Highly entangled networks，as a novel design strategy for soft materials，effectively address the contradiction among strength，toughness，and fatigue resistance in traditional crosslinked materials by regulating the topological entanglement structure of molecular chains. This paper systematically reviews five strategies to construct highly entangled networks： high-concentration monomer polymerization，post-crosslinking of highly entangled chains，dual-network synergistic high entanglement of dual networks，macromolecular crosslinking high entanglement，and nanocomposite high entanglement. The molecular design principles，structural characteristics，and performance advantages of each strategy are analysed. In the field of functional applications，this review highlights the innovative applications of highly entangled materials in wear-resistant coatings，durable devices，adhesives，and intelligent actuators，demonstrating the excellent mechanical properties and unique functional characteristics endowed by highly entangled networks. Moreover，the challenges and future directions of highly entangled soft materials are discussed，emphasizing that multi-scale simulation technology，bionic adaptive design，and green manufacturing processes will be important research directions in this field. This review provides systematic theoretical guidance and technical reference for the design and application of functional soft materials with highly entangled networks.
