A method of forming a polyolefin-perovskite nanomaterial composite which contains oriented electrically and thermally conductive pathways. The method involves milling a polyolefin with particles of a perovskite nanomaterial, molding to forma composite plate, and subjecting the composite plate to an AC voltage. The AC voltage forms oriented electrically and thermally conductive pathways by partial dielectric breakdown of the composite. The presence of the oriented electrically and thermally conductive pathways gives the polyolefin-perovskite nanomaterial electrical and thermal conductivity and dielectric permittivity higher than the polyolefin alone.

The present disclosure provides a method for preparing a self-floating transparent nano ultrathin film. According to the present disclosure, the MXene film layer and the nano ultrathin film layer are sequentially subjected to suction filtration on the substrate material by utilizing a vacuum suction filtration technology, and thus a double-film structure is loaded on the substrate material; then an oxidant is subjected to oxidizing and bubbling on the MXene film layer in a permeation way, and thus the substrate material and the nano ultrathin film layer can be separated in a physical isolating manner. Finally, the nano ultrathin film is completely separated in a liquid phase floating separation manner. The nano ultrathin film prepared by the method provided by the present disclosure has a specific thickness and light transmittance through different loading capacities, and the substrate material can be repeatedly utilized.

In the method for manufacturing conglomerate stone slabs using the Bretonstone technology, in the variant where the starting mixture is enclosed between two paper sheets, the improvement consists in replacing each paper sheet with a containment element consisting of a paper sheet, one surface of which has, applied thereon, a film of plastic material which is impermeable to organic vapours, impermeable to the liquids and in particular to the liquid resin constituting the binder of said mixture, resistant to the catalysis temperatures of the said resin and resistant to hot solvents and chemical vapours. Preferably, said plastic material is water-soluble, in particular polyvinyl alcohol.

The present disclosure provides device having a reaction vessel with one or more permeable membranes disposed therein that separate the reaction vessel into at least a first portion and a second portion. The one or more membranes permit first reactants from a first solution in the first portion or reactants from a second solution in the second portion to seep or percolate to a reaction zone proximate a surface of the one or more membranes. A reaction of the first and second reactants forms a two-dimensional polymer film material. A roller located inside of the reaction vessel draws the two-dimensional polymer film material reaction out of the reaction zone.
