  • Method of making a fuser member
    Patent number: 10501659
    Abstract: Described herein is a method of manufacturing a fuser member. The method includes mixing a high load fluoropolymer/carbon nanotube composition in a high shear mixer. The method includes mixing the high load fluoropolymer/carbon nanotube composition in the high shear mixer for 3 or more times. A fluoropolymer is added to the high load fluoropolymer/carbon nanotube composition to form a low load fluoropolymer/carbon nanotube composition. The low load fluoropolymer/carbon nanotube composition is mixed in a rubber compounding mixer for 3 or more times. The low load fluoropolymer/carbon nanotube composition is coated on a fuser substrate, cured and polished.
