Abstract

A method for increasing the thickness of a sheet of CNTs (146, 147, 246, 346), comprising: providing a wet sheet of CNTs, wherein the sheet of CNTs is either a continuous sheet of CNTs or a portion of sheet of CNTs, wherein the wet sheet of CNTs is the result of applying a process for manufacturing a sheet of CNTs; separating the wet sheet of CNTs from any filter or support element; drying the wet sheet of CNTs (146, 147, 246, 346) by applying heat (15, 25, 35) from a heat source (12, 22, 32). A method for manufacturing a continuous sheet of CNTs, comprising: in a container (41) filled with a liquid solution (42) comprising CNTs at certain concentration, submerging a vacuum tank (43) having a lower surface forming a grillage; moving an elongated filtering membrane (44) along the lower surface of the vacuum tank (43) while vacuum is applied on the elongated filtering membrane (44) in such a way that in the surface of the filtering membrane (44) opposed to the surface in contact with the lower surface of the vacuum tank (43) CNTs are deposited forming a continuous sheet of CNTs (45) of constant thickness; taking the filtering membrane (44) together with the continuous sheet of CNTs (45) out of the container (41); washing the continuous sheet of CNTs (55) disposed on the filtering membrane or on a support element (54) in a second container (51) filled with cleaning solution (52); taking the continuous sheet of CNTs (55) together with the filtering membrane or the support element (54) out of the second container (51); separating the continuous sheet of CNTs (55) from the filtering membrane or the support element (54); drying the continuous sheet of CNTs (55) by applying the method for increasing the thickness of a sheet of CNTs.
