An electric cable has at least one elongated electrical conductor (), at least one electrically insulating layer () surrounding the elongated electrical conductor (), and at least one metal layer () surrounding electrically insulating layer (). The metal layer () has metal nanowires.

Electric cable comprising a metal layer

Isolating metal nanowires from a reaction mixture also containing ancillary inorganic particles distinct from the nanowires, includes: providing a mixture of metal nanowires with large particles having at least two dimensions 250 nm or more, and small particles of which the largest dimension is less than 200 nm, in the form of a dispersion in a solvent medium having a viscosity at 25&#xb0; C. 10 mPa&#xb7;s or more; leaving the mixture to settle out under conditions conducive to the formation of a supernatent phase including the small particles and of a precipitate comprising the metal nanowires and the large particles; isolating the precipitate, and dispersing the isolated precipitate in a solvent medium having a viscosity at 25&#xb0; C. less than 10 mPa&#xb7;s; leaving the suspension to settle out under conditions conducive to the precipitation of said large particles; and recovering the nanowires in the form of a dispersion in the supernatent phase.

Process for purifying metal nanowires

The invention relates to a display screen and its manufacturing process. The display screen of the invention comprises: a substrate made of a plastic; at least one transparent heating element; and at least one thermochromic compound, and is characterized in that the at least one transparent heating element comprises at least one optionally functionalized metal nanowire. The invention in particular has applications in the electronics industry.

Display screen and its manufacturing process

The invention relates to an electronic device comprising at least two organic transistors having different threshold voltages. The device comprises at least two transistors, each including a self-assembled layer of molecules having dipole moments that differ from one another by an absolute value of between 0.2 and 10 debye. The invention is particularly suitable for use in the field of electronic circuit production.

Use of self-assembled layers for checking the threshold voltage of organic transistors

The invention relates to a process for improving the electrical and optical performance of a transparent electrically conductive material having silver nanowires. The invention also relates to a process for manufacturing a film made of a transparent electrically conductive material, such as a transparent electrode, a transparent heating film, or a film for electromagnetic shielding. The process of the invention includes the following steps: a) a step of bringing silver nanowires into contact with an acid solution, this solution having a pH lower than 7, preferably lower than 3; and b) a step of eliminating the acid. The field of application of the invention is in particular the field of optoelectronics.
