“…The cause trailing the poor bonding is the hydrophobic attribute of filler which causes the pull-outs and cracks. 51 Comparatively, the 5% alkali treated composite film (Figure 3(c)) shows continuous assessment of filler which demonstrate excellent interfacial adhesion between MOSF and PVA matrix. Similarly, the 5% acid treated composite film (Figure 3(c)) is showing a homogeneous distribution with better filler-matrix bonding.…”

The present work focuses on surface functionalization, characterization, biodegradability and barrier properties of MOSF as a practicable reinforcement in PVA matrix. Film-forming dispersions at different concentrations of alkali and acid treatments were casted at room temperature. The effect of surface modifications on the developed film’s compositional, physical, mechanical, biodegradability and barrier properties were analyzed. Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), Scanning electron microscopy (SEM) and Atomic force microscopy (AFM) were used to describe the functional composition, formation and surface morphology of the film. The 5% acid treated film significantly increases the tensile strength (33.69 MPa) and flexural strength (56.612 MPa), which was close to the frequently used LDPE and HDPE package films. Composite films were moisture absorptive but simultaneously capable to maintain uniformity and composition upon modifications. Lower water vapor permeability (1.42 × 10−10gs−1 m−1 Pa−1), eminent biodegradability proved the suitability of composite film for various packaging applications.

“…Incorporating Pinhão husk powder as a source of fibers to the films provided changes in the mechanical properties, reducing the ELO and increasing the TS of the films (Figure S1), a behavior similar to that reported in films with material added as a structure reinforcer. 8,47 Generally, the best values for these properties were obtained in the PF6 and GF6 formulations, which contain 0.4% Pinhão husk powder. This increase may have been due to the presence of intermolecular interactions between the film components, which could be the main reason for the significant increase in ELO and TS.…”

In this study, the use of Pinhão husk as a source of reinforcement material for development of edible films, where the Pinhão seed flour and bovine gelatin were used as matrices for the films. Mechanical properties, water vapor permeability, solubility and opacity, microstructure, and thermal degradation characterized the films produced. The films presented homogeneous and cohesive structures. Pinhão husk content positively affected film properties by increasing tensile strength (TS) and decreasing water vapor permeability (WVP), with Pinhão flour film formulations (5.0% Pinhão flour, 1.2% glycerol, and 0.4% Pinhão husk) and gelatin (5.0% gelatin, 2.0% glycerol, and 0.4% Pinhão husk) those that presented the best results (5.06 MPa for TS and 0.14 g.mm/kPa.h.m2 for WVP) and (3.88 MPa for TS and 0.28 g.mm/kPa.h.m2 for WVP), respectively The thermal degradation study revealed that the films are stable at temperatures below 150°C, losing only free water and volatile compounds of low molecular weight. Pinhão husk can reinforce films, making them suitable as biodegradable and edible packaging materials for eco‐friendly food products. This contributes to the circular economy, preserves biodiversity, and reduces plastic waste, offering promising sustainable packaging solutions.

Composite industries use natural fibre as a sustainable resource to improve the sustainability and eco-friendliness of polymer composites. The characterization of alkali-treated Moringa oleifera fruit husk fibres (AMOFHFs) reinforced in unsaturated polyester resin matrix with varying weight percent of nano-sized silicon carbide (SiC) particles as filler material is presented in this paper. The AMOFHFs reinforced composite (AMOFHFC) specimens contain 20 wt.% AMOFHFs and nano-sized SiC particles ranging from 1 to 5 wt.% in 1 wt.% steps. The effect of wt.% variation in nano-sized SiC particles on the mechanical, morphological, tribological and water absorption behaviour of AMOFHFC specimens was thoroughly investigated. According to the findings, the AMOFHFC specimen with 4 wt.% nano-sized SiC particles as filler material has the best mechanical, tribological and water absorption properties. The hardness, tensile, flexural and impact strength of the AMOFHFC specimen with 4 wt.% nano-sized SiC particles improved by 14.86%, 23.11%, 9.6% and 23.22% respectively compared to the composite specimen without SiC nanoparticles as filler material. Similarly, the AMOFHFC specimen with 4 wt.% nano-sized SiC particles exhibited a lesser weight loss of 96.7% compared to the composite specimen without SiC nanoparticles as filler material during the Pin-on-disk experimentation which showcases its superior tribological characteristics. Furthermore, SEM images of fractured tensile AMOFHFC specimens aided in understanding the bonding nature of the AMOFHFs, SiC nanoparticles and unsaturated polyester resin matrix in the composite specimens. The findings above led us to the conclusion that AMOFHFCs with acceptable hydrophobic nature are best suited for light weight automotive and structural applications.
