基于剪切增稠液的防切割织物的研究进展OA

Shear thickening fluids(STFs,which display a reversible transition from a fluid-like to a solid-like state under high stress,have emerged as a promising strategy for improving the cut resistance of flexible textiles.This unique rheological response enables fabrics to maintain softness and comfort during normal use while providing enhanced protection under sudden impact or penetration.Over the past two decades,research on STF-based protective materials has grown rapidly,driven by increasing demands for lightweight,wearable,and reliable safety solutions.In this context,STFs have been studied from the perspectives of formulation design,rheological characteristics,and textile integration,establishing a theoretical and experimental foundation for their application in advanced protective fabrics.This review provides a systematic summary of these developments,aiming to clarify the relationship between STF microstructure and macroscopic properties,and to highlight the significance of STF in the field of cut-resistant textiles. The integration of STF into textiles has been realized through several principal approaches,including impregnation,surface coating,and microencapsulation.Each method has distinct advantages and limitations impregnation allows STF to penetrate into the inter-fiber spaces and reinforce the internal structure of fabrics coating produces a protective barrier that responds rapidly to external force;and microencapsulation provides stability and environmental adaptability by preventing fluid leakage.In addition to processing techniques,the mechanisms by which STFs improve fabric performance have also been extensively analyzed.Key reinforcement effects include the formation of a temporary rigid network under dynamic loading,increased friction and cohesion between fibers,and enhanced interfacial interlocking between STF particles and textile structures.Together,these effects contribute to the effective dissipation of energy,delayed fiber failure,and overall improvement in resistance to cutting and penetration.Comparative studies across woven,knitted,and nonwoven fabrics demonstrate that STF exhibits versatile reinforcing capabilities,adapting to the structural characteristics of different textile systems and broadening the scope of its applications. Despite significant progress,several challenges remain before STF-treated textiles can be widely applied in practice.The interfacial stability between STF and fibers requires improvement to ensure long-term durability during repeated use,bending,and washing.The rheological properties of STFs are sensitive to environmental factors such as temperature and humidity,which can alter their protective efficiency.At the same time,large-scale processing and industrial scalability remain technical bottlenecks,particularly in achieving uniform STF distribution and reproducible performance.Moreover,the absence of standardized evaluation methods for dynamic cut resistance complicates direct comparison of results and slows the establishment of clear performance benchmarks.Looking forward,future research should focus on improving STF-fiber compatibility through surface modification and chemical functionalization,developing durable and adaptable composite systems,and optimizing fabrication processes to balance protective performance with comfort and wearability.In addition,the establishment of unified testing protocols and evaluation standards will be crucial to accelerating the translation of STF-based technologies from laboratory studies to industrial practice.With continued innovation in formulation,processing,and evaluation,STF composites are expected to play a central role in the next generation of high-performance protective textiles,providing effective solutions for occupational safety,industrial applications,and personal protection.
