Abstract:

The self-assembly was induced for a hydrophilic random copolymer of poly(DMAEMA-co-AA) in pure water, and the self-assemblies were fabricated by loading antibacterial active components. The results indicated that when the random copolymer contained 51.6 wt % of AA, poly(DMAEMA-co-AA) tended to form spherical and porous spherical self-assemblies in pure water. With an increase of pH value, the self-assemblies exhibited a “breathing” behavior and varied from small-size spheres to porous spheres. More than 85 % ethyl p-hydroxybenzoate sodium as an antibacterial component could be stably loaded on the self-assemblies to form the antibacterial nanomaterials. Moreover, the other antibacterial components could also be loaded on the self-assemblies. The antibacterial nanomaterials achieved a logarithmic antibacterial value of above 4.4, and they could prolong the storage time of food at room temperature when used for anti-bacterial packaging.

Key words: purely hydrophilic random copolymer, aqueous self?assembly, antibacterial material, active load technique
