High surface area polyHIPEs with hierarchical pore system

Synthesis and properties of polystyrene-based polyHIPEs reinforced with quadruple hydrogen bond functionality

“…These hierarchically porous materials, known as polyHIPEs, have huge amount of voids and windows (or throats, the small pores connecting the neighbor voids) by removal of the internal phase. PolyHIPEs have advantages such as high permeability, easy preparation, facile control of voids and windows size, etc., which are being considered for myriad applications such as in filtration media for separation [4][5][6][7][8], support for catalyst [9][10][11], scaffold for tissue engineering [12][13][14][15][16][17][18], adsorbent for scavenging [19][20][21][22][23][24][25][26] and storage for hydrogen [27,28].…”

Highly permeable macroporous polymers via controlled agitation of emulsion templates

“…This allows for the production of macroporous polymers with desirable properties such as permeability [7,22], surface area [5,23] and mechanical strength [24] that can be tailored for desired tasks. Much work has been done on predicting the droplet size of emulsions produced in agitated vessels [25][26][27][28], it is therefore suggested that the morphology of emulsion templated macroporous polymers can be predicted in a similar fashion.…”

Robust macroporous polymers: Using polyurethane diacrylate as property defining crosslinker

“…This method was first reported by Bartl and von Bonin [2], and has been further developed over the past 5.5 decades. By tailoring the formulation of emulsion templates, the properties of the resulting macroporous polymers, such as porosity, pore size, pore interconnectivity and, therefore, permeability, surface area, and morphology of the polyHIPEs can be tailored to suit various applications in/as membrane and separation technologies [3e7], hydrogen storage [8], catalyst supports [9], electrodes for microbatteries [10], oil servicing [11], as low dielectric substrates for use in the electronics industry [12] and scaffolds for tissue engineering [13,14].…”
