摘要
针对面向5G通信光缆应用的钢塑复合带界面结构和连接机制开展研究,利用接触角测量仪、白光干涉仪对镀铬钢原始表面性能进行分析。结果表明,镀铬钢表面具有一定的润湿性和粗糙度;同时利用扫描和透射电子显微镜对复合带的横截面进行微观表征,结果表明镀铬钢与乙烯丙烯酸(EAA)塑料薄膜之间通过金属氧化层实现连接紧密,并形成微观机械咬合。此外,利用扫描电子显微镜、X射线光电子能谱等对剥离测试之后的镀铬钢表面进行表征,进一步分析发现,镀铬钢表面铬的氧化层与EAA中的羰基反应生成-C-O-Cr化学键。综上所述,微观机械咬合和化学键合是钢塑复合带界面的重要连接机制。
The study was to clarify the interfacial structure and bonding mechanisms of chromium coated steel-EAA strip for 5G communication optical cable application.The original metal surface was analyzed by contact angle measurement and scanning white light interferometer.The results show that the surface of chromium coated steel is hydrophilic and rough.Electron microscopies were used to characterize the cross sections of the laminated strip.It is found that chromium coated steel and ethylene acrylic acid(EAA)plastic film are tightly bonded through metal oxide layer with the formation of microscale mechanical interlocking.In addition,the fractured surface of chromium coated steel after peeling test was analyzed by scanning electron microscopy(SEM)and X-ray photoelectron spectroscopy(XPS).Further analyses show that the chromium oxide layer is chemically bonded to the carbonyl group in EAA in the form of C-O-Cr.In summary,the microscale mechanical interlocking and chemical bonding are important interfacial bonding mechanisms of chromium coated steel-EAA polymer strip.
