Switchable Materials Containing Polyzwitterion Moieties

Abstract

Abstract:In recent decades, the design and construction of smart materials capable of switching into a polyzwitterionic state by an external trigger have been intensively pursued. Polyzwitterionic states have unique antifouling and surface properties and external triggers, such as pH, light, ions, electric field and CO 2 , cause significant changes in materials with regard to overall charge, ionic strength and wettability. This survey highlights current progress in the irreversible as well as the reversible switching process involving polyzwitterionic moieties, which can, in turn, be applied to studying the interaction of various interfaces with biological species as protein, DNA, bacteria or platelets and also for advanced use.

Responsive and Synergistic Antibacterial Coatings: Fighting against Bacteria in a Smart and Effective Way

“…One typical example of smart antibacterial coatings is based on zwitterionic compound/polymer derivatives, whose chemical structures could change from cationic form with bacteria‐killing ability to zwitterionic form with bacteria‐repelling ability . Jiang and coworkers designed a zwitterionic derivative monomer with a cationic ester group for surface modification via surface‐initiated polymerization (SIP) .…”

Hydrophobic and Anti-Fouling Performance of Surface on Parabolic Morphology

“…Interest in super-hydrophobic surfaces has increased in recent years [2][3][4][5][6]. Hydrophobicity and stain resistance are widely used in many areas such as anti-biofouling surfaces in a marine environment [7][8][9][10], fluid drag reduction [11,12], anti-contamination surfaces of windows for buildings and automobiles [13][14][15], microfluid [16,17], and many others. Therefore, studying hydrophobicity and stain resistance is particularly important in industry, agriculture, and people's daily life.…”

Photochemical grafting of polysulfobetaine onto polyethylene and polystyrene surfaces and investigation of long‐term stability of the polysulfobetaine layer in seawater

“…Zwitterionic‐based coatings increase interest for biomimetic, unique charged balanced characteristic and has come to be new benchmark for antifouling materials . Zwitterionic materials were applied as materials with extremely good blood compatibility, with inhibition of adsorption of protein and adhesion of cells and for bioconjugation, protection against bacteria, biosensor surface, immobilization matrix for protein, and other advanced and smart applications . Such modification also prevents marine settlement as was demonstrated by sulfobetaine and carboxybetaine methacrylate polymer brushes that were applied for inhibition of adhesion and settlement for cypris larva of barnacle Balanus Amphitrite .…”

“…14 Zwitterionic materials were applied as materials with extremely good blood compatibility, 15,16 with inhibition of adsorption of protein and adhesion of cells 17,18 and for bioconjugation, [19][20][21] protection against bacteria, 22,23 biosensor surface, 24,25 immobilization matrix for protein, 26 and other advanced and smart applications. 27 Such modification also prevents marine settlement as was demonstrated by sulfobetaine and carboxybetaine methacrylate polymer brushes that were applied for inhibition of adhesion and settlement for cypris larva of barnacle Balanus Amphitrite. 28,29 Furthermore, grafted sulfobetaine polymer on glass revealed that only few spores of green marine alga, Ulva, settled (attached) on the poly(sulfobetaine methacrylate) surfaces, and the adhesion strength of both spores and sporelings (young plants) was low.…”
