  • Patent number: 11519103
    Abstract: The present disclosure relates to a process for preparing carbon fibers. The process involves blending a carbon nano-material with a carbon material to obtain a homogenous blend, heating the homogenous blend to obtain mesophase pitch having particles with reduced mesophase sphere size followed by spinning the mesophase pitch to obtain the pitch fibers. The pitch fibers are then carbonized to obtain the carbon fibers. The carbon fibers prepared by the process of the present disclosure have improved tensile properties as compared to the conventional pitch based carbon fibers.
    Type: Grant
    Filed: November 2, 2018
    Date of Patent: December 6, 2022
    Assignee: Reliance Industries Limited
    Inventors: Swanand Dilip Patil, Rupesh Arun Khare, Padmavathi Nandigam, Asmita Ashok Khanvilkar, Sreekumar Thaliyil Veedu

  • Patent number: 10472241
    Abstract: The present disclosure relates to a process for the synthesis of highly crystalline carbon nanotubes (CNTs). Processes known in the art employ post-synthesis processes such as oxidation or hydrothermal treatment to produce CNTs with high crystallinity. The present disclosure produces highly crystalline CNTs at a low growth temperature and without hydrogen flow condition and without employing any post-production process. The process disclosed in the present disclosure produces CNTs having a crystallinity greater than 5 which makes them suitable for various industrial applications.

  • Patent number: 7288238
    Abstract: The present invention involves alewives of highly aligned single-wall carbon nanotubes (SWNT), process for making the same and compositions thereof. The present invention provides a method for effectively making carbon alewives, which are discrete, acicular-shaped aggregates of aligned single-wall carbon nanotubes and resemble the Atlantic fish of the same name. Single-wall carbon nanotube alewives can be conveniently dispersed in materials such as polymers, ceramics, metals, metal oxides and liquids. The process for preparing the alewives comprises mixing single-wall carbon nanotubes with 100% sulfuric acid or a superacid, heating and stirring, and slowly introducing water into the single-wall carbon nanotube/acid mixture to form the alewives. The alewives can be recovered, washed and dried. The properties of the single-wall carbon nanotubes are retained in the alewives.
