    • Disclosed are frame-connecting members such as straight, straight-curved, T-shaped and cross-shaped connecting members being used when assembling or fabricating vinyl houses, etc, and method for manufacturing the same. The frame-connecting member comprises a first connecting part, having a metal pipe shape, which connects a frame of a first direction, a second connecting part, having a metal pipe shape and corresponding to the first connecting part, which connects a frame of a second direction, and a fixed part, placed between the first connecting part and the second connecting part and molded with the molding material of a synthetic resin, which connects the connecting parts. A method for manufacturing a frame-connecting member comprises the steps of (a) forming a hole, (b) disposing an upper molding frame and a lower molding frame, (c) introducing a molding material into the fixed part, (d) releasing the upper and lower molding frames from the fixed part, (e) forming a connecting groove, and (f) inserting rods into the opposedly-placed first and second connecting parts. The frame-connecting member according to the present invention provides a straight connecting member having two-way connecting holes into which common pipe frames are inserted, a straight-curved connecting member for a curved two-way connected section, a three-way connecting member for a three-way connected section, and a four-way connecting member for a four-way connected section, respectively.

    • The present invention relates to an ionic liquid-polymer gel membrane with improved gas permeability, and a preparation method thereof, and more specifically, to a membrane prepared to allow an ionic liquid to be dispersed in a polymer gel, thereby improving gas permeability. Particularly, the present invention relates to an ionic liquid-polymer gel membrane wherein membrane selectivity and permeability exceed an upper bound by increasing the amount of dispersed ionic liquid, and a preparation method thereof. The preparation method of the membrane for separating a specific gas from a mixture gas according to the present invention comprises the following steps of: mixing a polymer, an ionic liquid and PC as a solvent to prepare a mixture solution; and drying the mixture solution to remove the solvent from the mixture solution. In addition, the polymer is polyvinylidene fluoride-hexafluoropropyl copolymer (PVdF-HFP), and the ionic liquid is 1-ethyl-3-methylimidazolium tetrafluoroborate ([emim][BF4]).
    • 本发明涉及具有改善的气体渗透性的离子液体 - 聚合物凝胶膜及其制备方法,更具体地说,涉及一种允许离子液体分散在聚合物凝胶中的膜,从而提高透气性。 特别地,本发明涉及离子液体聚合物凝胶膜及其制备方法,其中膜选择性和渗透性通过增加分散的离子液体的量而超过上限。 根据本发明的用于从混合气体中分离特定气体的膜的制备方法包括以下步骤:将聚合物,离子液体和PC作为溶剂混合以制备混合溶液; 并干燥混合溶液以从混合溶液中除去溶剂。 此外,聚合物是聚偏氟乙烯 - 六氟丙烯共聚物(PVdF-HFP),离子液体是1-乙基-3-甲基咪唑鎓四氟硼酸盐([emim] [BF4])。
