“…Therefore, it is a great challenge to improve the mechanical properties of polyHIPEs while maintaining their high porosity and interconnectivity. As a result, much efforts were dedicated to solving this issue, and several approaches, including selection of the appropriate monomers [52, 53], crosslinkers [44, 54, 55], and surfactants [48, 56], incorporation of organic/inorganic components [16–20, 28, 54–57], introduction of novel polymerization methods [6–8, 58, 59], and postcarbonization of polyHIPEs [40–42], have been developed, which make polyHIPEs fascinating candidate porous materials for a variety of applications including cell culture [33, 34], tissue engineering [60–62], energy storage [63, 64], enzyme immobilization [35, 65, 66], protein purification [67–69], separation, and enrichment [9, 23–26, 70–74].…”
