Boron containing materials as novel classes of antibacterial agents have been widely used in coating or medical applications due to their excellent functionality against microorganisms. In this study, two different boron dipyrromethene (BODIPY)/zinc oxide based P(M1‐co‐Edot)/ZnO and P(M2‐co‐Edot)/ZnO nanocomposite copolymer materials were prepared. The BODIPY/ZnO nanocomposite films were synthesized using potentiostat. ZnO nanoparticles were used to increase the strength and conductivity of the obtained semiconducting materials. Spectroelectrochemical analysis show that the copolymers, P(M1‐co‐Edot)/ZnO and P(M2‐co‐Edot)/ZnO, have electronic band gaps at 1.56 and 2.51 eV and optical band gaps at 2.11 and 2.00 eV, respectively. The synthesized nanocomposite films were characterized by Raman, nuclear magnetic resonance (NMR) and FT‐IR spectroscopies. The optical properties of the synthesized monomers and their nanocomposite copolymers were demonstrated using UV‐Vis and fluorescence spectroscopy. SEM and AFM images show the surface morphologies of nanocomposite copolymer films and surface roughness of P(M1‐co‐Edot)/ZnO and P(M2‐co‐Edot)/ZnO were calculated as Ra = 84.6 nm Rq = 106 nm and 120 nm, respectively. Antibacterial activities of the obtained nanocomposite films prepared in ultrapure water with different concentrations (2.5‐0.25 mg/mL) were discovered against Gram positive (Staphylococcus aureus) and Gram negative (Escherichia coli) bacteria by using disc diffusion method. The antibacterial activities of obtained films were found to be higher against Gram negative bacteria compared to that of Gram positives. Obtained results show that synthesized nanocomposites with easy production and nontoxic properties can be used as functional bioengineering materials for antibacterial electrochromical materials.

两种新型EDOT-BODIPY氧化锌纳米复合材料的电聚合及其体外抗菌活性评估

含硼材料作为新型抗菌剂,由于其对微生物的优异功能而被广泛用于涂料或医学应用中。在这项研究中,制备了两种不同的硼二吡咯亚甲基(BODIPY)/氧化锌基P(M1-co-Edot)/ ZnO和P(M2-co-Edot)/ ZnO纳米复合共聚物材料。使用恒电位仪合成BODIPY / ZnO纳米复合膜。ZnO纳米颗粒用于增加所获得的半导体材料的强度和电导率。光谱电化学分析表明,共聚物P(M1-co-Edot)/ ZnO和P(M2-co-Edot)/ ZnO的电子带隙分别为1.56和2.51 eV,光学带隙分别为2.11和2.00 eV。合成的纳米复合薄膜的特征在于拉曼光谱,核磁共振(NMR)和傅立叶变换红外光谱。使用紫外可见光谱和荧光光谱法证明了合成单体及其纳米复合共聚物的光学性质。SEM和AFM图像显示了纳米复合共聚物薄膜的表面形态以及P(M1-co-Edot)/ ZnO和P(M2-co-Edot)/ ZnO的表面粗糙度,计算为Ra = 84.6 nm Rq = 106 nm和120纳米。发现在不同浓度(2.5-0.25 mg / mL)的超纯水中制备的纳米复合膜的抗菌活性对革兰氏阳性(SEM和AFM图像显示了纳米复合共聚物薄膜的表面形态以及P(M1-co-Edot)/ ZnO和P(M2-co-Edot)/ ZnO的表面粗糙度的计算公式为Ra = 84.6 nm Rq = 106 nm和120纳米。发现在不同浓度(2.5-0.25 mg / mL)的超纯水中制备的纳米复合膜的抗菌活性对革兰氏阳性(SEM和AFM图像显示了纳米复合共聚物薄膜的表面形态以及P(M1-co-Edot)/ ZnO和P(M2-co-Edot)/ ZnO的表面粗糙度,计算为Ra = 84.6 nm Rq = 106 nm和120纳米。发现在不同浓度(2.5-0.25 mg / mL)的超纯水中制备的纳米复合膜的抗菌活性对革兰氏阳性(金黄色葡萄球菌)和革兰氏阴性(大肠埃希氏菌)细菌采用圆盘扩散法。发现所获得的膜对革兰氏阴性细菌的抗菌活性高于革兰氏阳性细菌。所得结果表明,具有易于生产和无毒性质的合成纳米复合材料可用作抗菌电致变色材料的功能性生物工程材料。
