Abstract: Provided is a flexible thin-film transistor using a two-dimensional semiconductor material, which includes: a flexible substrate; a channel formed on the flexible substrate and formed of a two-dimensional semiconductor material; a gate insulator and a gate electrode stacked sequentially on the channel; and source and drain electrodes formed on the channel as being spaced apart from the gate electrode.

Abstract: Provided are a micro-porous hybrid film and a method for preparing the same, and more particularly, a micro-porous hybrid film capable of improving reliability of a battery by simultaneously improving thermal stability at a high temperature and water properties, and a method for preparing the same. In addition, the present invention relates to a micro-porous hybrid film suitable for a separator of a high capacity/high output lithium secondary battery capable of increasing production stability, long term stability, and performance of the battery by improving adhesive force between a micro-porous film and a coating layer and permeability and minimizing a water content by the coating layer.

Abstract: The following disclosure relates to a microporous polyolefin composite film having excellent heat resistance and thermal stability, and a method for manufacturing the same. More particularly, the present invention relates to a microporous polyolefin composite film capable of improving stability and reliability of a battery by heat sealing an edge of a microporous film provided with a coating layer that includes a polymer binder and inorganic particles, and a method for manufacturing the same.

Abstract: Provided is a micro-porous polyolefin composite film, the micro-porous polyolefin composite film including a porous coating layer containing a polymer binder and inorganic particles, the polymer binder simultaneously employing an aqueous polymer and a non-aqueous polymer. The contents of the aqueous polymer and the non-aqueous polymer are controlled, and thus optimize heat resistance, adhesive strength, and the moisture content to thereby improve high-temperature stability, and, further, improve the adhesive strength to thereby improve stability in production, and minimize the moisture content to thereby improve reliability of a battery.
