For the production of high-performance polyethylene fibers and tapes by ultra drawing, using solid-state processing disentangled nascent ultra-high molecular weight (UHMWPE), maximum draw ratio is an important design parameter, as it determines degree chain alignment and, therewith, properties final product. It would, therefore, be advantageous to have a fast scanning method estimate drawabilit...

Chemically expanded graphite (CEG) has recently been identified as promising reinforcement for polymer composites with the ability commercial up-scaling. In this work, silane and polydopamine functionalized CEG were successfully synthesized employed to prepare ultra-high molecular weight polyethylene (UHMWPE) nanocomposites an enhanced interfacial compatibility. Characterisation of indicated a ...

High molecular weight linear polyethylene, in the form of 7 nm thin single-lamella nanocrystals with a diameter of up to 200 nm, is generated via aqueous catalytic polymerization using the water-soluble catalyst precursor [κN,O-{2,6-(3′,5′-(F3C)2C6H3)2C6H3-NC(H)-(3,5-I2-2-OC6H2)}NiCH3{P(3-C6H4SO3Na)3}] (1-TPPTS). Studies under true pressure reactor conditions using a C-labeled catalyst precurs...

In this paper, the biomedical grade Ultra High Molecular Weight Polyethylene (UHMWPE) has been soaked at different temperatures in Simulated Synovial Fluid (SSF); diffusion coefficient, hardness, roughness and wettability evaluated. Then, 37°C (body temperature) soaked-polyethylene sample was aged 80°C monitored by InfraRed spectroscopy (oxidation trackers) GPC (for molar mass changes) to obser...
