Nano-composite films and methods for their fabrication. The nano-composite films include a polymer matrix (e.g., polyethylene, polypropylene, or the like) and a filler capable of exfoliation such as graphene or hexagonal boron nitride (e.g., TrGO). The filler provides reinforcement, increasing tensile strength, Young's modulus, or both for the resulting nano-composite film, as compared to what it would be without the filler. The nano-composite film may have a specific tensile strength that is greater than 1 GPa/g/cm.sup.3, a specific Young's modulus that is greater than 100 GPa/g/cm.sup.3, or both. Tensile strength and modulus values of up to 3.7 GPa/g/cm.sup.3 and 125 GPa/g/cm.sup.3, respectively, have been demonstrated. The film may be formed by combining powdered filler and polymer matrix powder in a solvent (e.g., decalin), high-shear extruding the resulting solution to disentangle the polymer chains and exfoliate the filler, freezing the solution to form a solid film, and then drawing the film.

In a process for the production of a textile clothing item with at least one abrasion protection zone provided with protector elements, the following steps are provided: 1) Provision of a textile backing layer (1) that is expandable and is provided in the form of a tube open on both sides (1), into which a support element (2) is introduced before the application of the coating material (5), by means of which the tube (1) is pre-extended and stretched free of wrinkles in the abrasion protection zones provided. 2) Provision of a pasty, hardenable coating material (5); 3) Application of a large number of portions of the coating material (5) on a surface of the backing layer for the formation of the protector elements, whereby the portions of the coating material (5) are arranged on the surface in such a way that the portions do not overlap and only a portion of the surface of the backing layer is covered by the coating material (5). A metallic molding plate (10, 20) that contains a large number of concave form cavities (11, 21) for the formation of the protector elements (101), which are filled with the pasty coating mass (5) and which is applied, with its openings, to the tube (1) supported on the support plate (2), is used for that purpose. 4) Hardening of the coating material (5) during the application of temperature for the formation of a large number of hard protector elements on the backing layer.

The present disclosure discloses a method for recycling a residue from MXene preparation, including the following steps: recovering a bottom residual sediment produced in preparation of MXene through etching in a minimally intensive layer delamination (MILD) method, mixing the bottom residual sediment with a molten polyvinyl alcohol (PVA) solution, and drying to prepare a Ti.sub.3C.sub.2T.sub.x-Ti.sub.3AlC.sub.2/PVA composite film. The present disclosure can effectively utilize a residue from an MXene process to prepare a composite film with both excellent mechanical properties and electrical conductivity.
