摘要:
An organic/inorganic composite membrane may include hydrophilic inorganic particles dispersed in an organic polymer matrix having finger-like pores. The hydrophilic inorganic particles may be present at a higher concentration near one surface of the membrane having a higher density than the other surface of the membrane having a lower density.

A separator for a rechargeable lithium battery and a rechargeable lithium battery, the separator including a substrate, and a heat-resistant porous layer on at least one side of the substrate, the heat-resistant porous layer including an imide-based copolymer, wherein the imide-based copolymer includes a first repeating unit represented by Chemical Formula 1 and a second repeating unit represented by Chemical Formula 2:
摘要:
A semi-permeable membrane may include a support layer and an active layer in contact with the support layer. The support layer includes a porous structure including a polymer and at least one metal (or metalloid) oxide in the porous structure. In the support layer, the amount of the metal (or metalloid) oxide present in a portion adjacent to the active layer is higher than the amount of the metal (or metalloid) oxide present in a portion farther from the active layer.
