Simultaneous recovery of high-purity copper and polyvinyl
PVC coverings typically contain plasticizers for flexibility. As such, PVC cables become brittle after plasticizer extraction, causing them to be easily crushed by physical impact. Hence, we extracted the plasticizers from the PVC coverings of electric cables using organic solvents, and then crushed the obtained cable samples by ball milling.
Simultaneous recovery of high-purity copper and polyvinyl
Plasticizers incorporated into the PVC matrix would increase and maintain the free volume to prevent interactions between neighboring polymer chains, which results in flexibility. 47 Thus, when the plasticizers are removed, the free volume of the PVC would be expected to decrease, resulting in shrinkage of the PVC covering.

Effect of Plasticizer on Structural and Electrical Properties
maximum conductivity of PPNCE was found to be 1.05x10-6 for x=50% of plasticizer (at 400C). The effect of plasticizer on the structural and physical properties of polymer nanocomposites was well correlated.

Effect of plasticizer on the conductivity of carboxymethyl
Lithium ion conducting solid polymer electrolyte based on carboxymethyl cellulose (CMC) complexed with lithium tetrafluoroborate was prepared by using solution cast technique. Ionic conductivity was measured using ac impedance analyzer and observed as 8.2 × 106 S cm1 at room temperature. For further enhancement in the conductivity, plasticizer was introduced and it reached up to 3.7 ×
- How does plasticizer affect ionic conductivity of polymer electrolytes?
- The incorporation of substantial amount of plasticizer in the polymer electrolytes enhances the ionic conductivity of polymer electrolytes. Plasticizer facilitates the reduction of crystalline nature of the polymer matrix and also increases the polymer segmental mobility.
- Why are plasticizers used in polymer electrolyte?
- Also, plasticizers are low molecular weight organic solvents when added in polymer matrix; they modify physical properties and increase the segmental mobility thereby enhancing the conductivity of polymer electrolyte.
- 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.
