Data set on stability comparison of emulsions stabilized by cationic fluorosurfactant against conventional surfactants and high thermal performance of fluoropolymer foams.

ABSTRACT: This data article includes emulsion stability comparison of cationic fluorosurfactant (CFS) against conventional surfactants. Span 80, Hypermer, Tween 80 and CTAB were used as conventional emulsifiers and only after 30 minutes bilayer phase separation observed in emulsions prepared by Tween 80 while CTAB failed to give fluoroemulsion, as compared to the CFS stabilized fluoro-HIPE which demonstrated superb stabilization of more than 72 h without phase separation. Thermal stability of Poly(hexafluorobutyl acrylate)-Divinyl benzene (PHFBA-DVB) was compared with porous polymer prepared by the same concentration of CFS 9 wt% by using trifluoroethyl methacrylate (TFEMA) as monomer phase. Results of PFP prepared with HFBA showed remarkable stability performance at more than 340.69 °C while porous polymer synthesized by TFEMA started to decompose even at 237.36 °C. The main findings based on the data presented here are reported in the paper "A cationicfluorosurfactant for fabrication of high-performance fluoropolymer foams with controllable morphology" (Azhar et al., 2017) [1].

Project description:The aggregation behavior of two cationic surfactants, i.e., cetyldimethylethanolammonium bromide (CDMEAB) and cetyltributylphosphonium bromide (CTBPB), within an aqueous deep eutectic solvent (DES) is studied. The synthesized DES is composed of 1:2 mole ratio of choline chloride and glycerol and is further characterized by Fourier transform infrared (FTIR) and 1H NMR spectroscopy techniques. The critical micellar concentration (CMC), micellar size, and intermolecular interaction in surfactants within Gly-based DES solutions are investigated by various techniques including surface tension, conductivity, fluorescence, dynamic light scattering (DLS), FTIR, 1H NMR, and two-dimensional (2D) nuclear Overhauser effect spectroscopy (NOESY). The various interfacial properties and thermodynamic parameters are determined in the presence of 5 wt % glyceline (Gly)-based DES in an aqueous solution. The CMC, aggregation number (N agg), and Stern-Volmer constant (K sv) have also been determined by a steady-state fluorescence method. DLS is used to obtain information regarding the size of the aggregates formed by the cationic surfactants in DES solutions. FTIR spectroscopy is used to study the surfactant-DES interactions that tune the micellar structure of the surfactants within the Gly-based DES solution. The functional groups involved in the interactions (H-bonding and electrostatic) are the head groups (HO-CH2-CH2-N+ ion for CDMEAB and quaternary phosphonium (P+) ion for CTBPB) of the surfactants with the -OH-containing Gly DES. The hydrophobic moieties are involved in the hydrophobic interactions. The 1H NMR data show that differences in chemical shifts can provide significant information about the interactions taking place within the system. 1H NMR and NOESY techniques are further employed to strengthen our claim on the feasible structural arrangements within the aqueous surfactant-DES self-assembled structures. It is observed that both the cationic surfactants, i.e., CDMEAB and CTBPB, form self-assembled nanostructures in the Gly-based DES solutions. The present results are expected to be useful for colloidal solutions of DES and their mixtures with water.
