Patent number: 8129463Abstract: 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.Type: GrantFiled: March 29, 2007Date of Patent: March 6, 2012Assignee: Applied Nanotech Holdings, Inc.Inventors: Dongsheng Mao, Zvi Yaniv

Patent number: 8124223Abstract: 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.Type: GrantFiled: August 2, 2010Date of Patent: February 28, 2012Assignee: E.I. du Pont de Nemours and CompanyInventors: Kuppusamy Kanakarajan, Arnold Frances
