Abstract: A composite membrane for selectively pervaporating a first liquid from a mixture comprising the first liquid and a second liquid. The composite membrane includes a porous substrate comprising opposite first and second major surfaces, and a plurality of pores. A PVP- or PVL-containing polymer is disposed in at least some of the pores so as to form a layer having a thickness within the porous substrate and/or disposed on top of the pores to form a layer.

Abstract: A separation membrane for selectively separating (e.g., pervaporating) a first fluid (e.g., a first liquid) from a mixture comprising the first fluid (e.g., first liquid) and a second fluid (e.g., second liquid), wherein the separation membrane includes a polymeric ionomer that has a highly fluorinated backbone and recurring pendant groups according to the following formula (Formula I): —O—Rf—[—SO2—N−(Z′)—SO2—R—]m—[SO2]n-Q wherein: Rf is a perfluorinated organic linking group; R is an organic linking group; Z+ is H+, a monovalent cation, or a multivalent cation; Q is H, F, —NH2, —NH2, —O−Y+, or —CxF2x+1; Y+ is H+, a monovalent cation, or a multivalent cation; x=1 to 4; m=0 to 6; and n=0 or 1; with the proviso that at least one of morn must be non-zero

Abstract: A thermal insulation/protection barrier that provides thermal insulation and protection to battery cells of a battery assembly. The barrier includes a cured silicone rubber foam layer comprising a plurality of firming particles disposed within the silicone rubber foam layer in an amount sufficient to impart additional firmness to the silicone rubber foam layer so that it takes a greater compressive force to compress the foam layer to a desired compression value, compared to the same silicone rubber foam layer without the firming particles.

Abstract: To provide an electromagnetic shielding material that has excellent shape following properties and can exhibit high electromagnetic wave shielding properties even in a deformed portion. A flexible magnetic film fabric (100) of one embodiment includes a plurality of first magnetic strips (10) extending in a first direction (11) and arranged substantially in parallel at a first pitch P1 along a second direction (12) orthogonal to the first direction (11); and a plurality of second magnetic strips (20) extending in a third direction (21) different from the first direction (11) and arranged substantially in parallel at a second pitch P2 along a fourth direction (22) orthogonal to the third direction (21). Each of the first magnetic strips (10) has a first average width W1, W1/P1 being from 0.05 to 0.98, and each of the second magnetic strips (20) has a second average width W2, W2/P2 being from 0.05 to 0.98.

Abstract: A composite membrane for selectively pervaporating a first liquid from a mixture comprising the first liquid and a second liquid. The composite membrane includes a porous substrate comprising opposite first and second major surfaces, and a plurality of pores. A pore-filling polymer is disposed in at least some of the pores so as to form a layer having a thickness within the porous substrate. The polymer is more permeable to the first liquid than the second liquid but not soluble in the first liquid or the second liquid. The composite membrane may be asymmetric or symmetric with respect to the amount of pore-filling polymer throughout the thickness of the porous substrate.
