本工作发展了一种简便的化学气相沉积(CVD)方法，用分子尺寸的聚二甲基硅氧烷(PDMS-GNSS)修饰石墨烯纳米片。研究了表面改性对GNSS微观结构和分散性的影响及其作为防腐颜料的性能。实验结果表明，PDMS-GNSS的形貌与GNSS相似，厚度比GNSS增加0.23 nm，在常见涂料溶剂中的分散性显著增强，并能增强环氧涂层的防腐性能。该方法在防腐领域具有广阔的应用前景。
A facile chemical vapor deposition (CVD) method is developed to modify graphene nanosheets with molecular-sized polydimethylsiloxane (PDMS-GNSs) in this work. Influences of the surface modification on microstructure and dispersibility of GNSs, as well as their performance as anticorrosion pigments, have been investigated. The experimental results show that the morphology of PDMS-GNSs is similar to that of GNSs, the thickness of PDMS-GNSs increases 0.23 nm as compared to GNSs, and PDMS-GNSs exhibit a significantly enhanced dispersibility in common paint solvents and ability to reinforce the anticorrosion performance of epoxy coating. This method has wide application prospects in anticorrosion field.
