Effects of Nano Alumina and Plasticizers on Morphology, Ionic
Nano alumina (Al 2 O 3) was used as filler, and dioxyphthalate (DOP) and polyethylene glycol (PEG) applied as plasticizers. Various concentrations of lithium salts, nano alumina and plasticizers (5, 10, 15 and 20 wt%) were studied. The morphology, ionic conductivity, thermal and mechanical properties of the SPE were also examined.

Plasticizers were added to improve the flexibility and homogeneity of the wheat starch-based bioplastic. Control film exhibited high tensile strength (38.7 MPa) with low elongation (1.9%). However, films plasticized with 35% sorbitol showed the highest elongation, which was 60.7% at break.

- 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).
- How is plasticization achieved in polymer morphology?
- Plasticization is achieved by incorporating a plasticizer into polymer matrix, copolymerization, or blending. Among those, adding plasticizer is the most common and simplest way to modify polymer morphology. Plasticizer can lessen the intermolecular forces along the polymer chains. As a result, free volume was increased and T g was lowered.
- How do plasticizers affect polymer morphology?
- Among those, adding plasticizer is the simplest and most commonly used way to modify polymer morphology. Plasticizers can weaken intermolecular forces along the polymer chains, thus increasing free volume and lowering the glass transition temperature. For this reason, polymers with plasticizers have improved ductility.
- Do different glycerol concentrations affect G-plasticized films?
- Subsequently, G-plasticized films exhibited better barrier and environmental properties than other starch-based biofilms. Overall, the present study showed that different glycerol concentrations affected the physical, structural, mechanical, thermal, and barrier properties of G-plasticized films.
- Do plasticizer concentrations affect hydrophilicity of biopolymers?
- MC of all plasticized AS biopolymers enhanced significantly with enhancing plasticizer concentrations from 15 to 45%, as shown in Fig. 7. In general, the hydrophilicity of starch-based films was enhanced with an increase in the concentration of plasticizers.
- Do plasticizers increase hydrophilicity of hydrocolloid films?
- In general, the hydrophilicity of starch-based films was enhanced with an increase in the concentration of plasticizers. Consequently, several studies reported that the addition of plasticizers caused an increment in the moisture content of hydrocolloid films 56, 71.
