• Amphiphilic copolymers
• Modified casein emulsion
• Core-shell structure
• Stability

Casein-based emulsion for film former was innovatively prepared via emulsifier-free emulsion polymerization by employing self-made amphiphilic copolymers (A(m)B(n)C(o)) as the stabilizer. Structure of A(m)B(n)C(o) was confirmed by H-1 NMR spectrometry. Stability of the as-prepared emulsion in different concentrations of A(m)B(n)C(o) was evaluated by measuring their droplet size, microstructure and viscosity. The results indicated that the obtained particles were 40-50 nm in size with uniform size distribution, and exhibited obvious core-shell structure. The emulsion containing 1.0 wt% of A(m)B(n)C(o) presented superior storage stability.
