Method & Evidence

AimTo investigate the use of chromonic liquid crystals in all-aqueous emulsions as templates for the preparation of silica nanomaterials with controlled microporous structures.
MethodExperimental synthesis and characterization
ProcedureResearchers prepared all-aqueous water-in-water (W/W) emulsions using a perylene-based chromonic liquid crystal and a hydrophilic polymer. These W/W emulsions were then emulsified in either another aqueous phase or hexadecane to form three-phase multiple emulsions with various morphologies. Finally, a sol-gel reaction was performed within the liquid crystalline phase of these emulsions to synthesize hollow silica particles with a chromonic-templated microporous structure.
ContextMaterials science and chemical engineering, specifically in the synthesis of nanomaterials.
