采用气流磨处理工业级 Cu2O，可有效减小颗粒粒径和分布范围，得到平均粒径约为 0.98 μm的微纳米 Cu2O；通过抑菌、抑藻、铜离子渗出速率、浅海浸泡等试验探讨了微纳米 Cu2O防污性能。结果表明：相对于工业级 Cu2O，微纳米 Cu2O的 24 h抑菌、抑藻率可分别提升约 28.82%和 21.82%，使防污涂料具有更优异的实海综合应用性能和防污性能；相对于纳米级 Cu2O，基于微纳米 Cu2O的防污涂层具有更稳定、可控的铜离子渗出性能，避免了因纳米 Cu2O引起的前期铜离子“暴释”而导致的资源浪费，以及后期铜离子渗出率不足而导致的防污效果欠佳等缺陷。
The micron-nano size Cu2O with average particle size about 0. 98 μm was produced by jet mill，which could reduce the particle size and distribution range effectively.The anti-fouling performance of micron-nano size Cu2O was studied by anti-microbial test，anti-alga test，measurement of copper ion release rate and anti-fouling test in shallow submergence. The results showed that the anti-microbial rate and anti-alga rate of micron-nano size Cu2O increased by 28. 82% and 21. 82%respectively，comprehensive application performance and anti-fouling performance in anti-fouling coatings for on-site sea test were much better compared to commercial Cu2O. The copper ion release rate of anti-fouling coating based on micron-nano size Cu2O was more stable and controllable compared to nano size Cu2O，avoiding“Over release”of copper ion caused by nano size Cu2O.
