ABSTRACT:
A poly(ether-ketone) composite of the formula:wherein CNF is carbon nanofibers and MWNT is multi-walled carbon nanotubes; wherein Ar represents ether-ketone repeating groups of the formulawherein Q is —O— or —O—(CH2)n—O—, wherein n has a value of 2-12; wherein R is —H, —CH3, or —C2H5, m has a value of 1 or 2; wherein R′ is —H or —CH3; and wherein — denoted the presence of a direct C—C bond between Ar and CNF or MWNTgAlso provided is a process for preparing the composite.
