  • Patent number: 8211969
    Abstract: A dispersion includes non-chemically modified carbon nanotubes, a soluble block copolymer providing at least one block of a conjugated polymer and at least one block of a non-conjugated polymer, and at least one solvent. At 25° C. exclusive of any mechanical force and after one hour, at least 90% of the carbon nanotubes exist in the dispersion as isolated carbon nanotubes. The components of the dispersion can be combined with a polymer miscible with the block copolymer to form a carbon nanotube polymer composite upon removal of the solvent. The dispersion can be cast on a substrate and then dried to form a coating, including forming a superhydrophobic coating on the substrate. The non-conjugated polymer of the block copolymer or another miscible conjugated polymer including a copolymer can include functionalities that non-covalently attach to the carbon nanotube surface, such as for enhanced solubility or enhanced biocompatibility.

  • Patent number: 8143337
    Abstract: A composite material having polymeric resin with disperse phases of reinforcing fibers and nanoparticle materials and its manufacture is disclosed herein. The nanoparticles may be bound together and added to the polymeric resin as microscale aggregations, and then unbound to create a disperse phase of nanoparticles in the resin. In other embodiments, the nanoparticles may be bound to a substrate, such as long fibers, and added to a polymeric resin. The nanoparticles are then unbound from the substrate and dispersed throughout the polymeric resin. The polymeric resin may have multiple components where one component may control the dispersion of the nanoparticles.

  • Patent number: 8137500
    Abstract: Sprayable low-viscosity rubber damping compounds based on liquid rubbers or elastomers and vulcanization agents, which contain small quantities of structure-reinforcing fiber fillers, are notable for the absence of previously usual solid rubbers and have a very low viscosity in the application state. Acoustic compounds of this kind are sprayable with the aid of fully automatic application systems, and are preferably processed at the basic body stage in vehicle construction.

  • Patent number: 8129463
    Abstract: A combination of MWNTs (herein, MWNTs have more than 2 walls) and DWNTs significantly improves the mechanical properties of polymer nanocomposites. A small amount of DWNTs reinforcement (<1 wt. %) significantly improves the flexural strength of epoxy matrix nanocomposites. A same or similar amount of MWNTs reinforcement significantly improves the flexural modulus (stiffness) of epoxy matrix nanocomposites. Both flexural strength and flexural modulus of the MWNTs and DWNTs-coreinforced epoxy nanocomposites are further improved compared with same amount of either DWNTs or MWNTs-reinforced epoxy nanocomposites. In this epoxy/DWNTs/MWNTs nanocomposite system, SWNTs may also work instead of DWNTs. Besides epoxy, other thermoset polymers may also work.

  • Patent number: 8124223
    Abstract: The invention is directed to polyimide based adhesives having a coefficient of thermal expansion (“CTE”) equal to or below 50 ppm/° C. The adhesives of the present invention contain a polyimide base polymer present in the overall adhesive in an amount from 25 to 95 weight percent. The polyimide base polymer has a glass transition temperature (“Tg”) in a range of from about 150 to about 300° C. and typically has a coefficient of thermal expansion above 50 ppm/° C. The polyimide based adhesives of the invention also contain an aramid micro fiber filler in an amount from 5 to 75 weight percent, based upon the total weight of the polyimide based adhesive. The fiber filler can be used to lower CTE of the overall adhesive to match (or nearly match) the CTE of other materials like metal, silicon wafers, other polymers (including polyimide) and the like.
