  • Process For Preparing Polymeric Fibers Comprising Thermotropic Liquid Crystalline Polymer And Carbon Nanotubes
    Publication number: 20140080993
    Abstract: The invention relates to polymeric fibers and a process of preparing polymeric fibers. The process comprises the steps of synthesizing a composite of thermotropic liquid crystalline polymer (TLCP) comprising multi-walled carbon nanotubes (MWNTs), and spinning the composite to form composite fibers. Specifically, the MWNTs are incorporated at a very low concentration. It is demonstrated that the as-spun TLCP/MWNTs composite fibers demonstrated significantly enhanced mechanical properties as compared with the control TLCP fibers without MWNTs. Fibers having 0.3 wt % MWNTs (C-3) demonstrated an increase of tensile modulus and strength by 38% and 32%, respectively, when compared with the control TLCP fiber without MWNTs.
