类金刚石（DLC）薄膜的摩擦学和表面特性的奇异性，适合于自组装应用。通常，DLC薄膜已被开发为用于具有相对运动的滑动表面的保护涂层。但是，沉积在纳米结构表面上的DLC涂层也为自组装应用提供了新的潜力。特别地，在通过脉冲DC等离子体增强化学气相沉积（PECVD）沉积的DLC的沉积期间添加氟对表面能和摩擦学特性具有显著影响，这加速了自组装过程中所涉及的机制。在DLC涂层的多种应用中，我们还发现了其生物相容性和抗血栓性。这些特性使它们成为许多医疗应用的候选者，其中需要耐磨涂层，例如假体或简单的生物相容性部件。
The singular characteristics of diamond-like carbon (DLC) thin films, concerning tribological and surfaces properties, are suitable for self-assembly applications. Usually, DLC thin films have been developed as protective coatings for sliding surfaces with relative motion. But, DLC coatings deposited on nanostructured surfaces also provide new potential for self-assembly applications. In particular, the addition of fluorine during the deposition of DLC deposited by pulsed DC plasma enhanced chemical vapor deposition (PECVD) has a significant effect on the surface energy and tribological characteristics, which accelerates the mechanisms involved in self-assembly processes. Among the multiple applications of DLC coatings we also found their biocompatibility and antithrombogenicity. Such properties make them candidates for a number of medical applications where wear-resistant coatings, such as prosthesis, or simply biocompatible parts are required.
