Oriented polymers may exhibit high thermal conductivity, but the upper limits remain unclear. Here, the authors show that heat-carrying phonons scatter primarily from crystalline domain boundaries in disentangled polyethylene films.

The term disentangled refers to polymers with fewer entanglements in the amorphous regions, a metastable condition that can significantly affect the material’s properties and processing behavior. The lower entanglement density in ultra-high molecul
