  • Do plasticizers affect the thermal stability of polymer-protein intermolecular interactions?
  • It is clear that plasticizers affect the polymer-protein intermolecular interactions and decrease the thermal stability of the films [36, 43]. On the other hand, in Fig. 6 b, the peak intensities of the DTG curves of PEG plasticized films are generally lower than PLAST-0. This indicates to decreasing weight loss rate.
  • Are PVA/CA/Peg/Sor containing films more flexible than UN-plasticized films?
  • The effects of plasticizer type and concentration on the structural, mechanical, thermal, barrier properties of the films were evaluated. This work demonstrated that PVA/CA/PEG and PVA/CA/SOR form compatible blends via hydrogen bonding interactions. The PEG and SOR containing films are more flexible than un-plasticized film.
  • Do two plasticizers affect PVA film properties?
  • This study investigates the synergistic effect of two plasticizers on the PVA film properties. The PVA/DEA/H 2 O films exhibit a significant enhancement and toughening effects when 3% H 2 O is introduced at 5% and 10% DEA contents.
  • How does plasticizer affect permeability of biodegradable films?
  • The addition of PEG and SOR to the PVA/CA film affected the permeability differently. The addition of PEG decreased WVP of PLAST-0 the film by 14%, while the addition of SOR increased by 90% in the same amount. The increasing of WVP of biodegradable films with the addition of plasticizer has been reported in different studies [22, 35, 37].
  • How does plasticizer content affect elongation and fracture strength?
  • As the plasticizer content increases, the Young's modulus and fracture strength of the films decrease, with an increase in the elongation at break. The film no longer exhibits the yield phenomenon at elevated levels of plasticizer content. The PVA film demonstrates a similar phenomenon with varying contents of GLY (Fig. 1 b).
  • Does plasticizer increase tensile elongation of casted PVA film?
  • In this study, the effects of individual plasticizer, namely, DEA, GLY and H 2 O, on the mechanical properties were first studied. The results indicated that adding plasticizer increases the tensile elongation of the casted PVA film, with the highest value obtained by adding H 2 O, followed by DEA and GLY.
