为了研究聚乙烯工程材料氟化后的表面形貌及耐油性,采用SEM和XPS对经不同氟化浓度氟化的聚乙烯工程材料表面的形貌和元素含量进行了分析,指出在进行氟化反应时不要过度追求氟化层的厚度,而忽略了氟化层表面的均匀程度。另外,耐油性质量损失实验表明,表面氟含量高的聚乙烯工程材料具有较好的耐油性。
In order to study the surface topography and oil-resistant property of polyethylene engineering material after fluorination,the topography and surface’s element content of polyethylene engineering material in different fluorine concentration were analyzed with scanning electron microscopy and X-ray energy dispersive spectrometer.It pointes out that it does not pursue the thickness of fluorinated layer excessively without paying attention to the surface’s homogeneity.Moreover,by oil resistant weight loss experiment,it indicates that the higher surface’s fluorine content of polyethylene engineering material has better oil resistant property.
