Tuning Surface Tension Properties of Aqueous Scleroglucan Solutions via Chemical Modification

Hydrophobic stearate and sodium carboxymethyl groups were grafted onto the hydroxyl functions of scleroglucan (Scl) to modify Scl amphiphilic properties. The structures of the samples were studied by FTIR. Also, drop weight method was used to investigate surface tensions of the modified Scls solutions. The results showed that hydrophobic stearate groups were more efficient than sodium carboxymethyl groups indeveloping aqueous solutions with amphiphilic properties and lower surface tensions. Finally, the synthesized amphiphilic samples can have potential applications in formulation as EOR agents
