WIPO Patent Application WO/2016/003212
Kind Code:
A1
Abstract:
The present invention relates to a non-spherical amphiphilic polymer nanoparticles having interfacial properties which can be reversibly controlled by temperature at the aqueous solution-to-oil and aqueous solution-to-solid interfaces, a method for producing the non-spherical amphiphilic polymer nanoparticles, and an emulsion composition or a nanopattern-forming composition comprising same, the hydrophilic and hydrophobic properties of the particle surface of the non-spherical amphiphilic polymer nanoparticles according to the present invention reversibly changing with temperature, thus allowing the interfacial properties between liquid-to-liquid or liquid-to-solid to be reversibly controlled by temperature. Accordingly, the emulsion composition comprising the non-spherical amphiphilic polymer nanoparticles according to the present invention can maximize the delivery of drugs, cosmetics and the like in the medical and cosmetic fields by controlling the size of the emulsion by means of temperature-based control of the interfacial properties. Additionally, the effectiveness of the lithographic process for semiconductor chip production can be maximized in the electronics industry as the wettability of the liquid for a solid substrate can be controlled by using the characteristic in which the interfacial properties can be reversibly controlled by temperature. Furthermore, the present invention can be used as a printer ink composition and the like in the printer ink and paint industries to maximize the coating effectiveness on the surface of printer paper and painting surfaces having diverse surface characteristics.
