Abstract:
The key challenges in thermoelectric power conversion are creating a significant temperature difference and obtaining more heat energy through a thermoelectric device. Herein, graphene/polyethyleneglycol composites (G-PEGs) were proposed as a heat supply for thermoelectric devices. The G-PEGs not only afford a lot of conductive pathways for heat transfer but also act as highly thermally conductive reservoirs to hold phase-change materials for thermal energy collection, storage and release. The concept described in this study holds great promise in designing multifunctional composites for heat collection, transport, and supply in thermoelectric power conversion.

Mechanisms of Heat Transfer
Conduction, accounting for approximately 3% of body heat loss at rest, is the process of exchanging heat between molecules of two materials in direct contact. This can result in both heat loss and gain. For instance, when the body is submerged in water, which conducts heat 20 times more effectively than air, it can either lose or gain significant heat.
