Datura metel L. leaf extract mediated sodium alginate polymer membrane was successfully made using the solution casting technique. Electric, electrochemical, physicochemical and antimicrobial analyses of the prepared film were investigated. Functional groups of polysaccharides are identified in FTIR analysis and crystallinity/amorphous of the prepared samples was studied using XRD analysis. The prepared polymer membrane (DmMSA2) exhibits the ionic conductivity of 2.18 × 10 Scm, maximum specific capacitance of 131 F/g at a current density of 0.2 A/g and also exhibits a significant effect of antimicrobial activity against human pathogens. Hence, Datura metel L. leaf extract mediated polymer membranes are promising candidates for solid-electrolyte in supercapacitor devices and antimicrobial agents in food packaging applications.
利用溶液浇铸技术成功制备了曼陀罗叶提取物介导的海藻酸钠聚合物膜。对所制备薄膜的电学、电化学、物理化学和抗菌性能进行了分析。傅里叶变换红外光谱分析鉴定了多糖的功能基团，X 射线衍射分析研究了样品的结晶/非晶态。所制备的聚合物膜（DmMSA2）在电流密度为 0.2 A/g 时具有 2.18×10 Scm 的离子电导率和 131 F/g 的最大比电容，并表现出对人体病原体的显著抗菌活性。因此，曼陀罗叶提取物介导的聚合物膜有望成为超级电容器器件中的固体电解质和食品包装应用中的抗菌剂。
