Latest Patents

Sakamoto's latest patents include a novel process for producing pitch carbon fibers. In one of his processes, he describes the method of producing pitch carbon fibers by melt-spinning a carbonaceous pitch. The resulting pitch fibers undergo an infusiblization treatment after the application of a dimethyl polysiloxane, which has a viscosity at 25°C ranging from 0.5 to 500 cSt. This treatment is followed by washing and carbonization. Another patent outlines a similar process, where pitch fibers obtained from melt-spinning are subjected to infusibilization and carbonization treatments. In this case, a dimethyl polysiloxane with a viscosity of 12,000 to 1,000,000 cSt is applied after infusibilization, enhancing the carbonization process.
