Abstract
Cationic surfactant is an important class of surfactants,which have attracted great interest.Their properties and adsorption behavior onto different surfaces have driven the development of many surfactants with distinctive functions.Herein,the properties,the self-assembly,and the intermolecular interactions of cationic surfactants have been reviewed,as well as their interactions with small molecules or macromolecules,and surfaces.The properties of cationic surfactants of different types,including single-and double-chain cationic surfactants,and gemini,catanionic,bolaform,amino acid-and sugar-based surfactants,are summarized,as well as their skin toxicity and environmental influences.The effects of cationic surfactant mixing with other surfactants,polymers,proteins,and DNA are presented.The conventional applications of cationic surfactants as disinfectants,in fabric softening,hard surface cleaning,personal care,road surfacing,and oil field applications are outlined.Some emerging applications such as soft antimicrobial agents and nucleic acid delivery,which has contributed to the surfactant-based mRNA COVID-19 vaccines,are also introduced.关键词
