The development of antimicrobial polymers is a priority for engineers fighting microbial resistant strains. Silver ions and silver nanoparticles can assist in enhancing the antimicrobial properties of microcapsules that release such substances in time which prolongs the efficiency of antimicrobial effects. Therefore, this study aimed to functionalize different polymer surfaces with antimicrobial core/shell microcapsules. Microcapsules were made of sodium alginate in shell and filled with antimicrobial silver in their core prior to application on the surface of polymer materials by dip-coating methodology. Characterization of polymers after functionalization was performed by several spectroscopic and microscopic techniques. After the characterization of polymers before and after the functionalization, the release of the active substances was monitored in time. The obtained test results can help with the calculation on the minimal concentration of antimicrobial silver that is encapsulated to achieve the desired amounts of release over time.
开发抗菌聚合物是对抗微生物耐药菌株的工程师们的首要任务。银离子和银纳米颗粒有助于增强微胶囊的抗菌性能，这些微胶囊能及时释放此类物质，从而延长抗菌效果的持续时间。因此，本研究旨在用抗菌核壳微胶囊对不同的聚合物表面进行功能化处理。微胶囊的外壳由海藻酸钠制成，在通过浸涂法应用于聚合物材料表面之前，其核心填充有抗菌银。通过几种光谱和显微镜技术对功能化后的聚合物进行表征。在对功能化前后的聚合物进行表征后，及时监测活性物质的释放情况。所获得的测试结果有助于计算封装的抗菌银的最低浓度，以实现随时间推移所需的释放量。
