Abstract: The present disclosure relates to an extremely deformable structure comprising a basic displacement unit having an embedded form, in which m polygonal basic unit cells are disposed adjacent to each other, m separation parts are formed among the m basic unit cells, a junction part connecting the basic unit cells to each other is formed between the basic unit cells in which the junction part has a junction part pattern in which an external junction part disposed at the outer portion of the basic unit cell and an internal junction part which is not in contact with the outer portion of the basic unit cell are sequentially repeated, and the relative positions of the m basic unit cells are changed according to the junction part pattern, and thus, are activated (here, m is an integer of 4 or 6). Further, the present disclosure relates to a lithium secondary battery made from the extremely deformable structure.

Abstract: A method to prepare polymer woven fabric surface with selective oleophilicity or hydrophobicity and oil-oil separation and oil-water separation filter prepared by using the surface. The method to prepare the surface with selective oleophilicity or hydrophobicity includes steps comprising a step to form nano meter sized pores on the surface of the polymer woven fabric surface with micro sized pores through drying type etching; and a step to form selective oleophobic or hydrophobic film on the nano meter sized pores. It is possible to control hydrophobic/oleophobic property according to pore size, material or thickness of the film and this polymer surface with hybrid pores can be used in various areas such as an oil filter for car capable of selective separation of oil-oil mixture and water-oil mixture, disposal of waste oil, treatment of marine oil leakage, and pretreatment of crude oil refinement.

Abstract: A flexible secondary battery includes an exterior member having an accommodation space inside, a cathode collector and an anode collector located in the accommodation space and spaced apart from each other, a cathode active material portion on the cathode collector, and an anode active material portion on the anode collector. The cathode collector includes a first connection portion extending in a first direction and a plurality of first leg portions protruding from the first connection portion in a second direction different from the first direction. The anode collector includes a second connection portion parallel to the first connection portion and a plurality of second leg portions protruding from the second connection portion toward the first connection portion. The first leg portions and the second leg portions are alternately arranged between the first connection portion and the second connection portion. The cathode active material portion is located only on the first leg portions. The anode active material portion is located on the second connection portion and the second leg portions.

Abstract: Disclosed is a membrane electrode assembly with enhanced hydrophobicity and a method for manufacturing the same. In particular, a nano pattern with a high aspect ratio is formed in a catalyst support on the surface of a catalyst layer constituting the membrane electrode assembly using plasma etching. A hydrophobic thin film is then formed on the nano pattern formed in the catalyst support.
