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
Stability study of polymer inclusion membranes (PIMs) based
In fact, a membrane exhibiting a hydrophilic character promotes the penetration of water and the hydration of the membrane, therefore the transport of target molecules, while a hydrophobic character ensures good stability of the membrane by delaying the leakage of the liquid phase (carrier and plasticizer or modifier) into the adjacent aqueous
Plasticizer - an overview | ScienceDirect Topics
As the molecular weight of plasticizer is increased, permanence at room or elevated temperature improves. Volatile loss from plasticized PVC is subject to two major controls governing transfer to matter. There is resistance to the movement of plasticizer from inside the mass to the surface and a resistance to loss from the surface.
Structural Characterization of the Plasticizers’ Role
Since the influence of the plasticizer in transport is dependent on the degree of plasticity, which is largely dependent on the chemical structure of the plasticizer , as well as on its interactions with the other components of the membrane system [14,18], it is expected that the generated information will be helpful in the understanding of the
Plasticizers – Benefits, Trends, Health, and Environmental
Plasticizers soften the PVC to make it flexible and bendable. This opens up a huge range of possibilities for new applications. One of the main benefits of plasticizers is the durability they confer onto PVC applications, which can ensure high performances for up to 50 years.
- Do plasticizers affect transport eficiency?
- The plasticizers were found to significantly affect the characteristics of membrane hydrophilicity, mechanical flexibility, and thermal stability. Transport experiments using Hg(II) as a model target ion revealed that, for CTA-based PIMs, the plasticizer did not significantly affect transport eficiency.
- Do plasticizers enhance lithium ion transport in PEO-based solid polymer electrolytes?
- Enhanced lithium ion transport in PEO-based solid polymer electrolytes employing a novel class of plasticizers Ionic conductivity studies in composite solid polymer electrolytes based on methylmethacrylate Effect of plasticizer and lithium salt concentration in PMMA-based composite polymer electrolytes Int. J. Electrochem.
- Why is plasticizer important?
- Plasticizer facilitates the reduction of crystalline nature of the polymer matrix and also increases the polymer segmental mobility. It further results in greater ion dissociation which allows greater number of charge carriers for ion transport in the electrolyte.
- Does plasticizer incorporation in polymer-salt preferably poly (vinyl alcohol) affect electrical and electrochemical properties?
- In summary, it is concluded from the literature reports and our experimental work that plasticizer incorporation into polymer-salt preferably poly (vinyl alcohol) as host polymer and LiClO 4 as ionic dopant can have great impact on electrical and electrochemical properties.
- Do plasticizers affect the mechanical and thermal properties of polymer inclusion membranes?
- Abstract: This study investigated the influence of various plasticizers commonly used in the manufac-ture of polymer inclusion membranes (PIMs), such as 2-nitrophenyl octyl ether (NPOE), phthalates, adipates, and sebacates on the mechanical, thermal, and transport properties of membranes.
- Does plasticizer affect structural properties of polymer-salt matrix?
- The combined effect of filler and plasticizer on polymer-salt matrix can lead to better electrical, electrochemical as well as thermal properties. 3. Conclusions Effect of inclusion of plasticizers on structural properties of polymer electrolytes is discussed with aid of literature reports available.
