Phillippe Lodefier has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Masterbatches for preparing a composite material based on semi-crystalline polymer with enhanced conductivity properties, process and composite materials produced therefrom
    Publication number: 20200148840
    Abstract: The present invention relates to a masterbatch for use in a process of preparing a composite material comprising a blend of a first semi-crystalline polymer with at least 5 wt % carbon nanotubes. Good dispersion of the carbon nanotube is obtained within the masterbatch and evidenced by the blending of the masterbatch with a second semi-crystalline polymer miscible with the first one in respective proportions to obtain a composite material containing about 1 wt % of carbon nanotubes wherein said composite material yields an agglomerate area fraction U % lower than 2 and a surface resistivity lower than 105 ohm/sq.
    Type: Application
