PH CONTROLLED ELECTROCHEMICAL DEPOSITION OF POLYELECTROLYTE COMPLEX FILMS
20180237632 · 2018-08-23 ·

Methods for forming a polyelectrolyte complex (PEC) film are provided. In embodiments, the method comprises applying a potential between a working electrode and a counter electrode, the electrodes in contact with an aqueous polyelectrolyte solution characterized by a bulk pH. The aqueous polyelectrolyte solution comprises a pH sensitive PEC pair comprising an unmodified anionic polymer and a cationic species, an electrochemical pH agent other than water, and a salt. The applied potential induces an electrochemical reaction of the electrochemical pH agent to generate OH.sup. or H.sup.+ at the working electrode without inducing water electrolysis in the aqueous polyelectrolyte solution, thereby forming a PEC film from the unmodified anionic polymer and the cationic species on a surface of the working electrode.

PRECURSOR POLYELECTROLYTE COMPLEXES COMPOSITIONS

The invention relates to compositions and methods of treatment employing compositions comprising polyelectrolyte complexes. The compositions include a water-soluble first polyelectrolyte bearing a net cationic charge or capable of developing a net cationic charge and a water-soluble second polyelectrolyte bearing a net anionic charge or capable of developing a net anionic charge. The total polyelectrolyte concentration of the first solution is at least 110 millimolar. The composition is free of coacervates, precipitates, latex particles, synthetic block copolymers, silicone copolymers, cross-linked poly(acrylic) and cross-linked water-soluble polyelectrolyte. The composition may be a concentrate, to be diluted prior to use to treat a surface.

METHODS OF NANOSCALE DIRECTIONAL WETTING AND USES THEREOF

This invention discloses a method for controlling nanoscopic wetting near or at a molecular scale for synthetic material applications. In particular this invention relates to a method for preparing a monolayer or thin film with a patterned nanoscopic wetting surface using a sitting phase of polymerizable amphiphile, wherein hydrophobic alkyl chains of the amphiphile extend along the supporting surface and the amphiphile molecules align side-to-side, effectively forming a repeating cross-section of bilayer with alternating hydrophilic and hydrophobic stripes of a 6 nm pitch tunable based on the chain length of the amphiphile. Products prepared according to the methods disclosed herein are within the scope of this invention. In some embodiments, monolayers or thin films so prepared are transferable.
