Thermoelectric Properties of p-type Multiwall Carbon Nanotube Filled Ethylene-Octene Polymer Composites

Popis výsledku v původním jazyce

A thermoelectric (TE) material is a material where a potential difference is generated as a result of a temperature difference where a temperature difference is generated when a voltage is applied. These phenomena can be used to generate electricity and/or control temperature. In this research, we present the HNO3, KMnO4 treated carbon nanotubes with flexible ethylene-octene copolymer (EOC) matrix for efficient thermoelectric power capability. This study shows that thermoelectric power can be dramatically increased by utilizing p-type treatments into EOC matrix. With HNO3 treatment as p-type addition, these flexible composites exhibit a thermoelectric power (Seebeck effect) of 18.19 μV/K, while pristine nanotubes demonstrate 7.06 μV/K. These different types of treatments can demonstrate flexible composites with good conversion efficiency for thermoelectric applications in the future.
