“…Aramid fabric showed broadened peaks between 10 and 30°with apparent (110), ( 200) and (004) facets on 19, 23, and 28°, respectively. Such an XRD pattern of aramid is consistent with previously reported studies, 41,42 suggesting that the pronounced feature in this region is mainly inuenced by the aramid XRD background. Despite the broad background, (001), (100), (101), ( 102) and (110) planes of SnS 2 on 15, 28, 32, 42 and 50°, respectively, could still be identied.…”

“…Allyl and benzyl modified ANFs improved the mechanical properties of polystyrene composite films including toughness, Young's modulus and yield strength. 27 Blending PP with PET offers some advantages such as PET enhancing the stiffness of PP at high temperatures while PP facilitating crystallization of PET by heterogeneous nucleation. 28 Overall, PET has the tendency of improving the properties of PP, but the immiscibility of both polymers is a major drawback.…”

Polypropylene (PP) and poly(ethylene terephthalate) (PET) are plastics commonly used for packaging because of their excellent barrier and mechanical properties. The properties of these plastics are often diminished after mechanical recycling, inevitably causing down‐cycling. This problem is exacerbated when different kinds of polymers mix. Aramid nanofibers have the potential to improve the mechanical properties of polymers due to their excellent mechanical properties but their poor dispersion in polymers is a challenge. Grafting polymers onto nanofibers can help address this challenge. In this work, different loading levels (1%, 2%, and 5%) of polymer grafted aramid nanofibers (ANFs) are blended with waste PP/PET (90/10), simulating a PP waste stream containing traces of PET contaminants. Scanning electronic microscopy, rheology, and differential scanning calorimetry results show the affinity of PP functionalized aramid nanofibers (PP_ANF) towards the PP matrix. At 1 wt% of the nanofiber, the size of the PET droplets in the PP matrix of the PP_ANF blend range from 0.2 to 2.0 μm while that of unmodified ANF and PET_ANF blends are in the range of 0.1–6.2 and 0.5–7.4 μm, respectively. In summary, polymer grafted ANFs have the tendency of improving properties of its like polymers due to similarity in the grafting polymer and the polymer matrix.

“…As is well known that polystyrene (PS) is one of the most common plastics in the modern chemical industry, and expanded polystyrene (EPS) foam is widely used in building insulation, packaging materials, sound insulation materials, decorative materials, and other fields (Xing et al, 2013;Sun and Lawrence, 2017;Huang et al, 2018;Ito et al, 2018;Wang et al, 2018;Peng et al, 2020;Hamann et al, 2021;Cao et al, 2022;Liu and Peng, 2022). With the increasing competition of PS and EPS markets at home and abroad, requirements for the performance and function of PS and EPS are put forward in the above-mentioned fields.…”

A series of colorized and magnetic polystyrene/Fe3O4 (PS/Fe3O4) composite beads with millimeter size are successfully synthesized by introducing hydrophobic Fe3O4via in situ suspension polymerization of styrene for the first time. Effects of the hydrophobic Fe3O4 content, stirring speed, and surfactant dosage on the macromorphology and particle size of PS/Fe3O4 beads are systematically investigated to realize the controllable synthesis. Moreover, three kinds of hydrophobic pigments are also employed to synthesize colorized polystyrene, which demonstrates the versatility, simplicity, and wide applicability of the proposed method. Scanning electron microscopy (SEM) and element mapping (EM) images demonstrated that the hydrophobic Fe3O4 is well dispersed in the polystyrene matrix. Thermogravimetric analysis (TGA) shows that the resultant PS/Fe3O4 beads possess a better thermal stability than neat PS. PS/Fe3O4 beads have a promising application in the fields of colorized extruded PS board, colorized expanded PS foam particle, and board.
