▎ 摘　　要

NOVELTY - Polyimide composition comprises a polyimide, where the polyimide is a polymeric reaction product of a dianhydride and one or more diamines. The diamines comprises a fluorine-containing alkyl ether diamine, and one or more thermally conductive fillers. The thermally conductive fillers comprise one or more of a carbon-based filler, boron nitride, a metal, or combinations. The composition comprises a thermal conductivity of from about 0.2-50 Watts per meter Kelvin (Wm-1 K-1). USE - Compositions for compliant rollers of automated fiber placement (AFP) machines having improved properties and methods for the same. ADVANTAGE - The thermally conductive fillers may be capable of or configured to increase or improve the dissipation of heat in the materials. Functionalization of the carbon-based fillers may at least partially facilitate the dispersion of the carbon-based fillers within the materials. The composition is utilized in the fabrication of the compaction roller of the AFP machine. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) a roller, which comprises the composition; and (2) a compaction roller for an automated fiber placement machine, which comprises a body having an outer layer, where the outer layer of the body comprises the composition. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a portion of an automated fiber placement machine.
