Abstract
(EN)
The resistive sensor A includes a support with electrodes covered with carbon nanotubes that are functionalised and decorated with metal nanoparticles, the metal nanoparticles thereof supporting a single layer of an organic compound of the group resorcin[4]arene. The invention also relates to a device comprising said resistive sensor A and a resistive sensor B, which is identical to sensor A except that it does not include an organic compound, in order to selectively detect, with increased sensitivity, benzene gas in air. The device is reversible. The method for producing the resistive sensor A comprises selecting a support, designing electrodes, treating the nanotubes with oxygen, decorating them with metal nanoparticles, depositing the nanotubes on the electrodes, preparing a solution of the organic compound and submerging the support in said solution in order to form a single layer of the organic compound.

El sensor resistivo A incluye un soporte con electrodos recubiertos de nanotubos de carbono funcionalizados y decorados con nanopartículas metálicas, cuyas nanopartículas metálicas soportan una monocapa de un compuesto orgánico del grupo resorcin[4]areno. Se protege además un dispositivo que comprende dicho sensor resistivo A y un sensor resistivo B, igual que el sensor A a excepción que no incluye compuesto orgánico, para detectar de manera selectiva y con elevada sensibilidad gas benceno en aire. El dispositivo es reversible. El procedimiento para obtener el sensor resistivo A comprende seleccionar un soporte, dibujar electrodos, tratar los nanotubos con oxígeno, decorarlos con nanopartículas metálicas, depositar los nanotubos sobre los electrodos; preparar una disolución del compuesto orgánico y sumergir el soporte en dicha disolución para formar una monocapa del compuesto orgánico.

L'invention se rapporte à un capteur résistif (A) qui comprend un support doté d'électrodes recouvertes de nanotubes de carbone fonctionnalisés et revêtus de nanoparticules métalliques, lesquelles nanoparticules métalliques supportent une monocouche d'un composé organique du groupe résorcin[4]arène. L'invention concerne en outre un dispositif qui comprend ledit capteur résistif (A) et un capteur résistif (B), analogue au capteur (A) à ceci près qu'il ne comprend pas de composé organique, destiné à détecter sélectivement et avec une sensibilité élevée le benzène gazeux dans l'air. Ce dispositif est réversible. Le procédé d'obtention du capteur résistif (A) consiste à choisir un support, à former les électrodes, à traiter les nanotubes avec de l'oxygène, à les revêtir de nanoparticules métalliques, à déposer les nanotubes sur les électrodes, à préparer une solution du composé organique et à immerger le support dans ladite solution pour former une monocouche de composé organique.
