Thus, the movable antibacterial buoyancy body can be conveniently used, regardless of the type and form of sprayers, such as the body shape and spray pattern of sprayers. Furthermore, a typical sprayer can be used without modifications. In addition, since the antibacterial buoyancy body can freely float according to the flow of the water, active components of the antibacterial buoyancy body are transferred to all regions of the water, including the central portion and peripheral portion of the water, and thus work in all regions thereof. Moreover, the antibacterial buoyancy body may be fabricated, for example, in a fish shape or a petal shape, to thereby decorate the inside of the sprayer.

The present invention improves preservation stability which might cause problems in conventional coating liquids or solutions containing silver nanoparticles, which cannot be preserved in air. Thus, the present invention can be applied in a wider range of fields and also in a field requiring long-term preservation. Furthermore, the present invention has a superior bonding stability and oxidation resistance at a temperature higher than 700°C which is the melting point of silver, and thus can be applied to products requiring high-temperature resistance, namely, ceramics, special films, fibers, etc. The silver nanoparticles of the present invention have superior antibiotic properties and EMI-shielding properties, which improve the applicability to a microwave oven or the like, which conventional products may not have.

METHOD FOR SYNTHESIZING ONE-DIMENSIONAL HELICAL NANOPOROUS STRUCTURES AND METHOD FOR SYNTHESIZING GLYCINE-DERIVED SURFACTANT FOR SYNTHESIZING HELICAL NANOPOROUS STRUCTURES
Disclosed herein are a method for synthesizing one-dimensional helical mesoporous structure, in which a self-assembled structure of a glycine-derived surfactant is used as a template at room temperature to synthesize the one-dimensional helical mesoporous silica structures having a uniform pore size and a method for synthesizing a glycine-derived surfactant for synthesizing the helical nanoporous structures, in which relatively expensive surfactant can be easily recovered using an organic solvent and reused, which provides economical and environment friendly effects and the glycine-derived surfactant is synthesized by homogeneously heating a reaction product of glycine and phthalic anhydride by dielectric heating with irradiation of microwave, whereby it is possible to realize high yield of the glycine-derived surfactant, shortened synthesis time and increase in energy efficiency, leading to improvement in productivity and reduction in production cost.
