Swellable functional hypercrosslinked polymer networks for the uptake of chemical warfare agents

“…34 Similarly, modification of HCPs with imidazolium ionic liquids helped to increase polarity for enhanced adsorption of catechin from herbal plants. 35 The propensity of HCPs to swell has led their use in a number of applications including the trapping of organic vapors, 36 ion exchange, 37,38 removal of toxic trace metals, 39,40 solid phase extraction, 41 and recovery of organic compounds from water. 42,43 Knitting of the triptycene monomer can produce HCPs which show high adsorption for solvents including DMSO, toluene, and ethyl acetate, with a 30 times increase in the mass of the polymer observed for adsorption of chloroform.…”

High surface area polyHIPEs with hierarchical pore system

“…3 Applications of hypercrosslinked polymers of the Davankov-type include the separation of organic compounds from the gaseous 4 or liquid phase, 5 reversed-phase HPLC chromatography 6 and ion exchange resins. 7 The BET surface area of these polymeric materials can amount up to 2000 m 2 g À1 , 8 thus, their use as a storage material for hydrogen has been studied in the past. 9,10 A maximum storage capacity of 3.04 wt% at 15 bar was then reported.…”

Rapid Generation and Control of Microporosity, Bimodal Pore Size Distribution, and Surface Area in Davankov-Type Hyper-Cross-Linked Resins

“…Moreover, the resins swell to similar degrees in both good and poor solvents for polystyrene, in keeping with the argument that all solvents should return each dried network to its lowest energy state formed under the conditions of hyper-cross-linking . These properties provide potential for applications as improved sorbents for organic vapors, for recovery of organic compounds from water, − for toxic trace metal removal, , as ion-exchange resins, , and in preconcentration of hydrophilic aromatic compounds by reversed-phase HPLC . Indeed, such materials are now available from a number of commercial sources .…”
