Thermal transport in polymers a review

The role of crystallinity, chain orientation, draw ratio, temperature, and chain length/molecular weight of these materials on the thermal transport will be discussed. A special emphasis is Abstract. The demand for flexible conductive materials has motivated many recent studies on conductive polymer-based materials. However, the thermal conductivity of conductive polymers is relatively low, which may lead to serious heat dissipation problems for device applications. This review provides a summary of the fundamental principles for thermal transport in conductive polymers and their composites, and recent advancements in regulating their thermal conductivity.

The thermal transport mechanisms in conductive polymer–based materials and up‐to‐date experimental approaches for measuring thermal conductivity are first summarized. 2016-10-06 · Understanding the thermal transport characteristics of amorphous thin films is important for the thermal design and management of these novel electronic devices. Furthermore, amorphous dielectric materials, such as SiO 2 , HfO 2 , and SiN x , are widely used as inter-conductor gate dielectric layers in microelectronics [ 14 ]. It is hoped that the present review could provide better understanding of the thermal transport properties of recently developed 2D nanomaterials and various 3D nanostructures as well as relevant polymer-based TIMs, shedding more light on the thermal management research.

In this review article, we aim to: 1). systematically summarize the molecular level understanding on the thermal transport mechanisms in polymers in terms of polymer morphology, chain structure and Here, we show that a phase-changing polymer with hysteretic thermal transport properties can be experimentally processed into thermal memories at room temperature. We used a temperature-responsive and reversible polymer synthesized with melamine (M) and 6,7-dimethoxy-2,4[1H,3H]-quinazolinedione (Q) as a model system to demonstrate the In this review, we focused on exploring different types of organic thermoelectric materials and the factors affecting their thermoelectric properties, and discussed various strategies to improve the performance of thermoelectric materials.

Zozoulenko‡ Laboratory of Organic Electronics, ITN, Linkoping University, SE-60174 Norrk¨ oping, Sweden¨ Thermal transport efficiency in polymers is largely attributed to the quality of the lattice structure (i.e. crystallinity and chain alignment). It can therefore be understood that the degree of organization within the polymer matrix, and the degree of crystallinity of the polymer chains will heavily influence the conductivity your sample.
