Hyperbranched Polymeric Fluorosurfactants: Synthesis, Surface Activity and Their Application in Firefighting Foams
Hyperbranched polymeric fluorosurfactants had a strong synergism with the small molecule fluorosurfactant C1157 in raising their surface activity
which favored their use for highly efficient fire-extinguishing towards flammable oils.
Abstract
Fluorosurfactants are the key ingredients in the formulations of aqueous film-forming foams (AFFFs) for extinguishing flammable liquids
thus developing high-efficient and low-toxic fluorosurfactants is desirable in AFFFs application. Herein
a series of hyperbranched polymeric fluorosurfactants (HPFs) were successfully synthesized through sequentially modifying hyperbranched polyethylenimine (PEI) with the hydrophilic poly(ethylene glycol) (PEG) chains and the hydrophobic C6/C4-based perfluoroalkyl chains
which were verified by FTIR
1
H- and
19
F-NMR. The surface tensions of all the HPFs in water were measured
and the corresponding physicochemical parameters were interpreted. It was found that the surface activities of HPFs could be tuned through adjusting the ratio of PEG to perfluoroalkyl chains
the length of perfluoroalkyl chains
the molecular weight of PEI core
but not the PEG chain length. In the binary mixture of HPFs with the commercial small molecule fluorosurfactant Capstone
TM
1157 (C1157)
a strong synergism led to the elevation of surface activity
which was attributed to the efficient encapsulation of C1157 guests by the compact hyperbranched HPFs as the hosts. The utilization of HPF/C1157 as fluorosurfactant ingredients in AFFF formulations could realize much higher fire-extinguishing efficiency towards flammable oils than the control AFFFs prepared from the polymeric Capstone
TM
1460 or the neat C1157.
