Polydopamine (Pdop) particles possess unique properties but suffer from inherent instability in aqueous environments due to the gradual release of Pdop fragments. This study demonstrated successful enhancement stability and reduction fragmentation through surface engineering strategies. Specifically, we investigated effects polyelectrolyte multilayer (PEM) coating (PE) brush grafting. Our results showed that PE grafting, particularly with long-chain polyethyleneimine (PEI), was more effective suppressing fragment compared PEM coating. The L-PEI grafted (2.28 chains/nm2) exhibited remarkable across a wide pH range (3–9), inhibition rates exceeding 90% most cases, reaching 93% at 5. Furthermore, direct correlation between PEI grafting density (0.64 2.28 rate observed, higher densities yielding greater stability. These findings offer promising approach for stabilizing diverse applications.
