Versatility of the Preparation Method for Macroporous Cryogel Particles Utilizing the Inverse Leidenfrost Effect

“…Furthermore, it is known that the porous polymer particles possess some superior physical properties, for instance, durability, stretchability, and elasticity. − In addition, the porous polymer particles could also be utilized for the immobilization of self-assemblies, which usually exist as a “dispersed” state in water, such as liposomes/vesicles, , colloids, and supermolecules, resulting in the utilization of the specific functions of their self-assemblies in a separation process design. From another point of view, the macro-/micro-porous polymer particles are expected to be applied as functional supports for various kinds of separation by modifying their surface by active and functional molecules . In general, an emulsion polymerization method is commonly adopted for the preparation strategy of porous polymer particles .…”

“…From another point of view, the macro-/micro-porous polymer particles are expected to be applied as functional supports for various kinds of separation by modifying their surface by active and functional molecules. 13 In general, an emulsion polymerization method is commonly adopted for the preparation strategy of porous polymer particles. 14 In general, during the polymerization process, detergents were required for the stabilization of emulsion in order to use them as a mold of the particle shape; the detergent molecules were adsorbed at the interface between the continuous phase and dispersed phase, and the emulsion therefore exists stably in the bulk phase during the polymerization process.…”

Micro Sponge Balls: Preparation and Characterization of Sponge-like Cryogel Particles of Poly(2-hydroxyethyl methacrylate) via the Inverse Leidenfrost Effect

“…In general, porous materials are known to exhibit high porosities and large specific surface areas. , Porous structures are usually classified as follows: (a) super-macropores are up to 100 μm in diameter; (b) macropores are larger than 50 nm in diameter; (c) mesopores are in the range of 2–50 nm in diameter; and (d) micropores are smaller than 2 nm in diameter, where the pore size is engineered according to the application. Porous materials can be applied for the preparation of various functional polymers, such as scaffolds, ,− catalyst carriers, and separation and reaction media. − Although several techniques have been devised to control the porosity of polymer materials, the most commonly employed one relies on the use of porogens during polymerization, that serve as a template for the evolution of the porous region . Examples of commonly used porogens are micelles, organic solvents, organic metals, and ice crystals .…”
