Effect of Plasticizer on the Morphology and Foaming
Moreover, the plasticizer could affect the melt strength and crystallization of samples, thus, affecting the foaming process and the cell morphology. The foaming effect of PVA foams was obviously
Effect of Plasticizer on the Morphology and Foaming
It was demonstrated that EG plasticizer exhibited good plasticizing effect, which decreased the melting point and widened the processing window of PVA. Moreover, the plasticizer could affect the melt strength and crystallization of samples, thus, affecting the foaming process and the cell morphology.

Influence of plasticizer on ionic conductivity of PVC-PBMA polymer
The reason for this could be due to the anti-plasticizing effect exhibited by plasticizers up to 60 wt% of ethylene carbonate . It is evident that as the concentration of the plasticizer content increases the conductivity increases, i.e., the higher ionic conductivity of 4.990 × 10 4 S cm 1 is observed for film consisting of 75% of EC.
The illustration of preparation and effect of plasticizer on the
These results are related to the work of Yin et al. [41], who studied the effect of ethylene glycol plasticizer on the morphology of PVOH foam. It could affect the foaming process and the cell
- Do plasticizers affect the structural and physical properties of curdlan edible films?
- Conclusions This study investigated the effects of various plasticizers—glycerol (GLY), ethylene glycol (EG), propylene glycol (PRO), xylitol (XY), sorbitol (SOR), and polyethylene glycol (PEG)—on the structural and physical properties of curdlan (CL) edible films.
- Which plasticizer has the best morphology?
- These structural changes led to a more uniform distribution of amorphous chain segments and a decrease in glass transition temperatures. Among the tested plasticizers, GLY exhibited the highest compatibility with CL, resulting in the smoothest surface morphology and delivering the most effective plasticizing effect.
- How do plasticizer effects affect physical-mechanical properties of solvent cast films?

- Does EG plasticizer affect the morphology of PVA?
- It was demonstrated that EG plasticizer exhibited good plasticizing effect, which decreased the melting point and widened the processing window of PVA. Moreover, the plasticizer could affect the melt strength and crystallization of samples, thus, affecting the foaming process and the cell morphology.
- How does plasticizer content affect cell morphology in polymer foaming?
- With the increase of plasticizer content, the cell size of the foam increased from 9.30 μm (10 phr) to 12.75 μm (30 phr), and the expansion ratio increased from 2.33 (10 phr) to 3.36 (30 phr). This work has reference significance for the study of the regulation of cell morphology in the subsequent polymer foaming process.
- What are the effects of plasticizer in film production?
- For instance, inadequate or excessive use of plasticizer in films may lead to improper film formation, partial or full phase separation eventually leading to poor or unacceptable quality. In addition, disintegration time of ODFs is important, as it may significantly affect drug release and thereafter absorption and bioavailability.
