Strategies to modify chromium nitride (CrN) surfaces are important because of the increasing applications of these materials in various areas such as hybrid electronics, medical implants, diffusion barrier layers, corrosion inhibition, and wettability control. The present work presents the first surface immobilization of alkyl and perfluoro-alkyl (from C6 to C18) chains onto CrN substrates using appropriately functionalized 1-alkynes, yielding covalently bound, high-density organic monolayers with excellent hydrophobic properties and a high degree of short-range order. The obtained monolayers were characterized in detail by water contact angle, X-ray photoelectron spectroscopy (XPS), ellipsometry, and infrared reflection absorption spectroscopy (IRRAS).
由于这些材料在混合电子、医疗植入物、扩散阻挡层、腐蚀抑制和润湿性控制等各个领域的应用日益增多，因此，对氮化铬 (CrN) 表面进行改性的策略非常重要。本工作首次使用适当官能化的 1-炔烃将烷基和全氟烷基（C6 至 C18）链表面固定在 CrN 基底上，得到了共价键合的、具有高密度、优异疏水性和高度短程有序的有机单层。通过水接触角、X 射线光电子能谱 (XPS)、椭圆光度法和红外反射吸收光谱 (IRRAS) 对获得的单层进行了详细表征。
