Polyampholyte (PA) hydrogels are a fascinating class of soft materials that can exhibit high toughness while retaining self-healing characteristics. This behavior results from the random distribution of oppositely charged monomers along the polymer chains that form transient bonds with a range of bond strengths. PAs can be dissolved in aqueous salt solutions and then recast via immersion precipitation, making them particularly useful as surface coatings in biomedical applications.

Article Synopsis
- High-flux filtration membranes that are both scalable and sustainable are needed for energy-efficient separations, but achieving this often poses challenges.
- This study presents a new method for creating polyelectrolyte complex (PEC) membranes using simple aqueous processing, allowing for control over their porosity and stability in various environments.
- PECs, made from oppositely charged polymers, can be swiftly synthesized and show great potential for both water and solvent filtration applications due to their enhanced electrostatic stability in organic solvents.
Article Synopsis
- Polyelectrolyte complex (PEC) films, made from oppositely charged polymers, have important uses in drug delivery, separation membranes, and biocompatible coatings.
- Traditional methods for creating these films are slow and complicated, requiring multiple steps to achieve desired thicknesses.
- This research introduces a fast one-pot electrochemical method to create 1 μm PEC films in just 5 minutes by utilizing hydrogen peroxide reduction, improving the efficiency and potential applications of PEC coatings.
