A microwave (MW) assisted process was evolved to synthesize a series of polymer nanocomposites (PNCs) through 2,2-azobisisobutyronitrile (AIBN) initiated free radical in situ polymerization of acrylonitrile (AN) in presence of nanobariumtitanate (NBT). The reaction conditions were optimized and microwave power ranging 25 to 100 W over 10 min was found to be most suited for the synthesis of PNCs. Synthesis of PNCs has been ascertained through UV–vis, FTIR spectroscopy and microstructure were investigated through XRD and AFM. TG-DTA-DTG proclaims that PNCs acquire lower moisture content and higher heat resistance as compared to polyacrylonitrile (PAN). The synthesized PNCs have been applied as sensing material to develop electrochemical probe for detection of doxorubicin (DOX). The presence of DOX (0.01%, w/v) in phosphate buffer at pH 7.4 has shown a remarkable increase in the peak current at PNCs modified glassy carbon electrode (GCE). Cyclic voltammetric (CV) studies pro...

钛酸钡/聚丙烯腈纳米复合材料的合成及表征，用于阿霉素的电化学传感

通过微波（MW）辅助工艺的发展，通过在纳米钛酸钡（NBT）存在下通过2,2-偶氮二异丁腈（AIBN）引发的丙烯腈（AN）自由基自由基聚合来合成一系列聚合物纳米复合材料（PNC）。优化了反应条件，发现在10分钟内25至100 W的微波功率最适合于PNC的合成。已通过紫外可见光确定了PNC的合成，通过XRD和AFM研究了FTIR光谱和微观结构。TG-DTA-DTG宣称，与聚丙烯腈（PAN）相比，PNC具有更低的水分含量和更高的耐热性。合成的PNC已被用作传感材料，以开发用于检测阿霉素（DOX）的电化学探针。pH 7的磷酸盐缓冲液中存在DOX（0.01％，w / v）。图4显示了PNCs修饰的玻碳电极（GCE）处的峰值电流显着增加。循环伏安（CV）研究进展...
