Abstract:

Tire cords comprising fibers including at least one polymer and graphene sheets. Graphene sheets are added to poly(ethylene terephthalate) (PET) by melt compounding in an extruder to yield a PET compn. comprising about 0.25 wt.% graphene sheets. The PET compn. is then solid phase polymd. at 215° to an IV of about 1 dL/g. The compn. is spun into monofilaments that are then post drawn to a draw ratio of about 4 to 5. After drawing, the filaments have a diam. of about 120 μ. The storage modulus of the monofilaments is then measured as a function of temp. using a dynamic mech. analyzer (DMA). [on SciFinder(R)]
