Abstract: The present disclosure relates to a generalized method for producing a vertically oriented block copolymer film, a block copolymer film with controlled orientation obtained thereby, and a method for producing a self-assembled pattern. According to the present disclosure, it is possible to form a crosslinked layer, which is mechanically stable and undergoes no chemical change, by subjecting the block copolymer surface to plasma treatment using a filter. It is also possible to obtain a vertically oriented block copolymer film by annealing the block copolymer film having such a crosslinked layer. The method for producing a vertically oriented block copolymer film according to the present disclosure is advantageous in that it can be applied for general purpose regardless of the chemical structure, type and morphology of a block copolymer, and the method can be applied generally to the conventional directed self assembly process.

Abstract: A resistance-switchable material containing: an insulating support; and a complementary resistance switchable filler dispersed in the insulating support, wherein the complementary resistance switchable filler has a core-shell structure containing: a wire-type conductive core containing a conductive material; and an insulating shell formed on the surface of the core and containing an insulating material. Because a first resistive layer, a conductive layer and a second resistive layer are formed as one layer and bipolar conductive filaments are formed on the substantially different resistive layers, the memory can exhibit complementary resistive switching characteristics. In addition, the complementary resistance switchable memory of the present disclosure can be prepared through a simplified process at low cost by introducing a simple process of coating a paste in which a complementary resistance switchable filler and a supporting material are mixed.

Abstract: Disclosed are methods for preparing a resistive random-access memory (ReRAM) based on resistive switching using a resistance-switchable conductive filler. When a resistance-switchable conductive filler prepared by coating a conductive filler with a material whose resistance is changeable is mixed with a dielectric material, the dielectric material is given the resistive switching characteristics without losing its inherent properties. Therefore, various resistance-switchable materials having various properties can be prepared by mixing the resistance-switchable conductive filler with different dielectric materials. The resulting resistance-switchable material shows resistive switching characteristics comparable to those of the existing metal oxide film-based resistance-switchable materials. Accordingly, a ReRAM device having the inherent properties of a dielectric material can be prepared using the resistance-switchable conductive filler.
Abstract translation: 公开了基于使用电阻切换导电填料的电阻式开关来制备电阻随机存取存储器（ReRAM）的方法。 当通过用电阻可变的材料涂覆导电填料制备的电阻可切换导电填料与电介质材料混合时，电介质材料被赋予电阻开关特性而不失去其固有特性。 因此，可以通过将电阻可切换导电填料与不同介电材料混合来制备具有各种性能的各种电阻切换材料。 所得到的电阻切换材料显示出与现有的基于金属氧化物膜的电阻切换材料相当的电阻开关特性。 因此，可以使用电阻可切换导电填料制备具有介电材料固有性质的ReRAM器件。

Abstract: The present disclosure relates to a stretchable electrode, a method for preparing the same and a stretchable battery including the stretchable electrode. The stretchable electrode of the present disclosure, which is prepared by crosslinking a hydroxyl-functionalized fluorine-based polymer binder physically using a ketone-based solvent or chemically with a crosslinking agent, has superior stretchability, has improved interfacial adhesivity to an active material through Fenton's oxidation, exhibits improved stability under various mechanical deformations of the electrode such as stretching, etc. and can uniformly maintain the electrical conductivity, battery capacity and charge-discharge performance of the electrode.
In addition, the stretchable battery of the present disclosure, which includes the stretchable electrode, a stretchable current collector, a stretchable separator and a stretchable encapsulant, has improved stretchability and superior battery stability under various deformations due to high degree of freedom of structures and materials. In addition, the stretchable battery of the present disclosure can be prepared as a fiber battery by printing an electrode and a current collector sequentially on both sides of a stretchable fabric, which can be worn, e.g., around sleeves due to superior stretchability and high structural degree of freedom and retains high battery performance and mechanical stability even under mechanical deformation. Therefore, it can be applied to a mobile display for a health monitoring system or a smartwatch.-

Abstract: A conductive polymer composite for adhesion to a flexible substrate contains a polymer adhesive containing a curable polymer and a curing agent; and a conductive filler containing a metal and a carbonaceous material dispersed in the polymer adhesive. The conductive polymer composite is suitable for application to not only the human body but also other objects having irregular surface. In addition, due to enhanced adhesive strength of the conductive polymer composite to the flexible substrate, the reduction in conductivity or conductivity breakdown caused by external stress can be prevented and flexibility and stretchability can be improved.
