THE EFFECTS of PLASTICIZERS ON CRYSTALLINITY, PERMEABILITY, and
The effects of plasticizers (polyethylene glycols [PEG] 400, 1,450, 8,000 and 20,000, glycerol [G] and propylene glycol [PG]), 30% dry basis, on the physical properties of methylcellulose (MC) films
THE EFFECTS of PLASTICIZERS ON CRYSTALLINITY, PERMEABILITY, and
All plasticizers significantly (α= 0.05) increased oxygen (O2P) and water vapor permeabilities (WVP) of the films as compared to that of unplasticized MC, with PEG 400 having the greatest effect on O2P and G having the greatest effect on WVP.

Effect of plasticizers and fatty acids on mechanical and permeability
The effect of processing on the performance of the obtained films is also evaluated applying the solution casting and the heat-pressing methodologies. Overall it is shown that glycerol is more effective as plasticizer resulting in as high as 70% strain, compared to 26% strain obtained after 30 wt.% oleic acid's addition.
- Do plasticizers affect the crystallinity index?
- X-ray Diffraction (XRD) To study the effect of different plasticizers in various concentrations on the crystallinity index, an XRD test was conducted. Figure 6 shows the crystalline peaks of plasticized wheat starch films. It shows that plasticized films have a lower crystallinity than the control film.
- Does plasticizer affect structural properties of polymer-salt matrix?
- The combined effect of filler and plasticizer on polymer-salt matrix can lead to better electrical, electrochemical as well as thermal properties. 3. Conclusions Effect of inclusion of plasticizers on structural properties of polymer electrolytes is discussed with aid of literature reports available.
- Why does a plasticized polymer have a high water saturation?
- The hydrophilic nature of a plasticized film decreases with the addition of plasticizer content, which means higher water content in the film leads to increased water saturation. Hydroxyl groups in starch and plasticizer particles are the reason for the high water absorption of the plasticized polymer .
- Do plasticizers enhance lithium ion transport in PEO-based solid polymer electrolytes?
- Enhanced lithium ion transport in PEO-based solid polymer electrolytes employing a novel class of plasticizers Ionic conductivity studies in composite solid polymer electrolytes based on methylmethacrylate Effect of plasticizer and lithium salt concentration in PMMA-based composite polymer electrolytes Int. J. Electrochem.
- Do plasticizers affect the performance of starch films?
- J. Tarique et al. reported that different plasticizer concentrations had an impact on the physical, structural, mechanical, thermal and barrier characteristics of plasticized films; the inclusion of plasticizers improves the performance of starch films as a whole. Similar findings were recently reported by other researchers .
- How do plasticizers affect film mechanical properties?
- Plasticizers affect film mechanical properties as well as barrier properties. Fatty acids such as lauric, miristic, palmitic, stearic, and oleic acids have been shown to reduce the WVP of hydroxy propyl methyl cellulose (HPMC) composite films (Jiménez et al., 2010).
