.When the sodium hexadecylbenzene sulfonate modified graphene oxide(sd-GO)content was 0.03 wt%,the tensile strength of PVB/sd-GO composite materials was increased by 28.4%compared to that of pristine PVB,while the ultraviolet shielding ability was increased above 65%.
