Ultrahigh-Molecular-Weight Polyethylene Fibers with Excellent Creep Resistance Derived from an Online-Tailored Fish-Skeleton-like Molecular Structure
Ultrahigh-molecular-weight polyethylene (UHMWPE) fibers with high creep resistance are widely used in ocean mooring cables, ship cables, and marine fisheries. Conventional methods of preparing creep-resistant UHMWPE fibers focus on postmodification, which significantly limits application in complex environments. Therefore, in this study, we prepared highly creep-resistant UHMWPE fibers with a molecular structure similar to that of a fish skeleton. First, the components of the spinning solution were combined proportionally, and an initiator and 1-hexene were added in varying amounts. Modified UHMWPE fiber products with polymer chain slip hindrance were prepared by melt-grafting spinning and hyperthermal drafting. The elongation declined markedly when the content of the added monomer increased to 5.0%, and the elongation decreased from 8.5 to 2.5% at a temperature of 70 °C, representing an improvement of more than 70%. This method solves the low efficiency problems encountered in conventional industrial modification methods, difficulty in modification via online spinning, and high creep resistance. This method is simple, cost-effective, and universally applicable.
期刊介绍：
Macromolecules publishes original, fundamental, and impactful research on all aspects of polymer science. Topics of interest include synthesis (e.g., controlled polymerizations, polymerization catalysis, post polymerization modification, new monomer structures and polymer architectures, and polymerization mechanisms/kinetics analysis); phase behavior, thermodynamics, dynamic, and ordering/disordering phenomena (e.g., self-assembly, gelation, crystallization, solution/melt/solid-state characteristics); structure and properties (e.g., mechanical and rheological properties, surface/interfacial characteristics, electronic and transport properties); new state of the art characterization (e.g., spectroscopy, scattering, microscopy, rheology), simulation (e.g., Monte Carlo, molecular dynamics, multi-scale/coarse-grained modeling), and theoretical methods. Renewable/sustainable polymers, polymer networks, responsive polymers, electro-, magneto- and opto-active macromolecules, inorganic polymers, charge-transporting polymers (ion-containing, semiconducting, and conducting), nanostructured polymers, and polymer composites are also of interest. Typical papers published in Macromolecules showcase important and innovative concepts, experimental methods/observations, and theoretical/computational approaches that demonstrate a fundamental advance in the understanding of polymers.
