Abstract

Poly (vinylidene fluoride) (PVDF) is the first-choice ferroelectric support or membrane material. The lanthanum strontium manganite (LSMO) is a well-known electrode material in the class of the solid oxide fuel cell (SOFC) materials. A set of four polymer composites PVDF-LSMO-PANI(5.0 wt%) with different amount of silver doping were fabricated with the silver nitrate and reducing agent. The characterization of these four novel PVDF based composites were characterized by the XRD, FTIR, SEM, UV-Visible DRS. The present communication highlights: (I) the effect of PANI in the PVDF-LSMO-PANI (PLP) composites towards the photocatalytic degradation of ciprofloxacin drug. (II) the effect of Ag doping in the Ag-PVDF-LSMO-PANI (Ag-PLP) composites towards the photocatalytic degradation of ciprofloxacin drug. It is observed that the incorporation of PANI in PVDF-LSMO and Ag in PVDF-LSMO-PANI polymer ceramic composites showed enhanced photocatalytic degradation of ciprofloxacin in the irradiation of visible radiation. The plausible separation of photo-generated e- hole pairs (e- and h+) carried on by charge migration kind of mechanism is being studied here to understand the improved photocatalytic activity of Ag-PVDF-LSMO-PANI composites.

利用新型 PVDF/聚苯胺/锰酸镧锶@银复合材料光催化降解环丙沙星药物

聚偏二氟乙烯（PVDF）是首选的铁电支撑材料或膜材料。镧锶锰矿（LSMO）是固体氧化物燃料电池（SOFC）材料中一种著名的电极材料。研究人员利用硝酸银和还原剂制备了四种不同银掺杂量的聚合物复合材料 PVDF-LSMO-PANI（5.0 wt%）。对这四种新型 PVDF 基复合材料的表征采用了 XRD、傅立叶变换红外光谱、扫描电镜和紫外-可见 DRS。本通讯重点介绍了：（I）PVDF-LSMO-PANI（PLP）复合材料中的 PANI 对环丙沙星药物光催化降解的影响。(II）Ag-PVDF-LSMO-PANI（Ag-PLP）复合材料中掺入 Ag 对光催化降解环丙沙星药物的影响。研究发现，在 PVDF-LSMO 中掺入 PANI 和在 PVDF-LSMO-PANI 聚合物陶瓷复合材料中掺入 Ag 后，在可见光辐射照射下，环丙沙星的光催化降解能力增强。本文研究了电荷迁移机制下光生成的电子-空穴对（e-和 h+）的分离，以了解 Ag-PVDF-LSMO-PANI 复合材料光催化活性的提高。
