Title: The Innovative Contributions of Chunsheng Du
Introduction
Chunsheng Du is a prominent inventor based in Davis, CA, known for his significant contributions to the field of carbon nanotube technology. With a total of 2 patents, his work focuses on synthesizing small-diameter carbon nanotubes and developing high power density supercapacitors.
Latest Patents
One of his latest patents is a method of synthesizing small-diameter carbon nanotubes with electron field emission properties. This patent discloses a carbon nanotube material with an outer diameter of less than 10 nm and a number of walls less than ten. It also describes an electron field emission device that includes a substrate, an optional adhesion-promoting layer, and a layer of electron field emission material. The electron field emission material consists of carbon nanotubes with a specific number of concentric graphene shells, an outer diameter ranging from 2 to 8 nm, and a nanotube length greater than 0.1 microns. The fabrication method involves producing a catalyst containing Fe and Mo supported on MgO powder, using a mixture of hydrogen and carbon-containing gas as precursors, and heating the catalyst to a temperature above 950°C.
Another notable patent involves high power density supercapacitors with carbon nanotube electrodes. This invention provides a process for fabricating an electrode for a capacitor using carbon nanotubes. The process begins with dispersing CNTs in a solvent to form a suspension, charging the CNTs, and immersing a metal substrate in the suspension. The CNTs are then deposited onto the metal substrate using electrophoretic deposition, forming a layer of active material without using a binder, which effectively reduces contact resistance.
