Aqueous Foams Stabilized with Several Tens of Micrometer-sized Polymer Particles: Effects of Surface Hydrophilic-Hydrophobic Balance on Foamability and Foam Stability

摘要

40 micrometer-sized polystyrene particles coated by polymer shells with various hydrophilic-hydrophobic balances were synthesized by seeded dispersion polymerization and used as a foam stabilizer. It was confirmed that foamability and foam stability increased with an increase in the hydrophobicity of the polymer particle surface.
