Micro Fabrication of CNT based fibers

The discovery of carbon nano tubes (CNTs) was a major breakthrough on a technological front. But, these CNTs have largely failed to relate to the real world problems because of the difficult material synthesis and laborious processing. These multifunctional carbon nanotubes (CNT) fibers combine the specific strength, stiffness, and thermal conductivity of carbon fibers with the specific electrical conductivity of metals. But realizing these excellences in practical applications needs to assemble individual CNTs into larger scale products. In this paper, we review some key spinning techniques like spinning from a vertical aligned CNT arrays, Electrophoretic spinning, spinning from CNT aerogel and solution spinning techniques include surfactant based spinning, liquid crystal based solution spinning
