Abstract: Disclosed are a method of preparing liposomes using a mixed solvent of ethyl acetate and n-hexane for dissolving phospholipids, and a method of preparing a liposome frozen powder by putting a container including liposomes in a container filled with isopropyl alcohol, ethanol and/or methanol, followed by lyophilization, which methods are useful in food industry for no use of toxic chloroform. Disclosed also is adding the produced container including liposomes to a container filled with isopropyl alcohol, ethanol and/or methanol, followed by lyophilization, thus advantageously preventing deterioration in stability of liposome particles, as well as being almost completely returned to the original state.

Abstract: This invention relates to amphiphilic hydrogel particles for antifouling paint, which are environmentally friendly and in which anti-corrosion and antifouling effects can be maximized through a single coating process. The amphiphilic hydrogel particles are fabricated by encapsulating conducting polymer particles having anti-corrosion functionality with functional nanoparticles having antifouling functionality and then immobilizing the functional nanoparticles on a hydrogel matrix, whereby the conducting polymer particles contained in the functional nanoparticles are slowly and continuously released or the release rate thereof can be controlled so as to release the corresponding particles in a specific environment, ultimately maintaining long-term functionality. The conducting polymer particles contained in the amphiphilic functional nanoparticles can exhibit anti-corrosion functionality, thus maximizing anti-corrosion and antifouling effects through a single coating process.
