Abstract: Novel coating compositions are disclosed for use in Energy Storage devices and Additive Manufacturing. The coatings are comprised of discrete carbon nanotubes wherein the coatings have a selected range of porosity, and optionally 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 with a dimension larger than about 5 micrometers The coatings are of average thickness from about 5 nanometers to about 2000 nanometers and can be applied onto particles of diameter less than about 1000 micrometers, or films. Improved energy storage, or additive part performances include, but not limited to, higher electron conductivity for electrodes of energy storage devices, and higher electron conductivity for parts made by additive manufacturing. The coatings are particularly suitable for additive manufacturing of energy storage devices, and electrodes made using a dry electrode process.

Abstract: A sized reinforcing filler, comprising a filler and a sizing agent disposed on at least a portion of the filler, to be used for reinforcement for plastics is disclosed. The sizing agent is based upon at least one of a polyvinyl alcohol, an ethylene/vinyl alcohol copolymer, a silane-grafted polyvinyl alcohol and a silane-grafted ethylene/vinyl alcohol copolymer, a silane-grafted polyvinyl alcohol and a silane-grafted ethylene/vinyl alcohol copolymer. The polyvinyl alcohol is useful as a size for all types of fibers and particles to reinforce all types of commodity and engineering plastics, particularly polyolefin resins, to form polymer composites. As such, polymer composites reinforced with such sized reinforcing fillers, as well as articles, components, and products including such polymers composites, are also disclosed.

Abstract: The present disclosure relates to masterbatch compositions comprising a base polymer and carbon black and carbon nanotubes as filler that can be used to prepare an article with improved electrical or mechanical performance relative to a masterbatch having carbon black filler alone. The masterbatch compositions can also be used to prepared colored articles without sacrificing electrical or mechanical performance as is typically seen with highly-loaded carbon black-filled compositions.
