Abstract: The present invention relates to a mesoporous film structure having ultra-large pores therein and a method of manufacturing the same. More particularly, the present invention relates to a mesoporous film structure having ultra-large pores therein and a method of manufacturing the same, in which a mesoporous film having ultra-large pores therein is formed on supports including various materials and having various shapes under chemically mild conditions. The size of the pores in the film is capable of being adjusted, and a patterned mesoporous structure is formed on the upper surface of the support rather than throughout the entire support.

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.
