Disclosed is a method for manufacturing a functionalized separator having a zwitterionic coating thereon. The method includes preparing a porous separator; coating a linker on a surface of the porous separator; and chemically reacting zwitterions with the linker such the zwitterions are grafted to the linker on the surface of the separator. The zwitterions grafted to the linker acts as a monolayer to functionalize the surface of the separator. The functionalized separator may disallow elution of polysulfide compound in a lithium-sulfur battery. Further, the functionalized separator may increase ion conductivity of electrolyte of the lithium-sulfur battery and thus ensure high output characteristics.

The invention is directed toward systems and methods for the formation of two dimensional monolayer structures of ordered biomacromolecules, such as viruses, atop cohesive polyelectrolyte multilayers to create functional thin films. Methods for the formation of such thin films are disclosed that involve an interdiffusion-induced assembly process of the biomacromolecules. The inventive systems provide a general platform for the systematic incorporation and assembly of organic, biological and inorganic materials and will enable many potential technological applications such as, for example, chemical and biological sensors, power devices and catalytic membranes.

A hybrid porous structure may include a base template and an ionic polymer coating layer within the base template. The structural framework of the base template itself is non-porous. The base template fills the gaps among a plurality of imaginary spherical bodies stacked in three-dimensions as an imaginary stack. The ionic polymer coating layer is laminated on an inner surface of the base template inside the imaginary spherical bodies. The imaginary spherical bodies may have a pore in the center which is not occupied by the ionic polymer coating layer. The hybrid porous structure may include a plurality of necks, which are openings formed in a contact part where adjacent imaginary spherical bodies contact each other. The necks may be interconnected to the pores located in the center part of the imaginary spherical bodies.

A mask pattern is formed on a substrate by using a solvent absorbent mold having a pattern structure with a relief and an intaglio portion. A mask layer dissolved in a solvent to obtain fluidity is prepared on the substrate. The mold is pressed onto the mask layer with a predetermined pressure, and a portion of the mask layer that contacts with the relief portion of the mold is introduced into the intaglio portion thereof. Then, the mold absorbs the solvent contained in the mask layer to thereby solidify the mask layer. Next, the mold is separated from the substrate and the portion of the mask layer that contacts with the relief portion of the mold is removed, thus finally obtaining the desired minute mask pattern.
