Effect of Plasticizer on Structural and Electrical Properties
crystallite size (L) calculated from Scherre’s equation for 100 peak of PEO for different concentration of plasticizer exhibits that the crystallite size decreases on increasing plasticizer concentration. These observations suggest an enhancement in the degree of disorder and amorphocity in the polymeric films on plasticization [19]. Figure 2.
Effect of plasticizer on structural and electrical properties
The solid polymer electrolyte films based on polyethylene oxide, NaClO4 with dodecyl amine modified montmorillonite as filler, and polyethylene glycol as plasticizer were prepared by a tape casting method. The effect of plasticization on structural, microstructural, and electrical properties of the materials has been investigated. A systematic change in the structural and microstructural
Effects of plasticizer type and concentration on rheological, physico
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.
- Does glycerol plasticizer affect elongation of sodium caseinate film?
- Audic and Chaufer reported similar effects of excess amount of triethanolamine and glycerol plasticizers on the elongation value of sodium caseinate film and also Siew and coworkers reported similar results for sodium caseinate films [14, 16]. The effects of SOR and PEG on the elongation of PVA/CA film
- How does plasticizer affect permeability of biodegradable films?
- The addition of PEG and SOR to the PVA/CA film affected the permeability differently. The addition of PEG decreased WVP of PLAST-0 the film by 14%, while the addition of SOR increased by 90% in the same amount. The increasing of WVP of biodegradable films with the addition of plasticizer has been reported in different studies [22, 35, 37].
- Do plasticizers increase the tensile strength of PVA/CA film?
- The addition of plasticizers decreased the tensile strength while the increased elongation at break value of PVA/CA film. The maximum tensile strength was observed in 10% PEG addition as 37.5 MPa. On the other hand, maximum elongation at break value was observed in 15% SOR at 369% that was higher than the un-plasticized film about 58%.
- Do plasticizers increase elongation at break value of PVA/CA film?
- On the other hand, elongation at break value of PVA/CA film (234.8%) increased considerably with the addition of both plasticizers (Fig. 4). This is the plasticization effect of SOR and PEG that increased the chain mobility and finally the stretchability and flexibility of the films.
- Does plasticizer loading rate affect elongation?
- According to Fig. 4, the maximum elongation was observed for 15% plasticizer loading rate as 369% for SOR and 326% for PEG. Above this loading rate, elongation value decreased, but it was still higher than PLAST-0 film. This behavior related to excess content of plasticizers.
- Do plasticizers affect the thermal stability of polymer-protein intermolecular interactions?
- It is clear that plasticizers affect the polymer-protein intermolecular interactions and decrease the thermal stability of the films [36, 43]. On the other hand, in Fig. 6 b, the peak intensities of the DTG curves of PEG plasticized films are generally lower than PLAST-0. This indicates to decreasing weight loss rate.
