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.
Effect of Plasticizer on the Morphology and Foaming
As an environment-friendly polymer, polyvinyl alcohol (PVA) foams have attracted increasing attention due to their excellent thermal insulation and cushioning properties. However, the main drawback of PVA is its difficulty in melt processing (due to strong inter-/intrahydrogen bonds) and to control the cell morphology. To overcome the processing limits and realize the control of cell
Comparison of the Effect of Plasticizers on PHBV—and
The synergistic effect of plasticizer and clay was also evident in our mechanical analysis of the compounds; TEC exhibited promising results as an alternative eco-friendly plasticizer compared with DOP, mainly when combined with OMt.
Effects of microplastic particles and leaching additive on
Since this is obligatory for risk assessment, we analyzed the chronic effects of flexible polyvinylchloride (PVC), a widely used polymer, containing the plasticizer diisononylphthalate (DiNP) on morphology and life history of the freshwater crustacean Daphnia magna and compared these effects with the effects of rigid PVC, lacking DiNP, as well
The Effect of Plasticizers on the Properties of Polyvinyl
The plasticizers not only reduced the degree of crystallinity in the films, but also lowered the crystalline melting temperatures probably by introducing defects into the crystal lattice.
- How do plasticizers affect crystalline morphology?
- Crystalline and morphology structures were also changed differently according to the type of plasticizers. The crystalline degree was increased by all these plasticizers with an order: glycerol > PEG > PG. PEG had the best plasticizing effect in decreasing the tensile strength, modulus and increasing the elongation of pure HPMC and blending films.
- Do plasticizers affect the structural and physical properties of curdlan edible films?
- Conclusions This study investigated the effects of various plasticizers—glycerol (GLY), ethylene glycol (EG), propylene glycol (PRO), xylitol (XY), sorbitol (SOR), and polyethylene glycol (PEG)—on the structural and physical properties of curdlan (CL) edible films.
- Which plasticizer has the best morphology?
- These structural changes led to a more uniform distribution of amorphous chain segments and a decrease in glass transition temperatures. Among the tested plasticizers, GLY exhibited the highest compatibility with CL, resulting in the smoothest surface morphology and delivering the most effective plasticizing effect.
- Does EG plasticizer affect the morphology of PVA?
- It was demonstrated that EG plasticizer exhibited good plasticizing effect, which decreased the melting point and widened the processing window of PVA. Moreover, the plasticizer could affect the melt strength and crystallization of samples, thus, affecting the foaming process and the cell morphology.
- How does plasticizer content affect cell morphology in polymer foaming?
- With the increase of plasticizer content, the cell size of the foam increased from 9.30 μm (10 phr) to 12.75 μm (30 phr), and the expansion ratio increased from 2.33 (10 phr) to 3.36 (30 phr). This work has reference significance for the study of the regulation of cell morphology in the subsequent polymer foaming process.
- Do plasticizers affect the self-similar structure of glycerol blending films?
- The self-similar structure was significantly affected by the type of plasticizers. PEG decreased the compactness of the self-similar structure of all samples, while PG presented an opposite effect on pure HPS and the blending films. For glycerol plasticized samples, lamellar structure with a repeat distance of 15.7 nm was presented.
