Ethylene terephthalate and ethylene naphthalate oligomers of defined degree of
polymerization were synthesized via chemical recycling of the parent polymers. The …

The effects of swift heavy ion irradiation on the structural characteristics of Polyethylene
naphthalate (PEN) were studied. Samples were irradiated in vacuum at room temperature …

Ion exchange membranes (IEM) are often applied in the processes of separation and
purification solutions, primarily in the chemical, food, and pharmaceutical industries. Most …

Charging current-time J (t) characteristics for a polar polymer were simulated via a simple
one-carrier model including traps with effective density N t. This model is used to reproduce …

The time evolution of conduction current Jc (t) determined experimentally, in polyethylene
terephthalate, at 373 K, was simulated by using a bipolar charge (electrons and holes) …
