Polyglycidylmethacrylate/polyindole (PGMA/PIN) conducting polymer composites having five different compositions were prepared chemically using FeCl3 as an oxidant agent in chloroform solution and nitrogen atmosphere at 10°C. The conducting polymer composites were characterized by FTIR spectroscopic technique, scanning electron microscopy (SEM), atomic force microscopy (AFM), and thermogravimetric analysis (TGA) measurements. It is seen that morphological structure of composite is different from PIN and PGMA. PGMA/PIN conducting polymer composite including 50% of PIN has a nonuniform and less homogenous structure compared to the PIN and PGMA polymer. in vitro antioxidant activity such as reduction force, superoxide radical removal activity, hydroxyl radical trapping activity, MDA measurements in Saccharomyces cerevisiae cells of PGMA/PIN conducting polymer composite was investigated. It was observed that the reduction force capacities decreased as PIN content and increased due to the percentage of composite of PGMA content. in vitro studies of synthesized composites have shown us that these compounds possess new antioxidant properties.

聚甲基丙烯酸缩水甘油酯/聚吲哚导电聚合物复合材料的合成,光谱表征和体外抗氧化活性。

使用FeCl 3作为氧化剂,在氯仿溶液中和氮气氛下,于10℃化学制备具有五种不同组成的聚甲基丙烯酸缩水甘油酯/聚吲哚(PGMA / PIN)导电聚合物复合材料。通过FTIR光谱技术,扫描电子显微镜(SEM),原子力显微镜(AFM)和热重分析(TGA)测量来表征导电聚合物复合材料。可以看出,复合材料的形态结构不同于PIN和PGMA。与PIN和PGMA聚合物相比,包含50%PIN的PGMA / PIN导电聚合物复合材料具有不均匀且均一性较低的结构。体外抗氧化活性,例如还原力,超氧化物自由基去除活性,羟基自由基捕获活性,MDA测量研究了PGMA / PIN导电聚合物复合材料的酿酒酵母细胞。观察到,还原力能力随着PIN含量的增加而降低,并且由于PGMA含量的复合物的百分比而增加。合成复合材料的体外研究表明,这些化合物具有新的抗氧化性能。
