Product description

PDA(Polydopamine) coated Al2O3 particles/PDA-Al2O3 particles/Polydopamine-Al2O3 particles/PDA(Polydopamine) coated alumina particles are aluminum oxide (Al2O3) microspheres or nanoparticles uniformly coated with a polydopamine (PDA) layer formed via dopamine self-polymerization under mild alkaline conditions. The PDA coating imparts surface reactivity, biocompatibility, and functionalization capability while maintaining the core properties of Al2O3.
Applications:
Catalysis supports – PDA layer for anchoring metal nanoparticles.
Biomedical applications – drug delivery, biosensing, or bioimaging.
Functional coatings – anti-fouling, antioxidant, or adhesive layers.
Environmental remediation – adsorption of heavy metals or pollutants.
