  • How does plasticizer affect the rheological properties of film-forming solution?
  • Plasticizer influenced the rheological properties of film-forming solution. Plasticizer was efficient for the improvement of properties of blend film. The chitosan/zein film with PEG-400 exhibited superior properties.
  • How does plasticizer affect rheological behavior and solid loading?
  • The type and content of plasticizer had substantial effects on the rheological behavior and solid loading, leading to differences in macro / micro structure and property of the green body and sintered part. The shear shinning and thixotropy behaviors were characterized for both PEG-400 and DBP cases.
  • Does plasticizer type affect chitosan/Zein film rheological and structural properties?
  • The chitosan/zein film with PEG-400 exhibited superior properties. The purpose of this study was to evaluate the effect of plasticizer type (glycerol, PEG-400, and sorbitol) and concentration (0%, 15%, 30% and 45%, w /w dry polymer weight) on rheological and physico-mechanical and structural properties of chitosan/zein blend film.
  • How does plasticizer content affect flexural strength?
  • In the case of the same plasticizer, the concentration of monomer decreases as the plasticizer content increases, which means the decrease of the flexural strength of the green body with increasing plasticizer content. This trend can be observed in the DBP group.
  • Which polymer has a plasticizing effect?
  • Plasticizers were dissolved in the polymer and dispersed evenly, increasing the free volume of the polymer, separating chains from each other and facilitating chain movement [21, 30, 36, 37]. The results showed that glycerol, PEG-400 and sorbitol had obvious plasticizing effect. Fig. 2.
  • Do plasticizers increase entanglement between polymers?
  • By observing the tan δ curve and the tan δ = 1 (G′ = G″) transversal line, we found that the plasticizers could make the system be gelatinous characteristics at lower frequency, which might be due to the fact that the addition of plasticizers increased the entanglement between polymers and enhanced the hydrogen bond between the molecules . 3.2.
