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: 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.
