摘要：

Copper(I) oxide based compounds are investigated as earth abundant, environmentally friendly thermoelectric materials. Copper(I) oxide powders from different vendors are first examined, resulting in Seebeck coefficients of approximately 650 mu V/K. Pastes of the powders with two different polymer matrices, polychlorotrifluoroethene and polydimethylsiloxane, in various mass ratios produce values reaching 567 +/- 5 mu V/K. Small quantities of transition metal oxides added to the already mentioned compounds produce further enhancements of 729 +/- 4 mu V/K in case of the powders and 606 +/- 5 mu V/K for the polymers. The results offer motivation for further research in the field of thermoelectric pastes, which is still in its foundation stage. (C) 2014 AIP Publishing LLC.
