“…Considering its exceptional mechanical properties, protective characteristics and resistance to corrosion, polyurea demonstrates significant potential for use in safeguarding port terminals against underwater explosions. Polyurea coatings can be employed to provide an additional protective layer on various surfaces within port terminal facilities including floors, walls and pipelines [57,[137][138][139]. Additionally, polyurea coatings possess exceptional impact resistance, corrosion resistance and flame-retardant properties that enable them to efficiently absorb and dissipate energy from blasts, effectively mitigating damages and injuries caused by explosions.…”

Polyurea has gained significant attention in recent years as a functional polymer material, specifically regarding blast and impact protection. The molecular structure of polyurea is characterized by the rapid reaction between isocyanate and the terminal amine component, and forms an elastomeric copolymer that enhances substrate protection against blast impact and fragmentation penetration. At the nanoscale, a phase-separated microstructure emerges, with dispersed hard segment microregions within a continuous matrix of soft segments. This unique microstructure contributes to the remarkable mechanical properties of polyurea. To maximize these properties, it is crucial to analyze the molecular structure and explore methods like formulation optimization and the incorporation of reinforcing materials or fibers. Current research efforts in polyurea applications for protective purposes primarily concentrate on construction, infrastructure, military, transportation and industrial products and facilities. Future research directions should encompass deliberate formulation design and modification, systematic exploration of factors influencing protective performance across various applications and the integration of numerical simulations and experiments to reveal the protective mechanisms of polyurea. This paper provides an extensive literature review that specifically examines the utilization of polyurea for blast and impact protection. It encompasses discussions on material optimization, protective mechanisms and its applications in blast and impact protection.
