The invention relates to a layered silicate having interlayer cations, wherein the interlayer cations comprise a) inorganic monovalent cations comprising at least one of Na, K, and Li, and b) organic cations comprising at least one protonated amino acid.

Layered silicate partially modified with amino acid

A process for delamination of a layered silicate in an aqueous medium includes treating a synthetic or naturally occurring 2:1 clay mineral layered silicate with a delamination agent, and contacting the treated layered silicate with an aqueous medium. An amount of the delamination agent used to treat the layered silicate can be at least equal to the cation exchange capacity of the layered silicate. A delaminated layered silicate can be obtained from the process and provided in a dispersion, a composite, or a barrier.

Process for delamination of layered silicates

The present invention relates to sheet silicate lamellae of a 2:1 sheet silicate with a high aspect ratio, to a method for producing these sheet silicate lamellae and to an aqueous dispersion which comprises the sheet silicate lamellae. The present invention further relates to the use of the sheet silicate lamellae of the invention for producing a composite material, and also to a corresponding composite material comprising or obtainable using the sheet silicate lamellae, more particularly for use as a diffusion barrier or as a flame retardant.

Sheet silicate lamellae with a high aspect ratio

Described is an aqueous composition comprising (a) at least one polyanion, (b) at least one ethoxylated cationic polymer, and (c) at least one phyllosilicate. The composition can be used for providing oxygen barrier properties to a polymer film.
