Abstract: The present disclosure relates to a styrene-based copolymer for an electrode binder of a solid alkaline fuel cell, represented by the following Chemical Formula 1, an electrode binder including the same, and a membrane electrode assembly including the electrode binder. The electrode binder for a solid alkaline fuel cell is obtained by dispersing the styrene-based copolymer for an electrode binder in a mixed solvent of alcohol with water. Thus, even when coating electrode catalyst slurry including the electrode binder directly on an electrolyte membrane, the electrolyte membrane is not damaged so that the quality of a solid alkaline fuel cell using the same may be improved. wherein x is an integer of 2-10, and each of m and n represents the number of repeating units.

Abstract: Provided are a method for fabricating a highly elastic porous polymer membrane, a method for manufacturing a cell culture system using a porous polymer membrane fabricated by the fabrication method, and a cell culture system manufactured by the manufacturing method. The porous polymer membrane can be fabricated by spin coating a mixture solution containing a biodegradable elastomeric polymer and a water-soluble moisture absorbent in an optimum ratio while maintaining a high relative humidity. The porous polymer membrane has a uniform thickness and a uniform pore size and is highly elastic. In addition, the thickness and pore size of the porous polymer membrane can be controlled. The porous polymer membrane can induce active cell-cell interaction during cell co-culture due to its high porosity. The porous polymer membrane enables control over cell alignment or array due to its high biocompatibility and elasticity. The porous polymer membrane can be utilized in a platform for inducing stem cell differentiation, a lab-on-a-chip, a synthetic skin simulant platform, etc.

Abstract: The present disclosure relates to 2-dimensional MXenes surface-modified with catechol derivatives, a method for preparing the same, MXene organic ink including the same, and use thereof (e.g. flexible electrodes, conducive cohesive/adhesive materials, electromagnetic wave-shielding materials, flexible heaters, sensors, energy storage devices). Particularly, the simple, fast, and scalable surface-functionalization process of MXenes using catechol derivatives (e.g. ADOPA) organic ligands significantly improves the dispersion stability in various organic solvents (including ethanol, isopropyl alcohol, acetone and acetonitrile) and produces highly concentrated organic liquid crystals of various MXenes (including Ti2CTx, Nb2CTx, V2CTx, Mo2CTx, Ti3C2Tx, Ti3CNTx, Mo2TiC2Tx, and Mo2Ti2C3Tx). Such products offer excellent electrical conductivity, improved oxidation stability, excellent coating and adhesion abilities to various hydrophobic substrates, and composite processability with hydrophobic polymers. This finding will lead to further studies on the structures, properties, and physics of the organic MXene liquid crystals and their practical applications.

Abstract: Provided are a method for producing a stereocomplex polylactic acid composite based on oil-in-water emulsion blending, a method for preparing a drug delivery composition using a stereocomplex polylactic acid composite produced by the production method, and a drug delivery composition prepared by the preparation method. The stereocomplex polylactic acid composite is produced using oil-in-water emulsion blending that has the advantages of simple process, short production time, and high stereocomplexation efficiency compared to existing methods such as solution blending, melt-blending, and supercritical fluid technology. In addition, the drug delivery composition is prepared using oil-in-water emulsion blending that allows the drug to be loaded into the polymer chains of the stereocomplex polylactic acid in a very easy and efficient manner and facilitates release of the drug at room temperature over a long period of time.
