Abstract: A masterbatch in agglomerated solid form including carbon nanofibers and/or nanotubes and/or carbon black, the content of which is between 15 wt % and 40 wt %, preferably between 20 wt % and 35 wt %, relative to the total weight of the masterbatch; at least one solvent; at least one polymer binder, which represents from 1 wt % to 40 wt %, preferably from 2 wt % to 30 wt % relative to the total weight of the masterbatch. Also, a concentrated masterbatch, characterized in that it is obtained by eliminating all or part of the solvent from the masterbatch described previously. Also, a process for preparing said masterbatches and to the uses of the latter, especially in the manufacture of an electrode or of a composite material for an electrode.

Abstract: Inorganic curable systems, such as cements, plasters, ceramics, or liquid silicates, which can be used, for example, in the fields of building, construction, or the oil-drilling industry. The use of carbon nanofillers for reinforcing the mechanical properties of such systems and for improving the latter. A method for inserting carbon nanofillers, such as carbon nanotubes, in the form of a binder master batch, into an inorganic curable system with a view to preparing composite materials having improved properties.

Abstract: A method for producing a fibrous material including carbon fibres or glass fibres or plant fibres or polymer-based fibres, that are used alone or in a mixture, and are impregnated by a thermohardenable polymer using a mixture containing a hardener and carbon nanofillers, such as carbon nanotubes (CNT). A mixture containing said nanofillers, such as CNTs, and the hardener is used to introduce said nanofillers into the fibrous material. A continuous production line (L) for producing the material in the form of at least one calibrated and homogeneous strip (20) of reinforcing fibres impregnated with a thermohardenable polymer, includes the device (100) for arranging two series of fibres (1, 2) used to form a strip in such a way as to arrange the two series of fibres such that they are brought into contact with each other by means of two calendering devices.

Abstract: The present invention relates to a masterbatch in agglomerated solid form comprising: a) carbon nanofibers and/or nanotubes and/or carbon black, the content of which is between 15 wt % and 40 wt %, preferably between 20 wt % and 35 wt %, relative to the total weight of the masterbatch; b) at least one solvent; c) at least one polymer binder, which represents from 1 wt % to 40 wt %, preferably from 2 wt % to 30 wt % relative to the total weight of the masterbatch. The present invention also relates to a concentrated masterbatch, characterized in that it is obtained by eliminating all or part of the solvent from the masterbatch described previously. It also relates to a process for preparing said masterbatches and to the uses of the latter, especially in the manufacture of an electrode or of a composite material for an electrode.

Abstract: Provided are methods for dissolving polyamides under ambient conditions and for forming polyamide nanofibers by electrospinning. Also provided are methods for incorporating nanoparticles, including nanotubes, into such nanofibers.
