Mass Production of Waste PVC‐Mediated Bamboo‐Derived Hard Carbon for Ultra‐Long Life Sodium Storage

open access: yesCarbon Energy, EarlyView.
By a scalable PVC‐mediated bifunctional strategy, pre‐carbonized micrometer bamboo powder is converted into a functionally partitioned hard carbon anode with distinct domains. Featuring abundant internal closed pores and surface sp2‐enriched graphitic regions, this anode delivers exceptional high‐rate long‐cycle stability, retaining 93% capacity after ...

Dielectrophoretic model of conductance increase in PVC-graphite thick film during electrical breakdown

open access: yes, 1997
The decrease in resistivity of the polymer (PVC)-graphite thick film resistors with the application of high voltage (or high current) is attributed to dielectrophoretic motion of the graphite particles in PVC medium.
