  • Patent number: 10773960
    Abstract: A method for controlling density, porosity and/or gap size within a nanotube fabric layer is disclosed. In one aspect, this can be accomplished by controlling the degree of rafting in a nanotube fabric. In one aspect, the method includes adjusting the concentration of individual nanotube elements dispersed in a nanotube application solution. A high concentration of individual nanotube elements will tend to promote rafting in a nanotube fabric layer formed using such a nanotube application solution, whereas a lower concentration will tend to discourage rafting. In another aspect, the method includes adjusting the concentration of ionic particles dispersed in a nanotube application solution. A low concentration of ionic particles will tend to promote rafting in a nanotube fabric layer formed using such a nanotube application solution, whereas a higher concentration will tend to discourage rafting. In other aspects, both concentration parameters are adjusted.

  • Patent number: 10766167
    Abstract: A method of forming a polyolefin-carbon nanomaterial composite which contains oriented electrically conductive pathways. The method involves milling a polyolefin with particles of a carbon nanomaterial, molding to forma composite plate, and subjecting the composite plate to an AC voltage. The AC voltage forms oriented electrically conductive pathways by partial dielectric breakdown of the composite. The presence of the oriented electrically conductive pathways gives the polyolefin-carbon nanomaterial electrical and thermal conductivity higher than the polyolefin alone.
