Silk fibroin (SF)-based materials attract significant interest because of their biocompability and great diversity possible morphologies. One the approaches to obtain SF is use an air-water or oil-water interface as a template for protein self-assembly. Surfactants can change surface properties adsorbed layers by promoting preventing formation fiber networks. This study focuses on influence two typical ionic surfactants, cationic cetyltrimethylammonium bromide (CTAB) anionic sodium dodecyl sulfate (SDS), dynamic at interface. The elasticity, tension, ellipsometric angle Δ, film thickness were measured function age surfactant concentration. morphology was evaluated atomic force microscopy (AFM). For adsorption globular proteins, main effect surfactants consists in unfolding high concentrations decrease electrostatic barrier. In case layers, CTAB SDS strongly aggregation Regardless sign charge, its addition solutions results elasticity destruction ordered structure fibers higher than 1 × 10-4 M. With further increase concentration, thread-like aggregates disappear, packing thin becomes less tight, uniform layer disintegrates into separate islands, finally, displaced from
