分析了聚乙烯高分子材料氟化后化学稳定性增强的原理，并选用经过氟化处理的聚乙烯微球进行了耐油实验。结果表明，经氟化处理后的聚乙烯微球表面形成了一层有效的阻隔层，能够阻止油分子进入微球内部。

The principle of chemical stability enhancement of polyethylene after fluoridation was analyzed. Oil resistance experiment was carried out on polyethylene fluoride microspheres. The results showed that an effective barrier layer forms on the surface of polyethylene fluoride material, which can prevent oil from penetrating inside the material.
