【摘要】 以工业级碱式碳酸锌为原料采用沉淀法制备了ZnO粉体,研究了ZnO粉体在涂料中的抗菌性能,并运用XRD、TEM、Raman等手段对其进行表征。结果表明,本实验制得的ZnO粉体为纳米级,其平均粒径为10nm左右,该材料的粒度分布较均匀且纯度较高。ZnO粉体在涂料中有较好抗菌性能,其含量对抗菌效果有一定的影响,其中以涂料中含3wt.%的ZnO既经济抗菌效果又好。更多还原

【Abstract】 The nanometer ZnO were prepared by precipitation method using basic zinc carbonate(industry grade) as raw material.The influence of the content of nanometer ZnO in dope on resist-bacterium performances were investigated.The prepared samples were characterized by XRD,TEM,Raman.The results show that the prepared ZnO are nano-material and their average grain size is about 10 nm.The granularity of nanometer ZnO is uniform and their purity is higher.The prepared nanometer ZnO has better antibacterial performance and the content of nanometer ZnO in dope affects the antibacterial effect.3 wt.% of nanometer ZnO in dope has better antibacterial effect and economy.更多还原
