“…However, at the same time, because the CSDG content was too high, agglomeration occurred, resulting in voids in the composite matrix, making the structure loose. This resulted in a decrease in the composite film resistance to water vapor permeability [53,54]. Figure 11 clearly depicts changes in the permeation path of water vapor or oxygen in PLA/CSDG and MPLA/CSDG composites.…”

Adding natural biomass to poly(lactic acid) (PLA) as a reinforcing filler is a way to change the properties of PLA. This paper is about preparing PLA/biomass composites by physically melting and blending Chinese Spirits distiller’s grains (CSDG) biomass and PLA to optimize the composite performance. Composites of modified PLA (MPLA) with varying amounts of CSDG were also prepared by the melt-mixing method, and unmodified PLA/CSDG composites were used as a control group for comparative analysis. The functional groups of MPLA enhanced the compatibility between the polymer substrate and CSDG. The composite water vapor/oxygen barrier and mechanical properties were studied. It was found that the barrier and mechanical properties of MPLA/CSDG composites were significantly improved. SEM was adopted to examine the tensile section structure of the composites, and the compatibility between the filler and the matrix was analyzed. An appropriate amount of CSDG had a better dispersibility in the matrix, and it further improved the interfacial bonding force, which in turn improved the composite mechanical properties. X-ray diffraction, thermogravimetric analysis, and differential scanning calorimetry were conducted to determine the crystalline properties and to analyze the stability of the composites. It was found that the CSDG content had a significant effect on the crystallinity. Barrier and biodegradation mechanisms were also discussed.

“…It is worth noting that the XRD crystallinity trend is almost identical to the DSC crystallinity trend, and similarly, the values of G-ZnO concentration in the nanocomposites at 0.2% and 0.3% are also very close, further demonstrating the reliability of both crystallinity values. However, at G-ZnO concentrations of 0.4%, the intensity of the peak decreased significantly due to agglomeration within the crystal gaps, which caused unbalanced crystal growth and a decrease in crystallinity [45]. The characteristic diffraction peaks of PPS/G-ZnO nanocomposites shifted to the left, except for the two peaks that shifted to the right when the G-ZnO concentration was 0.3%.…”

Nano zinc oxide-decorated graphene (G-ZnO) was blended with polyphenylene sulfide (PPS) to improve its tensile, thermal, crystalline, and barrier properties. The properties of neat PPS and PPS/G-ZnO nanocomposites were characterized and compared using various tests, including tensile tests, scanning electron microscopy, X-ray diffraction, differential scanning calorimetry, thermogravimetric analysis, evaluation of Escherichia coli inhibition, and barrier performance. The results demonstrated that G-ZnO played a crucial role in heterogeneous nucleation and reinforcement. When the concentration of G-ZnO was 0.3%, the tensile strength, elongation at break, thermostability, crystallinity, and water vapor permeability coefficients (WVPC) approached their maximum values, and the microscopic morphology changed from the original brittle fracture to a relatively tough fracture. In addition, when G-ZnO was added to PPS at a ratio of 0.3%, the tensile strength, elongation at break, and WVPC of PPS were increased by 129%, 150%, and 283%, respectively, compared to pure PPS. G-ZnO endowed the nanocomposites with antibacterial properties. The improvement in barrier performance can be attributed to three reasons: (1) the presence of G-ZnO extended the penetration path of molecules; (2) the coordination and hydrogen bonds between PPS polymer matrix and G-ZnO nanofiller narrowed the H2O transmission path; and (3) due to its more hydrophobic surface, water molecules were less likely to enter the interior of PPS/G-ZnO nanocomposites. This study provides valuable insights for developing high-performance PPS-based nanocomposites for various applications.

“…When the concentration of CG ≥ 0.3%, the CG agglomeration appeared within the crystal gaps due to the high concentration of CG. Therefore, the crystal growth is not balanced, resulting in a decrease in crystallinity [43]. In addition, with the adding of CG in PPS, the two characteristic diffraction peaks shifted to the left, which may be due to an increase of distances in the interplanar spacing and lattice parameter [44]..…”

Carboxylated graphene (CG) with functional group was blended with polyphenylene sul de (PPS), CG enhanced the tensile, thermal properties, crystallinity and barrier performance of PPS. Through tensile test, scanning electron microscopy, X-ray diffraction, differential scanning calorimetry, thermogravimetric analysis, evaluation of S. aureus inhibition, and barrier performance, the properties of pure PPS and PPS/CG nanocomposites were characterized and compared. The results showed that CG acted a role in heterogeneous nucleation and reinforcement. When the concentration of CG was 0.2%, the tensile strength, elongation at break, thermostability, crystallinity and water vapor permeability coe cients (WVPC) approached maximum values, and the microscopic morphology changed from the original brittle fracture to a relatively tough fracture. Compared with pure PPS, when CG was added to PPS at 0.2%, the tensile strength, elongation at break and WVPC of PPS were signi cantly increased by 23.9%, 17.2%, and 18.3% respectively. This improvement in barrier performance might be attributed to two reasons: (1) The presence of CG extended the penetration path of molecules; (2) The hydrogen bond from PPS matrix and CG nano ller, so as to narrow the H 2 O transmission path. CG endows nanocomposites with antibacterial properties.
