  • Dispersions for additive manufacturing comprising discrete carbon nanotubes
    Patent number: 12291058
    Abstract: The present invention is directed to additive manufacturing compositions and methods for producing additive manufacturing composite blends with oxidized discrete carbon nanotubes with dispersion agents bonded to at least one sidewall of the oxidized discrete carbon nanotubes. Such compositions are especially useful when radiation cured, sintered or melt fused.
    Type: Grant
    Filed: March 25, 2021
    Date of Patent: May 6, 2025
    Assignee: MOLECULAR REBAR DESIGN, LLC.

  • Novel Compositions Particles, Powders, Pellets or Strands Coated With Discrete Carbon Nanotubes
    Publication number: 20250122384
    Abstract: Novel compositions for producing particles, powders or strands with coatings of discrete carbon nanotubes wherein the coatings have a selected a range of porosity and the discrete carbon nanotubes have selected surface modifications to improve wetting or flow of material through the pores of the carbon nanotube coating. The coatings have less than about 20% mass of bundles or ropes of carbon nanotubes larger than about 5 micrometers thereby improving performance of the printed parts. The compositions may include coatings of a thickness from about 5 nanometers to about 5000 nanometers on particles of diameter less than about 5000 micrometers or polymer strands wherein the coating includes discrete carbon nanotubes and/or surface modification of the discrete carbon nanotubes.
