Comparison of the Effect of Plasticizers on PHBV—and
The synergistic effect of plasticizer and clay was also evident in our mechanical analysis of the compounds; TEC exhibited promising results as an alternative eco-friendly plasticizer compared with DOP, mainly when combined with OMt.
Effects of Nano Alumina and Plasticizers on Morphology, Ionic
Nano alumina (Al 2 O 3) was used as filler, and dioxyphthalate (DOP) and polyethylene glycol (PEG) applied as plasticizers. Various concentrations of lithium salts, nano alumina and plasticizers (5, 10, 15 and 20 wt%) were studied. The morphology, ionic conductivity, thermal and mechanical properties of the SPE were also examined.
Long- and short-term stability of plasticized poly(lactic
Addition of plasticizers (regardless of plasticizer type) to the PLA, even at lower loading levels (5 wt%), decreased the yield strength and modulus of PLA. It is known that plasticizers result in a decrease in the intermolecular forces between the polymer chains, which lowers the polymer chain cohesion . Yield strength and the modulus of PLA
Effect of plasticizer on physical and mechanical
Based on this mechanical properties result, plasticizer content was fixed at 30% where elongation at break and tensile strength are in balance conditions. ... Preparation and Characterization of...

- How is plasticization achieved in polymer morphology?
- Plasticization is achieved by incorporating a plasticizer into polymer matrix, copolymerization, or blending. Among those, adding plasticizer is the most common and simplest way to modify polymer morphology. Plasticizer can lessen the intermolecular forces along the polymer chains. As a result, free volume was increased and T g was lowered.
- How do plasticizers affect polymer morphology?
- Among those, adding plasticizer is the simplest and most commonly used way to modify polymer morphology. Plasticizers can weaken intermolecular forces along the polymer chains, thus increasing free volume and lowering the glass transition temperature. For this reason, polymers with plasticizers have improved ductility.
- Do plasticizers affect spherulitic morphology of PHB?
- Polarized optical microscopy (POM) was used to evaluate the effect of the addition of plasticizers on the spherulitic morphology of PHB. The samples were heated to 210 °C and cooled to 60 °C (isothermal crystallization temperature) to promote the samples’ crystallization.
- Does plasticizer concentration affect mechanical properties of PHB?
- The effect of the plasticizers’ concentration on the mechanical properties of PHB, i.e., elastic modulus (E), maximum tensile strength (σ), and elongation at break (ε), is shown in Figure 9. Neat PHB is a material with high rigidity due to its crystallinity ; it has a high elastic modulus and low elongation at break.
- Do plasticizers affect the properties of films based on corn starch?
- Similar results were found in studies by (Alves et al. 2015) who evaluated the effect of inserting CNCs and gelatin in films plasticized with corn starch, and (Hazrati et al. 2021) who studied the effect of plasticizers on the properties of films based on Dioscorea hispida starch.
- Which oligomers are used to evaluate the plasticizing effect on PHB matrix?
- In this work, two linear-chain polyester oligomers—plasticizer 1 and plasticizer 2 (P1 and P2, respectively)—were used to evaluate the plasticizing effect on the PHB matrix at concentrations up to 30 wt%. The plasticizers are distinguished by the C-O/C=O ratio: approx. 0.923 and 2.226 for P1 and P2, respectively.
