Crosslinked-gel microcapsules immobilized small droplets of phenolic oxime extractant, 1-(2-hydroxy-5-nonylphenyl) ethanone oxime (LIX84-I) were prepared from O/W emulsion using falling-drop method followed by crosslinking of sodium alginate (Na-Alg) by Ca2+ ion and crosslinking of polyvinyl alcohol (PVA) by glutaraldehyde. A lot of fine droplets of LIX84-I were successfully immobilized in the microcapsules. The LIX84-I contents in the microcapsules increased with an increase in the LIX84-I amounts to the aqueous phase. The maximum extracted amounts of Cu(II) increased linearly with the LIX84-I contents with a slope of 1/2 which means two molecules of LIX84-I react with one Cu(II) ion. The extraction rate was not significantly affected by the size of the extractant droplets dispersed in the microcapsules. The microcapsules could be used repeatedly for the extraction and back-extraction of Cu(II).

In order to apply microcapsules as a functional material of cement composites, such as self-healing and heat-transfer-controlling materials, the effect of the addition of microcapsules on the mechanical properties of cement mortar was investigated. Polystyrene microcapsules containing CaCl2 aqueous solution as a microencapsulation substance with monocore and multicore structures were successfully prepared from solid-in-oil-in-water (S/O/W) emulsion by the solvent evaporation method. The compressive strengths of the mortars with and without the microcapsules were measured at various curing times. The compressive strength of the mortar without microcapsules increased with curing time. The compressive strength of the mortar with the microcapsules was lower than that without microcapsules and increased with time. The decrease in the compressive strength increased with the amount of the microcapsules added in the mortar. The self-healing effect of cracked mortar by CaCl2, which would be supplied from the microcapsules due to outer mechanical force making cracks in the mortar and on the microcapsules was not clearly shown in this experiment. However, permeation and leakage of Cl- ion to the surrounding mortar from the microcapsules was observed by mapping analysis of SEM-EDX.

Here, we prepared hydrophobic cryogel particles with monolithic supermacropores based on poly-trimethylolpropane trimethacrylate (pTrim) by combining the inverse Leidenfrost effect and cryo-polymerization technique. The hydrophobic cryogel particles prepared by adopting this method demonstrated the separation of the stabilized O/W emulsion with surfactant. The prepared cryogel particles were characterized in terms of macroscopic shape and porous structure. It was found that the cryogel particles had a narrow size distribution and a monolithic supermacroporous structure. The hydrophobicity of the cryogel particles was confirmed by placing aqueous and organic droplets on the particles. Where the organic droplet was immediately adsorbed into the particles, the aqueous droplet remained on the surface of the particle due to repelling force. In addition, after it adsorbed the organic droplet the particle was observed, and the organic solvent was diffused into the entire particle. It was indicated that monolithic pores were distributed from the surface to the interior. Regarding the application of the hydrophobic cryogel particles, we demonstrated the separation of a stabilized oil-in-water emulsion, resulting in the successful removal of the organic solvent from the emulsion.

Here, we report a method to prepare cryogel particles with sponge-like mechanical properties, including high porosity and high elasticity. The preparation process of the cryogel particles of poly(2-hydroxythyl methacrylate) can be summarized in the two following steps: preparation of frozen droplets using the inverse Leidenfrost effect, followed by cryo-gelation by frozen polymerization. First, a polymer precursor was dropwise added into bulk liquid nitrogen (-196 °C). Then, frozen droplets were created by the inverse Leidenfrost effect, which were subsequently polymerized in liquid paraffine (-15 °C). After thawing and drying, the cryogel particles were obtained. The monolithic super-macroporous structure was observed by scanning electron microscopy (SEM). The mechanical properties of the cryogel particles were studied via compression-swelling tests. At maximum compression, the particles achieved 94.3% degree of deformation; remarkably, they returned to their original shape under the swelling state. The strategy proposed herein, which combines the inverse Leidenfrost effect with a cryo-polymerization technique, could be applied to prepare various polymer particles without employing surfactants.

Chiral selective adsorption of L-amino acid, tryptophan (Trp) was achieved using phospholipid membrane-coated porous polymer particles (PPPs). PPPs with numerous pores were prepared by in situ polymerization of divinylbenzene, and then coated with 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC, L-phospholipid) via the impregnation method. Elemental mapping of energy dispersive X-ray (EDX) analysis revealed that DPPC molecules were distributed to the surface and the inner part of PPPs, where almost all the DPPC molecules applied for impregnation were deposited on PPPs. The phospholipid membrane properties of DPPC-PPPs were characterized using the fluorescence probe 6-lauroyl-2-dimethylaminonaphthalene (Laurdan). The results show that DPPC-PPPs possessed a lipid membrane-like environment similar to pure DPPC liposomes, especially at temperatures below 35 °C. DPPC-PPPs slightly adsorbed L-Trp and D-Trp at 45 °C, while DPPC-PPPs significantly adsorbed L-Trp but not D-Trp at 30 °C: enantio excess (e.e.) was 75.0%. The time course of Trp adsorption was investigated: for both enantiomers, similar adsorption behaviors were observed for 30 h, thus suggesting surface adsorption onto DPPC-PPPs. L-Trp adsorption continued after 30 h, suggesting that L-Trp could be distributed in the inner part of DPPC-PPPs. Interestingly, the reused DPPC-PPPs featured improved adsorption performance, suggesting that the deposited DPPC membranes on PPPs could act as chiral selectors for L-Trp. The optical resolution of L-/D-Trp was performed using DPPC-PPPs, resulting in the e.e. of D-Trp was > 60%. Thus, DPPC-PPPs have the potential of chiral selective adsorption of L-amino acid, which can be used as chiral separation materials.
