摘要：
Datura metel L. leaf extract mediated sodium alginate polymer membrane was successfully made using the so-lution 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 x 10-4 Scm � 1, 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 patho-gens. 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.
