Abstract:
PURPOSE: A composite complex separator is provided to have excellent strength and durability and to improve surface hydrophilicity while maintaining original strength when introducing a hydrophilic functional group. CONSTITUTION: A composite complex separator comprises a support layer which comprises a fluorine-based polymer, and an active layer which comprises polyamide formed on the surface of the support layer. The support layer has a nanofiber web. The fluorine-based polymer is a fluorine-based polymer which is selected from polyvinyl fluoride, polyvinylidene fluoride, polytetra fluoro ethylene, polychlorotrifluoroethylene, fluorinated ethylene-propylene, perfluoroalkoxy polymer, and perfluoro polyoxetane; a copolymer including 50% or more a repeating unit which form the fluorine-based polymer, based on the number of repeating units in a polymer chain; and a polymer blend mixed with 50weight% or more of the fluorine-based polymer.

PURPOSE: An arm curl exercise device is provided to develop various muscles by moving upper arms while maintaining the development of biceps. CONSTITUTION: An arm curl exercise device comprises: a fore arm guide member(110) which is expanded in one direction and is formed of a handle in one side thereof; an upper arm guide member(111) which is combined with the other end of the fore arm guide member and rotates upward by the motion of upper arm; an upper arm supporting pad(103) which moves upward together with the upper arm guide member when the upper arm guide member rotates upward; and a stop guide(102) which stops the operation of the fore arm guide.
