    Abstract: A heat-dissipating plastic is provided. The heat-dissipating plastic according to an exemplary embodiment of the present invention is implemented by including a polymer matrix formed by including a main resin; and a carbon-based filler which is provided by being dispersed in the polymer matrix, and includes a fibrous carbon-based filler and a granular carbon-based filler.
    According to the above, the heat-dissipating plastic has remarkably excellent heat dissipation characteristics due to the remarkably excellent thermal conductivity, and it has an effect that the mechanical strength is remarkably excellent even though it is designed to have remarkably excellent heat dissipation characteristics. Accordingly, the implemented heat-dissipating plastic can be widely applied in various technical fields where excellent heat-dissipating performance and mechanical strength are required at the same time.

    Abstract: A method for manufacturing an ion exchange membrane is provided. The method for manufacturing an ion exchange membrane, according to one embodiment of the present invention, comprises the step of electrospinning a support fiber producing solution and an ion exchange fiber producing solution respectively to prepare a laminate in which a support fiber mat consisting of a support fiber and an ion exchange fiber mat consisting of an ion exchange fiber are alternatively laminated. According to the present invention, it is possible to simply control factors, such as the thickness, electroconductivity and mechanical strength of the membrane, and the diameter/ratio of a pore, etc. to be suitable for the use of ion exchange membrane during the manufacturing process, to simplify the manufacturing process. As such, the ion exchange membrane manufactured by the method can be utilized as a universal ion exchange membrane which has a large ion exchange capacity, a small electrical resistance, and a small diffusion coefficient as well as excellent mechanical strength and durability.
