Description
Summary:We report new efficient and cost-effective polymeric bifunctional materials those were evaluated as Cu2+ ions adsorbents and for antimicrobial properties. Two crosslinked polymers were synthesized by thermal polymerization and in situ crosslinking of acrylic acid (AAc) with ethyleneglycol dimethacrylate (EGDMA) or divinylbenzene (DVB) using ammonium persulphate (APS) as initiator. Poly(acrylic acid) [PAAc] was functionalized to improve its efficiency and selectivity in the targeted applications alongwith antimicrobial properties by incorporating thiosemicarbazide (TS) on the –COOH groups. The synthesized three-dimensional crosslinked PAAc–cl–EGDMA and PAAc–cl–DVB were converted to their corresponding esters (–COOCH3) by reflux method and further modified with TS to obtain PATS–cl–EGDMA and PATS–cl–DVB, where ATS stands for thiosemicarbazide acrylate. The synthesized networks were characterized using AFM, SEM, 13C NMR, FTIR, XRD, and EDX studies to evaluate their structure. The presence of TS moieties imparted bifunctional characteristic to the polymers with effective and selective Cu2+ ions adsorption and antimicrobial properties. [Display omitted] •Two new crosslinked polymeric networks, with different crosslinker, were synthesized.•Simple green protocols were followed in synthesis.•These were further functionalized with thiosemicarbazide to induce bifunctional properties.•Evaluated as rapid, highly selective, efficient and reusable Cu2+ ions adsorbents.•These possess appreciable antimicrobial properties.
