Effects of plasticizer type and concentration on rheological
Abstract 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.
Effect of Polyolic Plasticizers on Rheological and Thermal
The effects of plasticizers on thermal properties of resin were investigated by DSC at -100 to 150°C. No crystallization and melting peaks related to zein resin and plasticizers were...
Influence of External Plasticization on Rheological and
At thermoplastic foam production via melt technologies rheological and thermal properties are key factors for the generation of high quality products. Therefore, the influence of external plasticization on rheological and thermal properties of cellulose acetate (CA) was investigated. Different types of plasticizers were used for this study.
Fatty acid modified zein films: Effect of fatty acid chain
While these petrochemical -based conventional plastics display appealing material properties and hence their popularity, they pose a significant threat to the environment due to their use in enormous amounts, lack of degradation, and accumulations in landfills that usually spill into the environment (Kakadellis and Rosetto, 2025, Ojogbo et al.,
Extensional Flow Properties of Externally Plasticized
Rheotens tests were conducted to investigate the influence of plasticizer content on elongational flow properties of cellulose acetate (CA). Triethyl citrate (TEC) was used as plasticizer. Melt...
- 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 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.
- 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.
- Does plasticizer type affect optical properties of bioactive edible films?
- The effects of plasticizers type and concentration on the optical properties of bioactive edible films were shown in Table 3. The result indicated plasticizer improved the opacity of chitosan/zein blend films, and the opacity of films was increased significantly (p < 0.05) with an increase of plasticizer concentration.
- Does plasticizer concentration affect permeability of chitosan/Zein films?
- The permeability of films increased significantly with the increase of plasticizer concentration, but the C/ Z -P film (plasticized chitosan/zein film with PEG-400) had better barrier performance compared with the other two. The C/ Z -P film had better mechanical properties and light transmission.
- Why is rheology important in polymerization?
- Rheological behaviors of film-forming solution could affect the thickness, uniformity and mechanical properties of film. The study of the rheology could illuminate the polymerization reaction so as to produce edible films with excellent performance.
