Summary: The preparation of nanocomposites with controllable structure is important, and the preparation of ultrashort composite nanotubes with core-shell structure from long nanotubes is challenging. Researchers have successfully prepared ultrashort core-shell composite nanotubes with the outer layer of SiO2 or TiO2 and the inner layer of sulfonated PDVB by mixing their long composite nanotubes with polymer resin and shearing at a high strength with a twin-screw extruder.

Summary: In this study, expandable graphite was encapsulated by poly-siloxane to prepare a flame retardant polypropylene composite. The composite achieved a high flame retardancy rating even at a low loading, and showed significantly reduced heat release during combustion. The burning behavior was investigated through experiments and numerical simulations, and the structure of the residual char was analyzed through chemical analysis and microscopy.

Summary: BNNS/epoxy resin composite films with high out-of-plane thermal conductivity were successfully prepared by optimizing the magnetic field strength. Magnetically responsive BNNSs were prepared by loading Fe3O4 nanoparticles, and well-aligned BNNS/EP composites were achieved by controlling the magnetic field intensity and direction. The well-oriented BNNSs resulted in significantly improved thermal conductivity.

Summary: Research on polymer composites filled with thermal conductive filler is important due to the heat dissipation demands in the development of miniaturized and highly integrated electronic devices. Graphene, with its high thermal conductivity, tends to agglomerate in a matrix due to strong van der Waals interactions. However, a synergistic effect of hybrid fillers consisting of graphene and other fillers with different size and shape can prevent this agglomeration and achieve a high thermal conductivity at low filler loading.

Summary: This study investigates the effects of intermixing duo-fiber reinforcement on the tensile and impact properties of epoxy composites. Three different methods of reinforcement were used: flax-kenaf alternate yarn polymer composite (FKAYPC), flax-kenaf twisted yarn polymer composite (FKTYPC), and flax-kenaf mixed fiber yarn polymer composite (FKMFPC). The composites were prepared with 40% wt. fraction of reinforcement, with 20% wt. for each fiber. The experimental findings showed that the alternate yarn polymer composite exhibited the highest tensile strength of 76 MPa, followed by the mixed fiber yarn composite with 63 MPa, and the twisted yarn composite with the lowest magnitude of 50 MPa. The impact strengths were equal for the alternate and twisted yarn composites, both measuring 20 kJ/m(2), while the mixed yarn composite had a lower impact strength of 15 kJ/m(2).
