Structured Liquids with pH-Triggered Reconfigurability

Structured Liquids with pH-Triggered Reconfigurability

Through pH‐tuning of electrostatic interactions between polymer ligands and nanoparticles at structured‐liquid interfaces, liquid droplets can be directed between a jammed nonequilibrium state and a dynamic reconfigurable state. The nanoparticle‐surfactant dynamics highly depend on the pH, so that t...

Zusammenfassung:Through pH‐tuning of electrostatic interactions between polymer ligands and nanoparticles at structured‐liquid interfaces, liquid droplets can be directed between a jammed nonequilibrium state and a dynamic reconfigurable state. The nanoparticle‐surfactant dynamics highly depend on the pH, so that the liquids can be structured using an external field and under variation of pH, or alternatively being realized by remote photo‐triggering.
