Abstract
An endless belt comprising a polyimide-based substrate layer. A plurality of boron nitride nanotubes are dispersed in the polyimide.
Claims15
An endless belt comprising:
- a substrate layer comprising polyimide made from precursors comprising at least one dianhydride and at least one diamine;
- and a plurality of boron nitride nanotubes dispersed in the polyimide, the boron nitride nanotubes having a surface area of from about 50 m2/g to about 500 m2/g as determined by BET analysis, and being in an amount ranging from about 0.01 wt. % to about 20 wt. %, based on the total weight of the substrate layer, the substrate layer having a Young's modulus of from about 4,000 MPa to about 10,000 MPa.
