The present invention relates to a separator for a secondary battery which is capable of improving a shut-down function of a cellulose-based multilayer separator physically having high strength. The separator for a secondary battery comprises a substrate formed of cellulose-based nanofibers and polyethylene nanoparticles; and a resin layer stacked on one surface or both surfaces of the substrate, the resin being formed from a polyolefin.

A plastic substrate includes: a plastic support member having light transmittance; and a first organic-inorganic hybrid layer on the plastic support member. The first organic-inorganic hybrid layer includes: a first organic-inorganic hybrid matrix; and ions implanted into the first organic-inorganic hybrid matrix at a side opposite to a side adjacent the plastic support member. An amount of the ions per unit area is in a range from about 2×10.sup.13/cm.sup.2 to about 2×10.sup.14/cm.sup.2.

Regioselectively substituted cellulose esters having a plurality of pivaloyl substituents and a plurality of aryl-acyl substituents are disclosed along with methods for making the same. Such cellulose esters may be suitable for use in films, such as +A optical films, and/or +C optical films. Optical films prepared employing such cellulose esters have a variety of commercial applications, such as, for example, as compensation films in liquid crystal displays and/or waveplates in creating circular polarized light used in 3-D technology.

A thermo-adhesive multilayer film based on thermoplastic polyurethane includes a barrier layer having a material with anti-dye migration properties selected from: ethylene vinyl alcohol copolymer, polyvinyl alcohol, polyvinyl acetate, polyamides, cellulose derivatives, polyvinylidene chloride and combinations. The barrier layer is interposed between two layers, each having a mixture of a thermoplastic polyurethane with a compatibilizing agent selected from: co-polymers modified with maleic anhydride, co-polymers modified with epoxy groups, co-polymers containing hydroxyl groups and combinations thereof. A decorative multilayer film includes the thermo-adhesive multilayer film and a further decorative layer, which provides an aesthetic effect. A process of co-extruding the layers obtains the thermo-adhesive multilayer film and the subsequent bonding thereof with the decorative layer obtains the decorative multilayer film. The decorative multilayer film decorates substrates in the field of textiles, clothing, footwear and accessories. A finished decorated article includes a substrate on which the decorative multilayer film is applied.
