Abstract
En 中文
Ultra-high-molecular-weight polyethylene (UHMWPE) occupies a uniquely distinguished position among semicrystalline polymers, owing to its exceptional chain length, restricted entanglement dynamics, and unparalleled capacity to develop highly oriented crystalline architectures under tailored processing routes. Despite the extensive proliferation of studies spanning gel-spinning, melt-processing, surface modification, additive manufacturing, and application-specific microstructural engineering, the field remains fragmented, with limited integration of mechanistic insights across disparate sub-domains. This review consolidates advances in rheological control, phase-transition engineering, crystallographic manipulation, interfacial modification, and property evolution under diverse thermal–mechanical histories. By correlating molecular mobility, lamellar assembly, fibrillar development, and defect generation with macroscopic performance in biomedical, structural, filtration, protective, and electrochemical systems, the review provides a unifying framework that interrogates how UHMWPE’s non-Gaussian chain statistics, constrained relaxation modes, and processing-induced mesophases collectively govern functional performance. The work further delineates emergent methodologies including topological disentanglement strategies, nanoscale templating, reactive compatibilization, and multi-physics simulations that are poised to redefine UHMWPE’s processability and application bandwidth. The resulting synthesis offers researchers a comprehensive, mechanistically anchored, and forward-looking understanding of UHMWPE’s structure–processing–property interdependence.
