Abstract: A size-adjustable woven fabric comprises a first set of threads (10a-10i), each formed of a heat-shrink polymer material, at least one conducting thread (20), formed of an electrically conducting material, wherein the first set of threads (10a-10i) runs substantially parallel with each other, and wherein the conducting thread (20) runs substantially across the first set of threads (10a-10i). There is further disclosed a wearable item comprising such a size-adjustable fabric, as well as methods of expanding and reducing size of such a size-adjustable fabric. There is further disclosed footwear and protective wear comprising such size-adjustable fabric.

Abstract: A method for inserting 2D flakes of a two dimensional material into pores of a porous substrate comprises providing a porous substrate having a plurality of open pores, wherein at least some of the pores contain a gas, applying a liquid dispersion of flexible 2D flakes of a two dimensional material to the porous substrate; subjecting said porous substrate and said liquid dispersion to a vacuum, such that the gas is evacuated from the pores, causing the liquid dispersion to be introduced into the pores and removing the liquid from the pores, so as to leave the 2D flakes in the pores.

Abstract: The present disclosure provides a method for redistributing a flake material, in particular a two-dimensional nano flake material, into at least two flake size fractions, each of which having smaller flake size variance than the flake material. The method comprises providing a dispersion of the flake material in a liquid, wherein the flake material is not atomized in the liquid, arranging the dispersion in a container, percolating gas bubbles upwardly through the dispersion, for a time sufficient to allow the flake material to redistribute itself in the liquid with larger sized flakes higher up in the liquid and smaller sized flakes lower down in the liquid, and extracting at least one of the flake fractions from a limited vertical level of the container.
