  • Can Plasticizers improve the mechanical properties of a polymer?
  • The mechanical properties of the polymer that may be improved by the addition of plasticizers include decreased the tensile strength and Young’s modulus and increased in percent elongation, toughness and resistance to cracking, etc. ( 17 – 20 ).
  • Does adding PEG as a plasticizer affect thermal and mechanical properties?
  • The films were analyzed using differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA), and dynamic rheological analysis. The results indicate that the addition of PEG as a plasticizer affects the thermal and mechanical properties of the PLA/PEG blend films.
  • Can low molecular weight PEG be used as a plasticizer for PLA?
  • This study investigates the impact of using low molecular weight PEG (Mn = 400 g/mol) as a plasticizer for PLA. The study examines the effect of plasticization on the crystallization behavior, thermal, dynamic mechanical, and rheological properties of PLA.
  • Which plasticizer is the most effective?
  • All four plasticizers effectively decreased the Tg, tensile strength, and Young’s modulus and increased the percent elongation and toughness of the film. Among the plasticizers tested, PEG-6 is the most efficient plasticizer in changing the mechanical properties of the films.
  • How does plasticizer affect polymer chain mobility?
  • At the highest plasticizer level (25% w / w ), Tgs of TEC, PPG, and Gly are observed between 30°C and 31°C while the Tg of PEG-6 was observed at 14°C. This significant reduction in Tg values with addition of PEG-6 at 25% is an indication of the plasticizer effect that results in significant increase in polymer chain mobility.
  • Can Peg be used as a plasticizer?
  • The results indicate that the addition of PEG as a plasticizer affects the thermal and mechanical properties of the PLA/PEG blend films. The study found that the glass transition and cold crystallization temperatures decreased with increasing PEG content up to 20 wt%, while the crystallinity and crystallization rate increased.
