The present invention generally relates to a modular erasable writing panel configured to interconnect with a surface prepared with mounting units. The mounting units provide an interface between a multi-sided modular erasable writing panel and another surface such as a wall, cabinet, or other surface. The writing panel is configured to provide multiple erasable writing surfaces configured to interconnect without adhesive to the mounting units wherein repeated dismounting of the erasable writing surface does not debilitate the adhesive bond between the mounting units and the existing surface. The mounting unit provide micro-suction elements configured to removably interconnect the writing panel with the mounting unit repeatedly without diminishing the holding bond between the mounting unit and the writing panel.

A method for manufacturing a sheet laminate to be affixed to an adherent surface of an object, the method comprising preparing a sheet member having a front surface to become a design surface and a rear surface on which an adhesive part has been formed, bending an edge part of the sheet member by sandwiching the sheet member from a front surface side and a rear surface side in a mold, and heating a part of a bent sheet member. The sheet laminate has a flat part spreading out in a flat plate shape, a side surface on which the edge part bent by the bending step is configured, and a connecting surface protruding and curving toward the front surface side between the flat part and the side surface, and in the heating step, the connecting surface is partially heated after the side surface is molded in the bending step.

A re-useable writing surface reusably and removably coupled to exterior surfaces is disclosed. The re-useable writing surface may include a porous layer. The porous layer may define one or more cells. The re-usable writing surface may further include a non-adhesive coating applied to a side of the porous layer. The re-usable writing surface may further include a writeable layer coupled to a different side of the porous layer. The writeable layer may be configured to allow a user to draft and erase content. The non-adhesive coating can enable the re-useable writing surface to reusably and removably couple to exterior surfaces.

A device for producing an electrode laminate includes a roller configured to press an active material layer-attached current collector layer including a current collector layer and an active material layer disposed on at least one surface of the current collector layer. A diamond-like carbon film having an average roughness of 0.16 μm or less is on a surface of the roller in contact with an active material layer or a press sheet is disposed between the roller and a surface of the active material layer, and a diamond-like carbon film having an average roughness of 0.16 μm or less is on a surface of the press sheet in contact with the active material layer.

An apparatus for making a nonwoven fabric from thermoplastic fibers has a spinneret for spinning fibers into continuous filaments and a cooler for cooling the filaments. The cooled filaments are then deposited on a conveyor to form a nonwoven web. A first consolidator surface treats the nonwoven web with a hot fluid or hot air as it is conveyed on the conveyor. A second consolidating downstream of the first consolidator has a dual-belt furnace in which the nonwoven web is passed between two circulating belts or continuous belts for surface treating the nonwoven web with a hot fluid or hot air and for applying surface pressure can be applied to the nonwoven web at the same time.

A preparation method of a graphene film prepared with flexible polyimide includes the following steps: S1, laminating a plurality of polyimide films; S2, performing heat treatment while pressing the laminated polyimide films for bonding, wherein the temperature of heat treatment is lower than the temperature at which a thermoplastic polyimide film begins thermal decomposition, so that the laminated polyimide films are bonded together to form a polyimide composite film; and S3, raising the temperature of the polyimide composite film to be higher than the temperature at which the polyimide film begins thermal decomposition for heat treatment and carbonization treatment, thereby obtaining a carbonized multifunctional film, and performing graphitization treatment as required. The graphene film prepared by the present invention has ultra-high thermal conductivity, excellent flexibility and bending resistance, anisotropy and good electrical boundary shielding effect and magnetic boundary shielding effect, and a good application prospect.
