Plasticizer effect on mechanical properties of β
The mechanical properties (elastic modulus, EM; tensile strength, TS and % elongation, %E) of β-lactoglobulin (β-Lg) films plasticized with different plasticizers were determined. Six plasticizer types were studied over a range of concentrations. Propylene-glycol-plasticized β-Lg films were the most brittle, with mechanical properties
Plasticizer effect on mechanical properties of ??-lactalbumin
The effect of different plasticizers (glycerol, polyethylene glycol, sorbitol) on the mechanical, water vapor barrier, optical, and moisture sorption properties of hydroxypropyl methylcellulose
Plasticizer effects on physical-mechanical properties
These results showed these four plasticizers are capable to plasticizing Soluplus as indicated by the glass transition temperature lowering, tensile strength, and Young's modulus while increasing the percent elongation and film toughness. Among the plasticizers tested, polyethylene glycol 6 showed greatest changed in the mechanical properties
Effects of plasticizer type and concentration on rheological
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. Based on the analysis of rheologica
Plasticized kafirin-based films: analysis of thermal, barrier
The change in glass transition temperature (Tg) of the films was analysed using differential scanning calorimetry. The thermal stability of films was ascertained by TGA. The measurement of breaking strength and elongation at break helped in studying the effect of plasticizers on the mechanical properties of the films.
- Can -lactoglobulin films be plasticized with different plasticizers?
- The addition of combined plasticizers (GLY and PEG) can modify the mechanical properties and water vapor permeability . β-Lactoglobulin films were plasticized with different plasticizers (PG, GLY, sorbitol, PEG 200, PEG 400 and sucrose) aiming at improving the mechanical properties.
- Does plasticizer type affect the equilibrium moisture content of films?
- Plasticizer type did not significantly affect the equilibrium moisture content of films. Sucrose added films were the most fragile at low RH, while GLY films were the most hygroscopic. However, at RH of 76–90%, sucrose films showed similar resistance compared to other plasticized films.
- Do plasticizers affect alginate-based films?
- Some reviews on the effect of plasticizers are about improving the flexibility of the most common biopolymers such as PLA and starch [10, 11], but there is no dedicated article focusing the effect of plasticizers on alginate-based films, in particular.
- How does the type of plasticizer affect biopolymer properties?
- The type of plasticizer can strongly affect the barrier properties, water uptake, and mechanical properties of the biopolymer.
- Do polyols affect mechanical and surface properties of chitosan films?
- The effect of polyols such as GLY, EG, PEG and PG on mechanical and surface properties of chitosan films was evaluated considering the plasticizer volatility , since it may influence film properties and stability during application and storage, i.e. the less volatile the plasticizer, the better it is for use.
- What is a good plasticizer for biopolymer films?
- 2. Polyols such as glycerol, ethylene glycol, diethylene glycol, tri-ethylene glycol, polyethylene glycol, xylitol, sorbitol, and mannitol are considered effective plasticizers to improve the properties of biopolymer films.
