Uhmwpe Fibers

MWCNT/Ultrahigh-molecular-weight polyethylene (MWCNT/UHMWPE) composite was prepared by adding purified MWCNTs into the precursor solution of UHMWPE. Based on that, MWCNT/UHMWPE fibers were obtained using a gel spinning-molding technique. The thermal, mechanical and aggregation structure of MWCNT/UHMWPE fibers were characterized by TGA, mechanical property measurement and XRD, respectively. The results indicated the incorporation of MWCNTs into UHMWPE macromolecular chains have not change the aggregation structure of UHMWPE significantly, and the as-prepared MWCNT/UHMWPE fibers have evidently improved thermal stability and mechanical strength compared with the pristine UHMWPE fibers.

Different Temperatures

A series of ultrahigh molecular weight polyethylenes with viscosity-average molecular weights in the range of 1.6–5.6 × 106 have been prepared by using a novel Ziegler–Natta-type catalytic system—TiCl4/2,2′-dimethoxy-1,1′-binaphthalene/Et3Al2Cl3/Bu2Mg at different temperatures (Tpoly) in the range between 10 and 70 °C in toluene. The morphology of the nascent reactor powders has been studied by scanning electron microscopy, wide-angle X-ray diffraction, and the DSC melting behavior. Polymers are suitable for the modern processing methods—the solvent-free solid-state formation of super high-strength (tensile strength over 1.8–2.5 GPa) and high-modulus (elastic modulus up to 136 GPa) oriented film tapes. With decrease of Tpoly, the drawability of the reactor powders increased significantly.
