Abstract

The present invention belongs to the field of synthetic nanomaterials, and in particular to a bionic pine needle nano antibacterial material and its preparation method and application. The particle size of the antibacterial material is uniform, and a single particle is a three-dimensional spike structure composed of 80-300 ZnO nano spikes. The preparation method comprises the following steps: weighing raw materials according to a preset ratio: anhydrous zinc acetate powder, a methanol-based organic solvent, and oleylamine, reacting at a preset temperature to prepare a ZnO bionic nano pine needle solution; purifying the ZnO bionic nano pine needle solution to obtain a ZnO bionic nano pine needle solid powder sample. The present invention prepares a nano antibacterial material with a unique three-dimensional spike structure, uniform size, good dispersibility, and excellent antibacterial performance, and explores its antibacterial application in multiple fields to meet the market demand for efficient, long-lasting, and safe antibacterial materials.
