研究目的
Investigating the synthesis, structural, morphological, and electrical properties of CuO@Alginate nanocomposite and pure CuO nanoparticles.
研究成果
The synthesis of CuO and CuO@Alg nanocomposite using the sol-gel method was successful, with an average crystallite size of 18.93 nm confirmed by XRD, SEM, and TEM analysis. The dielectric constant decreased with increasing frequency, while AC conductivity showed an upward trend. The CuO@Alg nanocomposite exhibited better electrical properties than pure CuO.
