疏水界面易受到外界环境如刮擦、磨损等影响,难以保持持久疏水性能。因此,具有自愈合性能的疏水界面的制备成为研究热点。通过聚二甲基硅氧烷与硼酸按照一定的比例反应,其中以异丙醇为溶剂,利用有机硅固有的疏水特性,设计和合成具有聚二甲基硅氧烷网络链和动态硼酸酯交联的薄膜(BA/PDMS),通过浸渍的方式将BA/PDMS处理到载玻片表面,对其表面红外光谱、表面元素分析、接触角、自愈合性能、表面能和稳定性等进行测试。结果表明:BA/PDMS结构具有良好的自愈合性能和良好的化学稳定性。
The hydrophobic interface is easy to be affected by external environment such as scratching and wear,and it is difficult to maintain the lasting hydrophobic properties.Therefore,the preparation of hydrophobic interfaces with self-healing property has became a research focus.By reacting polydimethylsiloxane with boric acid in a certain proportion,isopropanol was used as the solvent to design and synthesize the polydimethylsiloxane network chain and dynamic borate cross-linked coating (BA/PDMS).BA/PDMS was further treated on the surface of slide glass by dripping-drying method,and the surface was tested to evaluate its infrared spectroscopy,surface element analysis,contact angle,self-healing performance and chemical stability.The results showed that the BA/PDMS structure had good self-healing performance,low surface energy and good chemical stability.
