Epoxy insulated carbon fiber and carbon nanotube fiber microelectrodes
Sensors and Actuators B: Chemical, 2013 Carbon-fiber microelectrodes (CFMEs) are typically constructed from glass capillaries pulled to a fine taper or from a polyimide-coated capillary that is 90 μm in outer diameter. Here, a new fabrication method is developed to insulate carbon-fiber microelectrodes with a thin epoxy coating.

Preparation of Carbon Fiber/Carbon Composites Using Intercalated Carbon Fibers
TANSO, 1992 Carbon fiber/carbon composites were prepared from carbon fibers intercalated with AlCl3 as reinforcements, and coal tar pitch or phenol resin as matrix precursor. A1C13, which is known to have a catalytic effect on the carbonization process, was de-intercalated from carbon fibers during the preparation of composites, i.e.
