The evaporation loss is one of the long-term serious problems to the storage and transit of the fuel oil, as well as the environment protection. Therefore, it is necessary to develop an economic, low investment, simple and convenient maintenance technology to reduce the evaporation loss, which can be applied to different kinds of condition. To perform this task the surface-fluorinated polymer hollow spheres are designed as the surface-covering layer of the fuel oil to restrict evaporation. A comparison of fuel oil evaporation loss from both surface-fluorinated polymer hollow sphere surface and free fuel oil surface has been done. Experiments show that this technique can reduce about 62.2% of the rate of evaporation loss from fuel oil. It is considered has a wide application perspective, as well as in the efficient use of water in agriculture, industry and drought areas.
