In this paper, we investigate in detail the electrohydrodynamic spraying of a nonbiodegradable nanocomposite polyhedral oligomeric silsesquioxane polymer developed in our laboratories and currently being explored for coating metallic stent materials. Different concentrations of the polymer have been dissolved to prepare, characterise, and electrohydrodynamically deposit the polymer on stainless steel. From the experiments, the solution containing 15 wt% polymer was selected for further investigation. The variation of film/coating thickness as a function of spraying time was studied and the structural features of the film were assessed using microscopy. Films were also tensile tested. This study has identified a process and conditions which can be used in our stent coating research.
在本文中,我们详细研究了一种在我们实验室开发的、目前正探索用于涂覆金属支架材料的不可生物降解的纳米复合多面体低聚倍半硅氧烷聚合物的电流体动力喷涂。已溶解不同浓度的该聚合物,以制备、表征并通过电流体动力法将聚合物沉积在不锈钢上。通过实验,选择了含15 wt%聚合物的溶液进行进一步研究。研究了膜/涂层厚度随喷涂时间的变化,并使用显微镜评估了膜的结构特征。还对膜进行了拉伸测试。本研究确定了一种可用于我们支架涂层研究的工艺和条件。
