“…The incorporation of cellulose ller slightly reduced the contact angle to 86.8° due to the cellulose's polar and hydrophilic nature (Andresen et al 2006). A similar effect was noted by Tsou et al (Tsou et al 2022), who introduced distiller's grains into a poly(ethylene terephthalate) matrix, which for 25% ller loading, reduced the contact angle from 91.3° to 87.0°. However, modi cation of applied cellulose ller with diisocyanates noticeably increased contact angle to 93.5°, 97.7°, and 92.4°, respectively, for HDI, MDI, and TDI, which was attributed to the reduced polarity of modi ed llers reported in previous work (Hejna et al 2021c).…”

Sustainable polymer composites are progressively under development in a technological paradigm shift from "just use more and more" to "convert into value-added products". The bio-based blends based on Mater-Bi bio-plastic (A) and poly(ε-caprolactone) (B), at a weight ratio of 70:30 (A:B) were developed, followed by the addition of UFC100 cellulose (C) filler to yield 70/30 (w/w) (A:B)/C sustainable biocomposites. The effects of chemical modification of C with three diisocyanates, i.e., hexamethylene diisocyanate (HDI), methylene bisphenyl isocyanate (MDI), or toluene diisocyanate (TDI) on the surface properties of biocomposites was evaluated by water contact angle and surface roughness detected by atomic force microscopy (AFM). Biocomposites containing C modified with HDI, MDI, or TDI revealed contact angle values of 93.5°, 97.7°, and 92.4°, respectively, compared to 88.5° for reference blend, indicating enlarged hydrophobicity window. This action was further approved by increased fracture surface roughness and miscibility detected by microscopic observation (scanning electron microscopy (SEM) and AFM) and in-depth oscillatory rheological evaluation. Correspondingly, thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) analyses showed more residue and higher melting temperatures for biocomposites, more promisingly with MDI and TDI modifiers. In conclusion, either incorporation or diisocyanate modification of C affects both surface and bulk properties.

“…As presented in Figure 4, the incorporation of unmodified cellulose filler resulted in a slight drop in the composite's WCA from 88.5 • to 86.8 • , indicating a shift towards the more hydrophilic character. Similar effects have been noted by Laaziz et al [53] after the introduction of 15 wt% argan nut shell particles into poly(lactic acid) (drop from 79.4 • for unfilled PLA to 73.0 • ) by Tsou et al [54], who incorporated 25 wt% of distiller's grains into a poly(ethylene terephthalate) (drop from 91.3 • to 87.0 • ). Such an effect can be limited by appropriately modifying the applied fillers aimed at masking their hydrophilicity.…”

Despite their popularity and multiplicity of applications, wood–polymer composites (WPCs) still have to overcome particular issues related to their processing and properties. The main aspect is the compatibility with plant-based materials which affects the overall performance of the material. It can be enhanced by strengthening the interfacial adhesion resulting from physical and/or chemical interactions between the matrix and filler, which requires introducing a compatibilizer or a proper modification of one or both phases. Herein, the impact of cellulose filler modifications with varying contents (1–10 wt%) of hexamethylene diisocyanate (HDI) on the compatibility of Mater-Bi/poly(ε-caprolactone) (PCL)-based biocomposites was evaluated. An analysis of surface wettability revealed that the filler modification reduced the hydrophilicity gap between phases, suggesting compatibility enhancement. It was later confirmed via microscopic observation (scanning electron microscopy (SEM) and atomic force microscopy (AFM)), which pointed to the finer dispersion of modified particles and enhanced quality of the interface. The rheological analysis confirmed increased system homogeneity by the reduction in complex viscosity. In contrast, thermogravimetric analysis (TGA) indicated the efficient modification of filler and the presence of the chemical interactions at the interface by the shift of thermal decomposition onset and the changes in the degradation course.

In this paper, ZnO-decorated graphene (ZnO-graphene) was added to poly(butylene adipate-co-terephthalate) (PBAT) and maleic anhydride-grafted poly(butylene adipate-co-terephthalate) (PBAT-g-MAH) to prepare antibacterial nanocomposites through melt blending. The effect of different amounts of ZnO-graphene on the properties of the nanocomposite materials was discussed. The results of Fourier transform infrared (FTIR) analysis showed that PBAT-g-MAH could form coordination reaction and hydrogen bond with ZnO-graphene, and this synergistically enhanced the tensile properties of the nanocomposites. With the introduction of functional groups, the mechanical properties of PBAT-g-MAH/ZnO-graphene nanocomposites were significantly improved. Compared with pure PBAT, the nanocomposites showed that the maximum tensile strength, yield strength, and elongation at break increased by 20.58, 17.04, and 7.51%, respectively. This work revealed for the first time through X-ray diffraction tests the probable mechanism of dispersion or compatibility in the nanocomposites. Water absorption properties and water contact angle data proved that the introduction of MAH, along with the optimal amount of nanofillers, could greatly improve the tightness of internal and surface structures of the nanocomposites. Relative to PBAT, the use of PBAT-g-MAH/ZnO-graphene containing 0.6% nanofillers significantly improved the water vapor and oxygen barrier efficiencies by 152.8 and 273.5%, respectively. It was shown from the results of antibacterial evaluation that ZnO-graphene could impart PBAT and PBAT-g-MAH with excellent antibacterial activity. Compared with pure PBAT, the nanocomposite films had better mechanical and barrier properties. Both PBAT and PBAT-g-MAH nanocomposites could decompose naturally in soil, indicating that they were environmentally friendly and would have great application prospect in the fields of packaging and medical industries.
