The preparation of copper oxide (CuO) microspheres was done via hydrothermal route with the amphiphilic polymer pluronic (P123) as the capping agent. The XRD studies confirmed the monoclinic structure of the compound. The formation of microspheres were confirmed through SEM and TEM studies. The pseudo-capacitance properties were inferred with three electrode system. The cyclic voltammetry studies were done for the scan rates of 5 to 100 mV/Sec. The charge-discharge analysis was done for different current density values of 1 to 20 A/g. The specific capacitance of the material for a current density value of 1 A/g was found to be 245 F/g. The cytotoxicity study of the CuO microspheres studied using MTT assay shows the material to be non-toxic in nature.

用于伪电容器应用的氧化铜微球及其细胞毒性研究

以两亲性聚合物普朗尼克（P123）为封端剂，通过水热法制备氧化铜（CuO）微球。XRD 研究证实了该化合物的单斜结构。通过SEM和TEM研究证实了微球的形成。用三电极系统推断赝电容特性。循环伏安法研究是针对 5 到 100 mV/秒的扫描速率进行的。对 1 至 20 A/g 的不同电流密度值进行充放电分析。发现电流密度值为 1 A/g 时材料的比电容为 245 F/g。使用 MTT 法研究的 CuO 微球的细胞毒性研究表明，该材料本质上是无毒的。
