WebMar 4, 2011 · Abstract. A series of novel zwitterionic phosphobetaine (PPBT) surfactants were synthesized using long chain fatty alcohol, epichlorohydrin, dimethylamine and sodium dihydrogen phosphate as raw materials. The physicochemical properties of the … Webbetaine hydrogels, consisting of phosphobetaine, sulfobetaine, or carboxybetaine polymers, are also of interest as a new type of hydrogels.25,26 They can be prepared through initiating a mixed solution containing a zwitterionic betaine monomer and a cross-linker. Due to their excellent biocompatibility, anti-biofouling
