Project

Thermoelectric materials can directly convert waste heat to electricity. Thermoelectric energy conversion is an important technique to save waste heat in our lives. Only inorganic thermoelectric materials such as Bi2Te3 have been researched and developed. Most of them are, however, hazardous to environment such as that 1) main elements are heavy metals, 2) synthesis energy of materials is high, 3) manufacturing energy of thermo-modules is high, 4) difficult to separate and recover. Polymers are characterized by light element system, abundant resources, low synthesis and production energy, and ease to separate and recover. These characteristics are superior to those of inorganic materials concerning to environmental burden. Conductive polymers are likely to realize environmentally conscious thermoelectric devices. The present problem is very low Seebeck coefficient as well as unstable electrical conductivity. In our group we have work to the synthesized new polymers based 2,7-carbazole units. These new polymers permit us to reach 19 mW.m-1.k-2 of power factor and very high electrical conductivity values up to 500 S/cm. These highs electrical conductivity was obtained especially with high structured polymers which are sensitized in our laboratory. We have also demonstrated the stability at the ferric chloride doped states of this new family of polymers.  We have noted that they performed under argon and air atmosphere up to one week.
