为提高聚乙烯/木粉复合材料的表面润湿性,采用液相化学氧化方法对聚乙烯/木粉复合材料表面进行处理,利用傅立叶变换红外光谱（FT-IR）、X射线光电子能谱（XPS）、接触角测定以及扫描电子显微镜（SEM）等分析方法研究了不同处理时间复合材料表面性质的变化。结果表明,液相化学氧化处理后,复合材料表面含氧基团增加,有大量的-OH、-C=O基团生成;接触角测试表明,处理后复合材料表面的接触角降低;SEM分析表明,处理后材料表面出现蚀刻的沟槽。
Liquidoid chemical oxidation was used in order to improve the wettability of the surface for polyethylene（PE）/wood composites,and the changes for the surface properties of PE / wood composites under various processing time were studied by Fourier transform infrared spectroscopy（FT-IR）,X-ray photoelectron spectroscopy（XPS）,contact angle and scanning electron microscopy（SEM）.The FT-IR analysis results show that the hydroxyl and carbonyl group are formed on the surface of the treated composites.XPS analysis indicates the content of oxygen element in the composition of surface element for Wood/PE composites increases after treatment.Contact angle measurements indicate that the surface contact angle for the treated composites reduces,showing the wettability is improved after treatment.SEM observation shows that some grooves are appeared on the surface of the treated composites.
