摘　　要：利用Langmuir-Blodgett技术制备氧化石墨烯Langmuir单层及多层膜,由单分子层表面压力(π)-面积(A)等温线,来探讨单分子膜在气/液界面的行为。采用布鲁斯特角显微镜研究了氧化石墨烯在水/空气界面的界面性能,并使用紫外可见光谱、傅里叶变换(FT-IR)分析了氧化石墨烯的LB多层膜。结果显示,氧化石墨烯在气液界面能形成稳定的单层膜,并且可以成功的转移到固体基片形成LB多层膜。in this paper,graphene oxide Langmuir monolayer and multilayer films were prepared by Langmuir-Blodgett technology. the behavior of monolayer at gas/liquid interface was investigated by surface pressure( π)--area( A) isotherms of monolayer. the interfacial properties of graphene oxide at the water/air interface were investigated using a brewster angle microscope. the LB multilayer films of graphene oxide were analyzed by uv-vis spectroscopy and fourier transform( FT-IR). As a result,graphene oxide can form a stable monolayer at the gas-liquid interface and can be successfully transferred to the solid substrate to form LB many.
