Wetting behavior of polyelectrolyte complex coacervates on solid surfaces

Abstract

The wetting behavior of complex coacervates underpins their use in many emerging applications of surface science, particularly wet adhesives and coatings. Many factors dictate if a coacervate phase will condense...

Tailoring Interactions of Random Copolymer Polyelectrolyte Complexes to Remove Nanoplastic Contaminants from Water

“…This concept was utilized to form nanoscale aggregates of oppositely charged random heteropolymers and single proteins, which have a heterogeneous surface, in organic solvents and polymer melts. , We demonstrated complexation of random copolymers and the enzyme PETase in an aqueous solution, which increased the activity of the PET-degrading enzyme on PET films. One potential mechanism for this enhancement is the ability of the copolymer-enzyme complex to stick and adsorb onto a PET surface due to a hydrophobic surface affinity between the polymer and PET surface . Here, we hypothesize that favorable interactions between macroscopic random copolymer PECs and PET can be utilized in flocculation to remove PET nanoplastics from solution.…”

Tuning of scleroglucan adsorption on carbonate surfaces via grafting alkyl side chains of different lengths: a theoretical and experimental study

“…[8][9][10][11][12][13] On the other hand, theoretical studies of the adsorption process is crucial for better controlling the mechanisms underlying the process and providing insight into the experimentally inaccessible parameter set. [14][15][16][17][18][19][20] Scheutjens and Fleer 21 proposed a general self-consistent field theory (SCFT) to investigate the adsorption of flexible homopolymers on solid surfaces. Using the SCFT, the probability of different chain conformations including loops, tails, and trains can be calculated.…”

Electrically Mediated Static Contact Angle and Hysteresis of Polyelectrolyte Solutions

“…The electrowetting behavior of PE solutions was studied by Choi et al who demonstrated the suppression of the electrowetting breakdown voltage by using a PE/surfactant mixture (poly­(acrylic acid) (PAA) and Tween80). Using complex coacervates on solid surfaces, Balzer et al investigated both off-coexistence (wetting transitions) and on-coexistence (contact angles) wetting behavior . According to their study, the salt concentration, surface affinity for polycation/polyanion, and electrostatic potential affect the wettability.…”

A study by Seńećhal et al investigated how an electric field affects PAA brushes coated on surfaces.…”
