Embedded nanotube array sensor and method of making a nanotube polymer composite

Abstract

A method of producing polymer/nanotube composites where the density and position of the nanotubes within the composite can be controlled. Carbon nanotubes are grown from organometallic micropatterns. These periodic nanotube arrays are then incorporated into a polymer matrix by depositing a curable polymer film on the as-grown tubes. This controlled method of producing free-standing nanotube/polymer composite films may be used to form nanosensors which provide information regarding a physical condition of a material, such as an airplane chassis or wing, in contact with the nanosensor.

1 . An antenna, comprising an array of substantially aligned carbon nanotubes or carbon nanofibers embedded in a matrix material wherein carbon nanotubes or carbon nanofibers are adapted to function as an antenna by wirelessly receiving and/or transmitting information. 
     
     
         2 . The antenna of  claim 1 , wherein the antenna further comprises a send/receive circuit electrically connected to the carbon nanotubes or carbon nanofibers. 
     
     
         3 . The antenna of  claim 1 , wherein the carbon nanotubes or carbon nanofibers are substantially aligned in at least one conductive channel in the matrix material.
