摘要: A molecular dynamics simulation was conducted to study the structure and morphology of sodium dodecyl sulfate (SDS) surfactants adsorbed on a nanoscale graphene nanostructure in presence an electrolyte. The self-assembly can be reorganized by electrolyte-induced effect. An increase ionic strength added electrolyte enhance stretching toward bulk aqueous phase make headgroups assemble densely, leading more compact SDS/graphene composite. change is attributed accumulation/condensation cations near surfactant aggregate, consequently screening electrostatic repulsion between charged headgroups. role revealed here provides direct microscopic evidence or explanation reported experiments tuning interfacial aggregate surface carbon nanoparticles. Additionally, t...
