Summary: The PLA/PBAT blend is a biodegradable material that can potentially replace petroleum-based polymeric products. However, the poor interfacial adhesion between PLA and PBAT limits their compatibility. This review provides an overview of the current research on the manufacturability, compatibilization, biodegradation, radiation processing, and cellulose nanocrystal reinforcement of PBAT and PLA polymer blends.

Summary: A reactive compatibilizer was used to modify a PLA/PBAT blend foam, resulting in PLA blend foams with improved impact strength. The interfacial adhesion and cell size were found to strongly affect the impact strength of the foams. Enhancing interfacial adhesion and reducing cell size resulted in significantly improved impact properties. This study provides a feasible and practical strategy for preparing highly toughened and fully biodegradable PLA materials.

Summary: The objective of this study was to investigate multiphase systems based on blends of polylactic acid (PLA) and polyamide 11 (PA11), ranging from blends to multilayers. By using reactive extrusion, PLA/PA11 blends compatibilized with a multifunctionalized epoxide, Joncryl, were obtained. The thermal, morphological, rheological, and mechanical behaviors of these materials were studied. The results revealed that the addition of Joncryl as a compatibilizer significantly reduced particle size and interfacial tension, resulting in ductile behavior in the tensile properties. Furthermore, the effects of interdiffusion and diffuse interphase formation on structure, rheology, and mechanics of compatible multilayered systems fabricated with forced-assembly multilayer coextrusion were investigated based on these findings. This study contributes to a deeper understanding of the interfacial properties, such as rheological, mechanical, and morphological behaviors, and their control in multilayer polymers produced by coextrusion, enabling their use in advanced applications.

Summary: This study investigated the combined effect of algae loading and in-house produced coupling agent on the thermal and mechanical properties of polylactic acid (PLA) prepared by melt compounding. The use of PLA-grafted with maleic anhydride (MA) as a coupling agent significantly improved the interfacial adhesion between PLA and algae. The results showed that the thermal stability and tensile properties of PLA depended on the grafting level of MA and the concentrations of algae. Therefore, a combination of low concentrations of algae (5 and 10 wt%) and high grafting levels of PLA-g-MA can greatly enhance the thermal stability of PLA.

Summary: Poly(lactic acid) (PLA) is a widely produced biobased, biodegradable and biocompatible polyester. Although it shares similarities with petroleum-based polymers, its high brittleness and low toughness limit its utilization, prompting the blending with other biobased and biodegradable polymers. By incorporating appropriate additives and solid nanoparticles, the toughness and ductility of PLA can be improved, enhancing its mechanical performance, thermal stability and gas/vapor barrier properties.

Summary: The present study focuses on the preparation of cottonseed protein/poly(ε-caprolactone) (CP/PCL) blend films by melt blending and hot pressing. The addition of PCL in CP/PCL blends results in the formation of a co-continuous phase, leading to significant improvement in the mechanical properties of the films. Furthermore, the incorporation of a compatibilizing agent enhances the chemical interaction between the polymer phases, resulting in improved dispersion and increased physical compatibility between the protein and polymer chains.

Summary: In this study, super toughened PLA-based blends were successfully prepared by melt blending PLA with EVA and compatibilizing with E-MA-GMA. The addition of E-MA-GMA promoted phase adhesion and increased interface thickness, resulting in a super-toughened blend with incomplete fracture behavior during impact tests. The maximum impact strength of 77.6 kJ/m(2) was achieved with 12 wt% E-MA-GMA in the ternary blend, showing a 27.7 times improvement over neat PLA. Rheological and micromorphology analysis demonstrated enhanced viscosity and reduced crystallinity in the ternary blends.

Summary: Poly(butylene sebacate-co-terephthalate) (PBSeT) is a biodegradable flexible polymer that can be melt blended with other biodegradable polymers. In this study, PBSeT polyester was synthesized and blended with poly(lactic acid) (PLA) using PLA-grafted maleic anhydride (PLA-g-MAH) compatibilizers. The addition of PLA-g-MAH improved the interfacial adhesion, mechanical properties, and miscibility of the PLA/PBSeT blends. It also enhanced the thermal stability of the blends and facilitated hydrolytic degradation.

Summary: This study investigates the impact of homogeneously modified (HM) and Janus silica nanoparticles on the thermostimulative shape memory effect in high-density polyethylene/poly(ethylene terephthalate) blend-based polymer nanocomposites. The results demonstrate that the physical/mechanical characteristics of the polymer/polymer interface play a crucial role in defining the shape memory effect. The Janus nanoparticles are synthesized through a two-step desymmetrization process, while a single-step modification procedure is used for homogenous modification. The samples containing Janus nanoparticles exhibit the strongest shape memory effect.

The study revealed that the methylene blue loading had different impacts on the hydrogels, with higher release rates observed in simulated gastric fluid. The release kinetics of methylene blue in the hydrogels followed a pseudo-second-order mechanism.

Summary: This study aimed to develop porous films based on polylactic acid (PLA) for sensors and absorbers, with improved properties through surface functionalization. Polycaprolactone (PCL) and graphite nanoplatelets (GNP) were added to enhance the flexibility and conductivity of the polymer matrix. The phase inversion method successfully controlled the aggregation of PCL and GNP in the films. Aminolysis reaction and functionalization significantly improved the stability and dye retention capacity of the films. The optimized PLA/PCL-GNP films showed potential as electrodes for voltammetric determination and as absorbers for model dyes.

Summary: Studies have shown that incorporating ZnO nanoparticles into biopolymer-based films can improve their properties, but results vary. This study conducted a meta-analysis to evaluate the effects of different parameters of ZnO nanoparticles on the characteristics of bionanocomposite films. The results demonstrated that adding commercially, physically, or chemically synthesized ZnO nanoparticles with a size of 1-100 nm, rod morphology, and concentration level <8.4% significantly improved the water vapor permeability, tensile strength, and elongation of the films. This study highlights the importance of using ZnO nanoparticles with appropriate parameters to enhance film properties and prolong the shelf life of food products.

Summary: Edible films (EF) are biodegradable alternatives to traditional food packaging. The properties of EF are affected by the raw materials used. This meta-analysis study compared the properties of fish gelatin films and mammalian gelatin films, finding that fish gelatin films had lower tensile strength, elastic modulus, water vapor permeability, and transparency. The study also discussed the effects of film fabrication methods and gelatin concentration on the properties of the films.
