COMPOSITE WITH IMPROVED MECHANICAL PROPERTIES AND MOLDED ARTICLE INCLUDING THE SAME

摘要

The present invention provides a composite obtained by processing a resin composition including a thermoplastic resin, multi-walled carbon nanotubes, and a reinforcing material. The multi-walled carbon nanotubes have an average diameter of 10 nm or more and an Id/Ig of 1 or less. The walls of the multi-walled carbon nanotubes consist of 10 or more layers of graphene. The rate of residual length of the carbon nanotubes present in the composite is 40% or more. The composite has improved mechanical properties without deterioration of conductivity. Due to these advantages, the composite can be used to manufacture various molded articles.

1. A composite obtained by processing a resin composition comprising a thermoplastic resin, multi-walled carbon nanotubes, and a reinforcing material wherein the average diameter of the multi-walled carbon nanotubes is 10 nm or more, the walls of the multi-walled carbon nanotubes consist of 10 or more layers of graphene, the Id/Ig of the multi-walled carbon nanotubes is 1 or less, and the rate of residual length of the carbon nanotubes present in the composite is 40% or more, the rate of residual length being defined by Equation 1:
Rate of residual length (%)=(Content of >500 nm long carbon nanotubes in the composite)/(Content of all carbon nanotubes in the composite)×100  Equation 1
