  • Are zwitterionic polymers ionic or cationic?
  • This review is focused on the structure and synthesis of zwitterionic polymers. Polyzwitterions or synonymous polybetaines bear, within their constitutional repeat unit, the same number of anionic and cationic groups . Essentially, the ionic groups are functional over a large pH-window.
  • Are zwitterionic polymers a problem?
  • With the continuous expansion of applications, problems with zwitterionic polymers have been exposed. The current structure of zwitterionic polymers cannot meet the requirements for further development, and more zwitterionic polymers with new-type ideal structures need to be synthesized.
  • How can zwitterionic polymers be synthesized?
  • Zwitterionic polymers can be synthesized by copying monomers containing cationic and anionic functional groups, as shown in Table 1 [5, 24]. The initial synthesis of polymerizable betaine monomers, followed by copolymerization with other functional monomers is an achievable approach [54, 58].
  • Are zwitterionic polymers resistant to nonspecific protein adsorption?
