  • What are the advantages of bioplasticizers?
  • The proposed bioplasticizers show remarkable miscibility with PHB and low leaching. The bioplasticizers also show a remarkable plasticization effect in terms of reducing the glass transition and melting temperatures (17 °C and 8 °C, respectively), which are comparable with the performance of the best commercially available green plasticizers.
  • How stable is a plasticizer at 200 °C?
  • From this test, it is possible to appreciate that the plasticizer is stable up to 200 °C without any appreciable signal due to evaporation transition, in accordance with the low volatility described previously. Interestingly, we have noticed that the plasticizer presents its own Tg of approx. −49 °C evaluated with a scanning rate of 20 °C·min –1.
  • What is the volatility of a plasticizer?
  • The volatility of the plasticizer has been evaluated by placing the plasticized formulations in an oven in isothermal conditions. Samples of around 50 mg were stored at 70 °C for 24 h. Volatility is expressed in terms of weight loss by eq 2, where W1 and W2 are the initial and final weights after the test, respectively.
  • Is GT a bioplasticizer?
  • The GT bioplasticizer is also demonstrated to be susceptible to enzymatic (cutinase) degradation, demonstrating a potentially available upcycling. All presented results make it possible to define the herein-presented molecule as a bioplasticizer with a high plasticization efficiency toward different macromolecules.
  • Can Gly and La be used as a bioplasticizer?
  • The herein-presented work shows a valorization approach to convert GLY and LA in a versatile bioplasticizer for different polymers, representing a potential alternative to the existing “green plasticizers”. In particular, GT was obtained by solvent-free and mild-condition esterification of LA with GLY.
  • Is PHBV a promising biopolymer?
  • Furthermore, PHB and a related copolymer poly (3-hydroxybutyrate- co -3-hydroxyvalerate) (PHBV) were studied as promising and emerging biopolymers characterized by challenging mechanical properties and molten processability that therefore require plasticizers to be improved.
