Which zwitterionic units are used in Zp-HPAM?

The optimized zp-HPAM containing zwitterionic units and PEG units shows relatively high viscosity and good viscosity retention at 90°C in a synthetic brine of 20 × 10 4 mg/L salinity. The synergistic combination of zwitterionic units and PEG units in the zp-HPAM is considered to enhance the tolerance to high salinity and high temperature. SCHEME 1.

Can zwitterionic polymers be used as therapeutic agents?

In addition to micellar structures, conjugates of zwitterionic polymers with therapeutic agents have broad application prospects in the biomedical field. Compared with general polymers, zwitterionic polymers are more hydrophilic and can exert better protective effects and improve the solubility of drugs .

How do zwitterionic polymers adjust their charge distribution and intermolecular interactions?

Zwitterionic polymers dynamically adjust their charge distribution and intermolecular interactions in response to environmental changes such as pH and salinity variations, thereby maintaining their anti-fouling and oleophobic properties.

Are zwitterionic polymers pH-responsive?

The pH of the environment can easily affect the electrostatic interactions between zwitterionic polymers and other substances by shifting the positive and negative charges carried by the polymer chains. Therefore, zwitterionic polymers are generally pH-responsive. Zwitterionic polymers have different zeta potentials in media of different pH.

Can zwitterionic polymers be used in antifouling membranes?

Engineering strategies for incorporating zwitterionic polymers into membranes. Various applications of zwitterionic polymeric antifouling membrane were discussed.

Can zwitterionic polymers be used to remove contaminants?

In the field of industrial engineering, owing to the high charge density of zwitterionic polymers and their propensity for strong electrostatic interactions, it is possible to break the spatial disorder encountered with conventional polymers when zwitterionic polymers are used to remove contaminants.
