Thermoelectric material converts a difference in temperature to an electric potential or, conversely, an applied voltage to a difference in temperature This phenomenon has made these materials attractive for their potential in applications extending from microprocessor cooling to turbocharger & power industry. Shape Memory Polymers-(SMPs) ,represent co-polymers which generally the structure consists of two type of components. One component,like nanostrip multilayers, with the higher glass transition or melting temperature, represent the hard component. This hard component (elastomer) represent the main element of SMPs, which improve the tribological (wearing resistance) properties and provides the mechanical strength of SMPs at high temperature, Ttrans, where the soft component (thermoplast), which stabilizes the hard component at low temperature looses its strength.

Thermoelectric phenomena provide the direct conversion of heat into electricity or electricity into heat, the phenomena is described by three related mechanisms: the Seebeck, Peltier and Thomson effects.

To realize pseudo-composite material: Unidirectional Carbon nFiber (UCnF) Reinforced shape memory polymers-(SMPs) nanostrip multilayers material -Vyborcntmat-SMP ( VycnT) is a challenge for new generation of turbochargers to limit diesel-cars exhaust hot and dangerous gases and protect life and the environment.

This work describes the investigation SETEC-MTN Research-laboratory IMNR-INCDMNR-Bucharest,Romania, and D8 DISCOVER with GADDS -BRUKER AXS – Germany.
