AI Technical Summary
The intrinsic incompatibility between existing nylon and epoxy resin leads to uncontrollable phase separation. The large size and uneven distribution of the nylon dispersed phase affect the stability of the toughening effect. The introduction of nylon often comes at the cost of sacrificing modulus and strength, making it difficult to achieve a synergistic improvement in toughening and reinforcement. Traditional nylon/epoxy composites have limited functions and lack intelligent characteristics such as self-healing, high barrier properties, and recyclability.
A continuous phase epoxy resin composition with anisotropic morphological gradient is adopted, which includes a continuous covalently cross-linked epoxy resin matrix network and contains a first spatial enrichment domain, an intermediate phase morphological domain and a second spatial enrichment domain that exhibit a continuous transition in the vertical thickness direction. A dynamic cross-linked network is constructed by modifying MXene nanosheets and nylon 6 oligomers, and a multi-layer gradient distribution is formed by combining gradient curing process.
It achieves ultra-high load-bearing mechanical strength, excellent fracture toughness, long-term high-barrier corrosion protection, intelligent self-healing, and full life-cycle chemical recyclability. It eliminates the hidden danger of interlayer shear peeling failure, improves the macroscopic tensile strength and yield stiffness of the material, and achieves efficient interface self-healing after mechanical damage.
