Abstract

The invention describes a novel thermoelectric composite material containing electrically conductive polymeric fibrils in a polymer matrix with a high thermoelectric coefficient. The invention also includes a thermoelectric device using the composite. The invention also includes a thermoelectric device containing a thermoelectric layers and a thermoelectric device in which a thermal barrier isolates a thermoelectric layer from a structurally supporting substrate. The thermoelectric devices can be used to generate electricity or to control temperature.

First claim

What is claimed:

1. A thermoelectric composite material, comprising:
conductive organic fibrils, and a polymer with a high Seebeck coefficient of at least 40 microvolts per degree Celsius (μV/C);
wherein the organic fibrils have a conductivity of at least 10 6 Siemen per centimeter (S/cm);
wherein the conductive organic fibrils are dispersed in the polymer with the high Seebeck coefficient.

2. The thermoelectric material of claim 1 wherein the fibrils…
