Summary: Carbon nanotubes (CNTs) reinforced polymeric nanocomposite has great potential for lightweight and multifunctional materials. However, achieving strong interfacial interaction and high orientation of CNTs is challenging due to their tendency to agglomerate. In this study, an ultrasonic assisted stretching strategy was proposed to enhance interfacial interaction and orientation of CNTs in composites. Under optimal ultrasonic processing conditions, the strength, modulus, toughness, and electrical conductivity of aligned nanocomposites were significantly improved.

CNT/epoxy resin (EP) composite strips with different orientations and densities were prepared by infiltrating EP into CNTS, stretching, and pressing. Tensile strength of composite strips prepared under stretching and pressing was nine times higher than that of pristine CNTSs due to rearrangement of CNTs and proper resin infiltration.

Summary: Multi-scale rigid-soft material coating was used to enhance the interfacial shear strength (IFSS) of carbon fibers (CFs). Chitosan (CS) and carbon nanotubes (CNTs) were grafted onto the CFs surface, increasing the roughness and activity of the CFs surface and improving mechanical interlocking and chemical bonding. The modified CFs composites showed a 186.9% increase in IFSS (123.65 MPa) and a 26.79% increase in tensile strength compared to desized fibers. This strategy provides a valuable reference for obtaining high-performance CFs composites.

Summary: This study demonstrates a new approach to overcoming the dual challenges of uniform dispersion of CNTs and lack of interaction with the matrix during the fabrication of composites, using an active dispersant Py-PEI. The presence of pyrene groups in Py-PEI successfully prevents the re-aggregation of dispersed CNTs through pi-pi stacking, while the amine groups establish covalent bonds with epoxy to enhance load transfer efficiency between CNTs and the matrix. Systematic characterization of both fabricated BP and BP-reinforced nanocomposites shows significantly improved stability of CNT dispersion in water and enhanced mechanical performance of the composites.
