The effects of plasticizer on the mechanical and electrical
As described above, PLA became softer with an increase in the amount of plasticizer. At 298 K, dielectric breakdown strength (E B) was about 5 MV/cm, irrespective of the presence of the plasticizer; the plasticizer showed almost no effect on E B. At 353 K, however, E B had a tendency to increase with an increase in the amount of plasticizer.
Effect of plasticizer on electrical conductivity and cell
The plasticizer substantially reduces the brittleness of many polymers because the addition of even small quantities of the plasticizer markedly reduces the glass transition temperature, T g, of the polymer. The electrical conductivity of a polymer electrolyte increases on the addition of plasticizer.
Effect of different plasticizer on structural and electrical
3.1 X-ray diffraction. The X-ray diffraction analysis is a useful tool to determine the structure and crystallization of the polymer matrices. In order to investigate the effect of plasticizers concentration in the PVC–PEMA–LiClO 4 system, XRD analysis has been performed, and their respective diffraction patterns of PVC, PEMA, LiClO 4 and their complexes PVC(5)–PEMA(20)–LiClO 4 (8
Plasticizer
The effect of plasticizers on elastic modulus is dependent on both temperature and plasticizer concentration. Below a certain concentration, referred to as the crossover concentration, a plasticizer can increase the modulus of a material. The material's glass transition temperature will decrease, however, at all concentrations.

- Does plasticizer increase DC conductivity of PEC electrolyte?
- From the DSC and BES results, it was revealed that the addition of plasticizer decreased the glass transition temperature and increased the dc conductivity (σdc) of the PEC electrolyte.
- How does plasticizer affect surface conductivity?
- Here the surface conductivity decreases as the concentration of plasticizer increases. The effect of the plasticizer is pronounced in the case of low loading of CB (5 wt%), beacuse the plasticizer disrupts the carbon black network formed inside the PP matrix, and CB particles are dispersed with wider gaps.
- Does plasticizer reduce dielectric constant in pp/CB composites?
- The plasticizer has reduced the dielectric constant when it is added to PP/CB composites. The effect is noticeable, especially when the CB loading is high (15 wt% CB), and the plasticizer effect is negligible when the CB loading is low (5 wt% CB).
- Do plasticizers increase decoupling and fragility m?
- From the results of the Walden plot and fragility analysis, it was expected that the degree of decoupling ε and fragility m would increase with the addition of plasticizer because these plasticizers weaken the interactions between the PEC chains and Li ions in the electrolyte.
- Does emimtfsi plasticize PEC electrolyte?
- The BES results also revealed that the plasticizer increased the segmental motion of PEC and improved σdc, and the plasticizing effect of EMImTFSI on the PEC electrolyte was larger than that of glycerol.
- Do plasticizers weaken interactions between PEC chains and Li ions?
- From the results of the Walden plot and fragility analysis, it was revealed that the degree of decoupling and the value of fragility increase by the addition of plasticizer, and these plasticizers weaken interactions between PEC chains and Li ions in the electrolyte.
