Compression and Structure of Monolayers of Charged Latex Particles at Air/Water and Octane/Water Interfaces

摘要: We have studied the compression and structure of compressed monolayers sulfate polystyrene latex particles on air/water octane/water interfaces. If sufficiently (on a Langmuir trough) at surfaces give rafts hexagonally packed particles, while those oil/water interfaces undergo transition from originally hexagonal to rhombohedral structure. found that beyond collapse particle both fold corrugate, there is no expulsion individual or aggregates interface. In case interfaces, structuring (below collapse) was be very sensitive electrolyte concentration in aqueous phase. At low concentration, fairly ordered resulting interparticle repulsion observed, high form 2D clusters. marked contrast, mono...
