Excess free radicals can have some negative effects on human health. In this paper, a nanozyme was successfully constructed by the coordination of copper ions and tannic acid, its structure elemental distribution were determined Fourier transform infrared spectroscopy, scanning electron microscopy X-ray photoelectron spectroscopy. Free radical scavenging experiments confirmed that it possessed superoxide dismutase-like activity, catalase-like hydroxyl ability. The results thermogravimetric analysis demonstrated good thermal stability. A polyacrylonitrile hybrid nanofibrous membrane loaded with Cu/TA electrospinning technology, maximum rate DPPH ABTS reach 64.22% 58.44%, respectively. nanofiber also exhibited ability to protect cells from oxidative stress damage. Therefore, has broad application prospect in fields such as food preservation biomedicine.
