Fully biobased and biodegradable materials have attracted a growing interest in the food packaging sector as they can help to reduce negative impact of fossil-based plastics on environment. Moreover, addition functionalities these by introducing active molecules has become an essential requirement create modern able extend food's shelf-life while informing consumer about quality freshness. In this study, we present innovative bioplastic formulation for based poly(hydroxybutyrate-co-valerate)...
In the last two decades, use of phthalates has been restricted worldwide due to their well-known toxicity. Nonetheless, are still widely used for versatility, high plasticization effect, low cost, and lack valuable alternatives. This study presents fully bio-based versatile glycerol trilevulinate plasticizer (GT) that was obtained by valorization levulinic acid. The mild-conditions solvent-free esterification synthesize GT optimized investigating product Fourier transform infrared NMR...
Abstract Polylactic acid (PLA) is a widely used biopolymer, but its brittleness and limited biodegradability hinder application as standalone material. To enhance properties, PLA can be compounded with plasticizers, ideally nontoxic from sustainable sources. While phthalates remain the predominant their known harmful effects have led to development of bio‐based alternatives like glycerol trilevulinate (GT). This study investigates plasticizing effect GT on amorphous (aPLA) semi‐crystalline...
A new class of biobased plasticizers is herein proposed as a replacement the currently used additives. The molecules were synthesized by selective protecting-group-free route, which was developed in order to produce valuable asymmetrical ketal–diester derivatives from renewable levulinic acid, overcoming typical drawbacks these types reactions. Five with different side chains successfully obtained and fully characterized means NMR FT-IR spectroscopies. These additives then tested poly(vinyl...
In this study, we report the fabrication of two different three-dimensional (3D) architectures regenerated silk (RS) and poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) with embedded functionalities. 3D printed cylinders an internal layer PHBV external calcium ions (Ca++) or potassium nitrate (KNO3) modified RS were designed to control radial shrinkage, water uptake compression strength. Such then used as sutureless thermoresponsive clips, measuring bursting resistance once applied on...
PHB has been engineered by incorporating different levulinic acid-based bioplasticizers, which enhance flexibility and thermal processability of the neat biopolymer, while retaining excellent biocompatibility biodegradability.
The gas separation performance of biopolymers is still scarcely characterized, mostly because their poor thermomechanical properties and high crystallinity which associated to low permeability. In this work we characterize the transport in a poly(hydroxybutyrate-co-hydroxyvalerate) (PHBV) random copolymer, that has relatively good mechanical properties, combined with renewable origin, biodegradability biocompatibility. study also compared several solvents for membrane casting, different...
The combination of biopolymers and bioactive inorganic particles for bone tissue regeneration has been investigated in the last decades. However, several studies report discordant results on specific synergistic effect compounds. A comparative study porous scaffolds obtained by most promising is herein reported. Specifically, have fabricated Thermally Induced Phase Separation method using poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV), poly(lactic acid) (PLA), poly(caprolactone) (PCL)...
In the near future, polyhydroxybutyrate (PHB) may become a valuable widespread alternative to conventional fossil-based commodity plastics, if drawbacks related its melt-processability and mechanical properties are overcome. this work, PHB disadvantages have been mitigated by compounding with glycerol trilevulinate (GT) bioplasticizer. The additive synthesis has studied optimized, starting from fully bio-based reagents that wastes other productions. GT shown remarkable plasticizing effect,...

In this study, regenerated silk (RS) obtained from Bombyx Mori cocoons is compounded with carboxyl-functionalized carbon nanotubes (f-CNTs) in an aqueous environment for the fabrication of functional bio-adhesives. Molecular interactions between RS and carboxyl groups CNTs result structural increase β-sheet formation, obtaining a resistant adhesive suitable wet biological substrate. Moreover, functionalization promotes their dispersion RS, thus enabling production films controlled electrical...
