“…Compression modulus of PHBV film increased by 25% with the addition of GO nanosheets [ 65 ]. Incorporation of 0.7 wt% graphene nanoplatelets in the PHB matrix with uniform dispersion resulted in the enhancement of tensile stress from 7.5 to 12.2 MPa [ 89 ]. Addition of mechanically stable GO into the polymeric matrix bestowed the flexibility of the PHBV based Fe 3 O 4 /GO-g-PHBV composite enhancing tensile strength and elongation at break [ 90 ].…”

“…SPN have been shown to be able to accelerate the biodegradation rate of PHB nanofiber scaffold with weight loss percentage increasing from 14.4% to 30.4% after degradation for 30 days in enzyme solution [ 66 ]. It has been shown that addition of graphene nanoplatelets into PHB matrix led to decrease in the rate of degradation due to the non-degradable nature of graphene [ 89 ]. Incorporation of 20% curcumin increased the biodegradation rate of PHB/MWCNT electrospun nanofibers to about 35% of mass loss after 4 weeks compared to 6% mass loss of neat PHB nanofibers [ 81 ].…”

This review is focused on hybrid polyhydroxyalkanoate-based (PHA) biomaterials with improved physico-mechanical, chemical, and piezoelectric properties and controlled biodegradation rate for applications in bone, cartilage, nerve and skin tissue engineering. PHAs are polyesters produced by a wide range of bacteria under unbalanced growth conditions. They are biodegradable, biocompatible, and piezoelectric polymers, which make them very attractive biomaterials for various biomedical applications. As naturally derived materials, PHAs have been used for multiple cell and tissue engineering applications; however, their widespread biomedical applications are limited due to their lack of toughness, elasticity, hydrophilicity and bioactivity. The chemical structure of PHAs allows them to combine with other polymers or inorganic materials to form hybrid composites with improved structural and functional properties. Their type (films, fibers, and 3D printed scaffolds) and properties can be tailored with fabrication methods and materials used as fillers. Here, we are aiming to fill in a gap in literature, revealing an up-to-date overview of ongoing research strategies that make use of PHAs as versatile and prospective biomaterials. In this work, a systematic and detailed review of works investigating PHA-based hybrid materials with tailored properties and performance for use in tissue engineering applications is carried out. A literature survey revealed that PHA-based composites have better performance for use in tissue regeneration applications than pure PHA.

“…A hybrid co-filler made with SWCNT and GO fillers with a loading of only 0.4% into PLA films decreased the oxygen transmission rate by 67% and diminished the transmission of ultraviolet-visible light by 30%. Manikandan et al [ 8 ] proved that the use of polyhydroxybutyrate biocomposite containing 0.7 wt% GNPs had improved water, oxygen, and UV barrier properties and was also able to promote a fourfold increase of potato chips and milk products shelf life. The improvement in gas and water barrier of graphene-based biocomposites is explained by the introduction of impermeable graphene-based nanofillers with large surface area which restricts the motions of the biopolymer chains, and the creation of a tortuous pathway into the film matrix that complicates gas molecules diffusion.…”

This review aims to showcase the current use of graphene derivatives, graphene-based nanomaterials in particular, in biopolymer-based composites for food packaging applications. A brief introduction regarding the valuable attributes of available and emergent bioplastic materials is made so that their contributions to the packaging field can be understood. Furthermore, their drawbacks are also disclosed to highlight the benefits that graphene derivatives can bring to bio-based formulations, from physicochemical to mechanical, barrier, and functional properties as antioxidant activity or electrical conductivity. The reported improvements in biopolymer-based composites carried out by graphene derivatives in the last three years are discussed, pointing to their potential for innovative food packaging applications such as electrically conductive food packaging.

“…Polyhydroxybutyrate (PHB) and its copolymer, poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) are the two most representative natural polyesters of microbial origin belonging to the PHA family. Although PHB shows rigidity similar to PP [ 9 ], its sensorial results on the food were positive. The nanocomposites based on PHB containing graphene nanoplatelets (Gr-NPs) in a concentration of 0–1.3 wt% prepared by a casting solution [ 9 ] and silver in a single step approach [ 10 ], in addition to blends with PLA [ 11 ], have been investigated for the design of food packaging.…”

Electrospun Nanosystems Based on PHBV and ZnO for Ecological Food Packaging

The electrospun nanosystems containing poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) and 1 wt% Fe doped ZnO nanoparticles (NPs) (with the content of dopant in the range of 0–1 wt% Fe) deposited onto polylactic acid (PLA) film were prepared for food packaging application. They were investigated by scanning electron microscopy (SEM), energy dispersive X-ray (EDX), Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), antimicrobial analysis, and X-ray photoelectron spectrometry (XPS) techniques. Migration studies conducted in acetic acid 3% (wt/wt) and ethanol 10% (v/v) food simulants as well as by the use of treated ashes with 3% HNO3 solution reveal that the migration of Zn and Fe falls into the specific limits imposed by the legislation in force. Results indicated that the PLA/PHBV/ZnO:Fex electrospun nanosystems exhibit excellent antibacterial activity against the Pseudomonas aeruginosa (ATCC-27853) due to the generation of a larger amount of perhydroxyl (˙OOH) radicals as assessed using electron paramagnetic resonance (EPR) spectroscopy coupled with a spin trapping method.
