  • Process for preparation of polyethylene nanocomposite
    Patent number: 10800907
    Abstract: The invention provides a process for preparation of a polyethylene nanocomposite comprising dispersing a base polyethylene resin and planar carbon nanoparticles in an inert liquid at conditions under which the base polyethylene resin is not solubilised in the inert liquid, and removing an amount of the liquid sufficient to provide a dispersion of the planar carbon nanoparticles in the base polyethylene resin.
    Type: Grant
    Filed: January 13, 2017
    Date of Patent: October 13, 2020
    Assignee: QENOS PTY LTD
    Inventors: Philip Adetunji, Minoo Naebe, Paul Frigo, Brian Egan
  • Polymer resin composition and articles formed with the composition
    Patent number: 10626243
    Abstract: A polyethylene nanocomposite composition comprising: (i) base polyethylene resin of medium density polyethylene or high density polyethylene resin having a melt flow index in the range of from 0.10 to 1.4 g/10 min at 190° C. and 5 kg as measured according to ISO 1133, high load melt flow index of from 4 to 20 g/10 min at 190° C. and 21.6 kg as measured according to ISO 1133 and a density in the range of from about 0.930 to about 0.970 g/cm3 at 23° C. as measured according to ASTM D792; and (ii) planar carbon nanoparticles having a BET (from Brunauer-Emmett-Teller (BET) theory) surface area of at least 50 m2/g, in an amount of from 0.1% to 20% by weight based on the weight of the polyethylene nanocomposite composition.
