Key Findings in This Report

• Dendritic MXene@CNT heterostructures serve as multifunctional catalysts, nucleators, and interface enhancers for polyesters. • Biorenewable MCP nanocomposites achieve ultrahigh mechanical strength (~101 MPa), stiffness (~3.1 GPa), and toughness (~130 MJ m−3). • MCP exhibits exceptional reprocessability (90% strength retention after 5 cycles), gas barrier (O2 0.0187 barrer), and UV resistance (blocks 85% UVA). • The catalysis-interfacial strengthening integration strategy enables high-performance bio-based polyester materials for plastic replacement.
