Article Synopsis
- - Complex coacervation is a process where oppositely charged polymers separate into two phases: one rich in polymers and one poor in them, typically studied in water due to polyelectrolytes' limited solubility.
- - Researchers created two specialized polymerized ionic liquids (PILs), which can dissolve in various organic solvents with different dielectric constants, allowing them to explore how solvent properties affect coacervation.
- - They found that the phase behavior of these PILs is mostly similar across different organic solvents, with only certain protic solvents showing low salt resistance, attributed to strong hydrogen bonding rather than dielectric effects.
Moisture-driven electricity generators (MEGs) have been extensively researched; however, high-performance flexible variants have seldom been demonstrated. Here we present a novel complex coacervation with built-in potential strategy for developing a high-performance uniaxial MEG, featuring a core of poly(3,4-ethylenedioxythiophene) (PEDOT) with a built-in charge potential and a gel shell composed of poly(diallyldimethylammonium chloride) (PDDA) and sodium alginate (NaAlg) coacervate. The complex coacervation of two oppositely charged polyelectrolytes produces extra mobile carriers and free volume in the device; meanwhile, the PEDOT core's surface charge significantly accelerates carrier diffusion.
