I. Material Design and Antimicrobial Mechanism

1. Substrate Structure
以Al-Mg-Mn合金Base on Al ≥ 95%, Mg 1.2-2.5%, Mn 1.0-1.8%, throughmicroalloying（添加0.1-0.3% Cu、0.05-0.1% Zn）优化晶界强化效应，结合Nano-ceramic coating(Thickness: 30-50 μm) to form a "metal substrate + functional coating" composite structure.

2. Antimicrobial function implemented

• Ion Implantation TechnologyInject **Ag⁺, Cu²⁺** plasma into the substrate surface (concentration: 5-10 at.%) to disrupt bacterial cell membranes via sustained release;

• 光催化涂层: AdoptTiO₂/石墨烯复合涂层Generates reactive radicals (·OH, O₂⁻) under UV excitation for photocatalytic sterilization.

• 生物基抗菌层：搭载Bamboo fiber/Chitosan（厚度10-20μm）天然抗菌层，通过物理吸附和化学降解抑制微生物增殖。
