Abstract: A separator for a rechargeable battery includes a porous substrate and a heat-resistance layer on at least one surface of the porous substrate. The heat-resistance layer includes a binder having a cross-linked structure, a sphere-shaped filler, and a plate-shaped filler, and the plate-shaped filler is included in a smaller amount than the sphere-shaped filler in the heat-resistance layer. A rechargeable battery includes the separator.

Abstract: A hybrid porous structured material may include a porous region and a non-porous region. The porous region may include an imaginary stacked structure, wherein a plurality of imaginary spherical bodies/cavities are stacked so as to contact each other in three-dimensional directions. The non-porous region fills the gaps between the imaginary spherical bodies. A spherical colloid particle is present in each of the plurality of imaginary spherical bodies in the porous region. A separation membrane may include the hybrid porous structured material. A water treatment device may include the membrane.

Abstract: A thermosensitive copolymer may include a first repeating unit having a temperature-sensitive oligomer and a second repeating unit having an ionic moiety and a counter ion to the ionic moiety. The temperature-sensitive oligomer may be an oligomer including a repeating unit derived from a unsaturated monomer with a moiety represented by Chemical Formula 1 or Chemical Formula 2, or an oligomer including a repeating unit derived from a heterocyclic compound having C, N, O, and a C═N bond in its ring. *—C(═O)N(R2)(R3)  [Chemical Formula 1] R2 and R3 may each independently be hydrogen or a linear or branched C1 to C6 alkyl group, a C3 to C7 cycloalkyl group, or a C6 to C10 aryl group, R2 and R3 may not both be hydrogen, and R2 and R3 may be combined to form a nitrogen containing heterocycle. R4 may be a C2 to C5 alkylene group.
