Highly porous and chemical resistive P(TFEMA–DVB) monolith with tunable morphology for rapid oil/water separation

Abstract

A facile preparation for a series of porous poly(2,2,2-trifluoroethylmethacrylate–divinylbenzene) P(TFEMA–DVB) foams is discussed in this paper.

Methyl Methacrylate HIPE Solely Stabilized by Fluorinated Di‐block Copolymer for Fabrication of Highly Porous and Interconnected Polymer Monoliths

“…The selection of a suitable surfactant to enhance the thermodynamic stability of HIPEs is of vital importance. It is worth noticeable that only a limited number of commercially available surfactants are able to give obtrusive stability to HIPEs . The stabilization of a particular emulsion system demands a thoughtful selection of surfactant to obtain the required hydrophilic‐lipophilic balance (HLB).…”

“…It is worth noticeable that only a limitedn umber of commercially available surfactants are able to give obtrusive stability to HIPEs. [46] Thestabilization of ap articulare mulsion system demands at houghtful selection of surfactantt oo btain the required hydrophilic-lipophilic balance (HLB).F irst of all, it was tried to prepare MMA HIPEs by carefully selecting various commercial surfactants.S PAN60, CTAB, SPAN80, SPAN85, HypermerB 246a nd Tween 80 were employedt oc heck their potentiali ns tabilization of MMA HIPEs through free radicalp olymerization.

A facile fabrication of porous fluoro-polymer with excellent mechanical properties based on high internal phase emulsion templating using PLA as co-stabilizer

“…The preparation of stable uorinated emulsions is particularly difficult due to the limitations associated with available surfactants. 1,18,19 A series of surfactants were carefully selected to stabilize water/oil (w/o) emulsions using uorinated acrylate as a continuous phase monomer. HIPEs were then prepared using these conventional surfactants, i.e.…”

“…Inspection of the morphology of the porous materials post emulsion polymerization, showed that the average pore sizes of polyHIPE prepared with PLA were smaller than those produced without PLA, consistent with the observed (small) emulsion droplets sizes. The porous material prepared without PLA had the large pore structure of a conventional polyHIPE, 1,10,39 and the average pore diameter was 45.24 mm (Fig. 3A).…”

“…Hypermer-B246, rather than traditional surfactants, such as CTAB (cationic surfactant), Tween-80, Span 60, to stabilize the uorinated emulsions. 1,18 We also synthesized a cationic uorosurfactant diblock copolymer (PDMAEMA-b-PHFBA) to prepare stable high performance uoropolymer foams. 19 Similarly, we prepared and used humic acid modied iron oxide nanoparticles as a co-stabilizer to enhance the stability of uoroHIPE.…”
