    Abstract: The present invention relates to the development of carbon fiber carbon nanotubes reinforced polymer composites for high strength structural applications. It is very difficult to incorporate higher amount of carbon fiber >60 vol % in any of the polymer matrix. Beyond this loading the mechanical properties of these composite starts deteriorate. Therefore, further improvement in the mechanical properties is not possible. Herein, a novel method is developed to fabricate the hybrid carbon fiber epoxy composites reinforced with multiwalled carbon nanotubes. The flexural strength of the hybrid composites (˜45 vol % CF+CNT) was achieved more than 600 MPa which is more than 35% over pure carbon fiber/epoxy composites (˜50 vol % CF). These high strength hybrid composites can be used in wind mill blades, turbine blades, sport industries, automobile and airframe.

  • Patent number: 9175124
    Abstract: The present invention relates to an elastomer mixture resulting from the modification of a diene elastomer by a coupling agent that introduces, into the elastomer chain, an alkoxysilane group bearing a tertiary or secondary amine functional group. This mixture predominantly comprises the diene elastomer coupled by the alkoxysilane group bearing a tertiary or secondary amine functional group which is bonded to the diene elastomer through the silicon atom. The invention also relates to a reinforced rubber composition, in particular that can be used for the manufacture of tires, which comprises a reinforcing filler and an elastomer matrix comprising at least this elastomer mixture, and to its preparation process. This composition has improved hysteresis and mechanical properties in the vulcanized state, and also improved processing in the uncured state.

  • Patent number: 9084989
    Abstract: Polyhydroxyfullerenes (PHFs) having enhanced electron scavenging capabilities have a ratio of non-hydroxyl functional groups to hydroxyl functional groups that is less than or equal to 0.3. When combined with a semiconductor photocatalyst, such as titanium dioxide nanoparticles, the PHFs provide a photocatalyst for degradation of chemical and biological contaminates with an efficiency of at least twice that of titanium dioxide nanoparticles free of PHFs. The PRFs are included in these catalysts at a weight ratio to titanium dioxide of about 0.001 to about 0.003, whereas significantly lower and higher ratios do not achieve the highly improved photodegradation capability. PHFs outside of the desired structure are shown to be of little value for photodegradation, and can be inhibiting to the photocatalytic activity of TiO2. The enhanced electron scavenging PHFs can be employed as a component of materials for solar cells, field effect transistors, and radical scavengers.

  • Publication number: 20150148459
    Abstract: The deposition of graphene is accomplished by various techniques that result in a change of the graphene's solubility in the liquid medium. The solubility change enables the deposition of the graphene onto the substrate. Once the graphene is deposited onto the substrate, the at least partially coated substrate may be separated from the liquid medium. The substrates may then serve as a carrier to deliver the graphene to a desired application.
