New ampholyte biomaterial compounds containing ampholyte moieties are synthesized and integrated into polymeric assemblies to provide hydrophilic polymers exhibiting improved biocompatibility, haemocompatibility, hydrophilicity non-thrombogenicity, anti-bacterial ability, and mechanical strength, as well as suitability as a drug delivery platform.

The present invention provides a reactive fluorosurfactant, and a preparation method therefor and a use thereof. The reactive fluorosurfactant is a polymer of which a main chain contains the following structural units: (A), (B), and (C). The reactive fluorosurfactant provided in the present invention has a good effect of reducing the surface tension of an aqueous phase system, and can be used in an aqueous emulsion polymerization method to prepare a fluoropolymer; moreover, the reactive fluorosurfactant participates in a polymerization reaction, and a fluoropolymer emulsion prepared by using the reactive fluorosurfactant is stable and has no phenomenon of emulsion breaking.
