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.
Comparison of the Effect of Plasticizers on PHBV—and
Materials. Poly(hydroxybutyrate-co-hydroxyvalerate) was supplied by . (ENMAT Y 1000) with a valerate content of 3.4 mol% (estimated via 1 H NMR solution (CDCl 3) spectroscopy) and a solubility parameter of 20.6 MPa 1/2.
Long- and short-term stability of plasticized poly(lactic
Addition of plasticizers (regardless of plasticizer type) to the PLA, even at lower loading levels (5 wt%), decreased the yield strength and modulus of PLA. It is known that plasticizers result in a decrease in the intermolecular forces between the polymer chains, which lowers the polymer chain cohesion . Yield strength and the modulus of PLA
The Effect of Plasticizers on the Properties of Polyvinyl
The effect of water-soluble plasticizers viz propylene glycol (PG), glycerol and polyethylene glycol 600 (PEG) on the morphology and water resistance of polyvinyl alcohol (PVA) films was investigated.
Effect of plasticizer on physical and mechanical
Based on this mechanical properties result, plasticizer content was fixed at 30% where elongation at break and tensile strength are in balance conditions. ... Preparation and Characterization of...
- How is plasticization achieved in polymer morphology?
- Plasticization is achieved by incorporating a plasticizer into polymer matrix, copolymerization, or blending. Among those, adding plasticizer is the most common and simplest way to modify polymer morphology. Plasticizer can lessen the intermolecular forces along the polymer chains. As a result, free volume was increased and T g was lowered.
- 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.
- 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.
- 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.
- 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.
- What are the effects of plasticizer in film production?
- For instance, inadequate or excessive use of plasticizer in films may lead to improper film formation, partial or full phase separation eventually leading to poor or unacceptable quality. In addition, disintegration time of ODFs is important, as it may significantly affect drug release and thereafter absorption and bioavailability.
