Polymerizable semi-fluorinated gemini surfactants designed for antimicrobial materials

Strategies for synthesizing non-bioaccumulable alternatives to PFOA and PFOS

“…Besides, fluorinated surfactants usually have high thermal and chemical stability [1][2][3]. They are usually composed of a perfluorinated chain and a hydrophilic group [4][5][6]. The most known fluorinated surfactants are PFOA (C 7 F 15 CO 2 H), APFO (ammonium perfluorooctanoate) and PFOS (C 8 F 17 SO 3 X, with X = K, Na, H).…”

Highly fluorinated amphiphilic molecules and self-assemblies with biomedical potential

“…Semi-fluorinated gemini surfactants with quaternary ammonium polar heads and an acrylic polymerizable function have also been synthesized and tested for their antimicrobial and antifungal activity [22]. In both cases, an amide connector between the (F-alkyl)ethyl chains and the ammonium groups led to the highest biocidal activity.…”

Surface-active properties of nitrogen heterocyclic and dialkylamino derivates of hexadecylphosphocholine and cetyltrimethylammonium bromide

“…Hydrophilic groups are connected with spacers. The most studied gemini QUATs have two hydrophobic chains, two cationic groups connected with rigid or flexible spacers [4][5][6][7]. In contrast, zwitterionic surfactants contain both positively and negatively charged hydrophilic head groups in molecules.…”
