“…High internal phase emulsions (HIPEs) are extremely concentrated emulsions with >75% (v/v) internal phase . A hydrophobic internal phase may be used to stabilize water-immiscible cargo, providing an ideal platform for loading large amounts of hydrophobic cargo for drug delivery applications. , Alternatively, this strategy is also useful for preparing microporous materials via selective polymerization of the external phase and extraction of the internal phase, resulting in polyHIPEs. − The hierarchical structure of polyHIPEs has shown great potential in diverse applications such as wound dressing, tissue engineering, energy storage, , sensing, and decontamination of chemical warfare agents . Moreover, the ability to encapsulate hydrophobic molecules makes polyHIPEs ideal materials for constructing drug-eluting devices, such as drug delivery patches and implants …”
