NOVELTY - Inserting 2 (dimensional) D flakes of a two dimensional material into pores of a porous substrate, comprises: providing a porous substrate having open pores, where 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; and subjecting the porous substrate and the liquid dispersion to a vacuum, 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. USE - The method is useful for inserting 2 D flakes of two dimensional material into pores of porous substrate. ADVANTAGE - The method: utilizes liquid dispersion that to advantageously having flakes with controlled surface area (lateral size), having average lateral size with statically distribution of low variance, that the flakes can be supplied to the porous substrate with suitable lateral sizes for the substrate; utilizes materials can provide, is that in case of impregnation of flakes of highly conductive materials (graphene) into the substrate with high porosity - which allows interconnections of impregnated flakes-it is possible to obtain electrically conductive materials; and is advantageous separate flakes of appropriate size, into separate liquid dispersion. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) porous composite material, comprising a porous substrate comprising a solid material enclosing open pores, flexible 2D flakes of a 2D material distributed within the porous substrate, where at least some of the pores have an opening providing a restricted flow path into the respective pore, where the size of the 2D flakes cause them to be retained in the pores by the openings; and (2) composite material, comprising a substrate in the form of a textile, composed of interlaced, and optionally bonded, fibers and/or threads, where the fibers or threads are individually coated by flexible 2D material flakes.
