Concept of Recycling‐on‐Demand Investigated on Linear Poly(Ester‐Co‐Acetal)s
ABSTRACT Effective recycling of polymers into valuable resources is the basis for establishing a circular economy. Whereas mechanical recycling often leads to downcycling, the concept of recycling‐on‐demand (ROD) has high promise. The aim is to design next‐generation polymer materials that combine…

Influence of Polyvinylpyrrolidone on Thermoelectric Properties of Melt-Mixed Polymer/Carbon Nanotube Composites
For thermoelectric applications, both p- and n-type semi-conductive materials are combined. In melt-mixed composites based on thermoplastic polymers and carbon nanotubes, usually the p-type with a positive Seebeck coefficient (S) is present. One way to produce composites with a negative Seebeck…
