Abstract

The Ti6Al4V presented a natural oxide layer that increased the corrosion resistance of the material but decreased the physicochemical compatibility with the bone tissue. The use of polymeric coatings on Ti6Al4V allows the creation of an interface that promotes osseointegration and antibacterial activity. The objective of this work was to analyze a coating on Ti6Al4V obtained by dip-coating with a mixture of chitosan, polycaprolactone, and silver. The synergy between chitosan and silver allows the polymeric matrix to be retained and to enhance the coating’s mechanical-structural functions, integrating bone cells and serving as antibacterial agents. Coating morphology was assessed by scanning electron microscopy (SEM) and the distribution of chemical elements was determined by energy dispersive spectroscopy (EDS). Confocal Raman spectroscopy was used to evaluate the composition and structure of the coating. Electrical potential distribution, phase distribution and surface topography of surfaces were analyzed using an electrostatic force microscopy. Contact angle measurements were also performed to determine coating wettability.

用拉曼光谱、EFM和接触角分析了Ti6Al4V表面聚己内酯-壳聚糖- Ag涂层的关键协同作用

Ti6Al4V呈现出天然氧化层，提高了材料的耐腐蚀性，但降低了材料与骨组织的理化相容性。在Ti6Al4V上使用聚合物涂层可以创建一个界面，促进骨整合和抗菌活性。研究了壳聚糖、聚己内酯和银的混合物在Ti6Al4V表面的浸渍涂层。壳聚糖和银之间的协同作用使聚合物基质得以保留，并增强涂层的机械结构功能，整合骨细胞并作为抗菌剂。采用扫描电镜(SEM)分析涂层形貌，能谱仪(EDS)测定化学元素的分布。利用共聚焦拉曼光谱对涂层的组成和结构进行了表征。用静电力显微镜分析了表面的电位分布、相分布和表面形貌。还进行了接触角测量以确定涂层的润湿性。

期刊介绍： Revista Facultad de Ingenieria started in 1984 and is a publication of the School of Engineering at the University of Antioquia. The main objective of the journal is to promote and stimulate the publishing of national and international scientific research results. The journal publishes original articles, resulting from scientific research, experimental and or simulation studies in engineering sciences, technology, and similar disciplines (Electronics, Telecommunications, Bioengineering, Biotechnology, Electrical, Computer Science, Mechanical, Chemical, Environmental, Materials, Sanitary, Civil and Industrial Engineering). In exceptional cases, the journal will publish insightful articles related to current important subjects, or revision articles representing a significant contribution to the contextualization of the state of the art in a known relevant topic. Case reports will only be published when those cases are related to studies in which the validity of a methodology is being proven for the first time, or when a significant contribution to the knowledge of an unexplored system can be proven. All published articles have undergone a peer review process, carried out by experts recognized for their knowledge and contributions to the relevant field. To adapt the Journal to international standards and to promote the visibility of the published articles; and therefore, to have a greater impact in the global academic community, after November 1st 2013, the journal will accept only manuscripts written in English for reviewing and publication. Revista Facultad de Ingeniería –redin is entirely financed by University of Antioquia Since 2015, every article accepted for publication in the journal is assigned a DOI number.
