Book Description
Power generation from environmentally friendly sources has led to surging interest in thermoelectrics. There has been a move toward alternative thermoelectric materials with enhanced performance through materials and structures that utilize common and safer elements and alternative mechanistic approaches while increasing processing latitude and decreasing cost. This wide-ranging volume examines this progress and future prospects with the new technologies, ease of processing and cost as major considerations, and will benefit active researchers, students and others interested in cutting-edge work in thermoelectric materials. Innovative Thermoelectric Materials incorporates the contributions of a group of recognized experts in thermoelectric materials, many of whom were the first to introduce various materials systems into thermoelectric systems. The perspectives brought to this evolving subject will provide important insights on which those developing the field can build, and will inspire new research directions for the future.

Book Description
Thermoelectric materials are scrutinized as energy materials and sensing materials. Indeed, they convert thermal energy into electrical energy. In addition, those materials are actively sensitive to a temperature modification through the generation of an electric signal. Organic thermoelectric (OTE) materials are complementary to inorganic thermoelectric materials, as they possess unique properties such as solution processing, ionic conductivity, flexibility, and softness. While thin-film OTE materials have been widely studied because they are easily manufactured by various coating techniques, little is done in the creation of three-dimensional morphologies of OTE materials; which is important to develop large temperature gradients. Cellulose is the most abundant biopolymer on the planet. Recently, the applications of cellulose are not only limited in making papers but also in electronics as the cellulose provide 3-D microstructures and mechanical strength. One promising approach to make 3-D OTE bulks is using cellulose as scaffold because of their properties of relatively high mechanical strength, water processability and environmentally friendly performance. The aims of the thesis have been to enlarge the applications of an OTE material poly(3,4-ethylenedioxythiophene) (PEDOT), with an approach of making 3-D aerogels composite with nanofibrillated cellulose (NFC), in two main areas: (1) multi-parameter sensors and (2) solar vapor generators. In the first application, we demonstrate that the new thermoelectric aerogel responds independently to pressure P, temperature T and humidity RH. Hence, when it is submitted to the three stresses (T, P, RH), the electrical characterization of the material enables to measure the three parameters without cross-talking effects. Thermoelectric aerogels are foreseen as active materials in electronic skins and robotics. In the second application, the conducting polymer aerogels are employed as solar absorbers to convert solar energy into heat and significantly increased the water evaporation rate. The IR absorption is efficient because of the free-electron in the conducting polymer PEDOT nano-aggregates. Because of the low cost of those materials and the water stability of the crosslinked aerogels, they could be of importance for water desalination. Termoelektriska material har utvärderats som energi- och sensormaterial. Som energimaterial har de studerats som ett sätt att transformera termisk energi till elektrisk energi, och har använts för kylnings- och uppvärmningsapplikationer. Som sensormaterial kan de känna av temperatur eller temperaturskillnader och tillhandahåller elektriska signaler. Organiska termoelektriska (OTE) material, det vill säga kolbaserade termoelektriska material, är komplementära till inorganiska termoelektriska material eftersom de har unika egenskaper så som processbarhet i lösningsform, jonisk ledningsförmåga, böjbarhet, och mjukhet. Tunna filmer av OTE-material har vida studerats eftersom de är lätta att tillverka via olika beläggningsmetoder, men tredimensionella strukturer är till stor del ett outforskat område och är viktigt för att uppnå stora temperaturgradienter. Cellulosa är ett billigt material som utgör den vanligaste biopolymeren på vår planet. Nyligen så har applikationerna för cellulosa sträckt sig bortom papperstillverkning och används nu även inom elektronik för att förse 3D-mikrostrukturer och mekanisk styrka. En lovande metod för att tillverka 3D-strukturer av OTE-material är genom att använda cellulosanätverk på grund av dess relativt höga mekaniska styrka, processbarhet i vattenlösningar och dess miljövänlighet. Syftet med denna avhandling har varit att bredda applikationerna för OTE-materialet poly(3,4-ethylenedioxythiophene) (PEDOT), genom att tillverka 3D aerogelkompositer med nanofibrillerad cellulosa (NFC). Detta har gjorts inom två områden: (1) Multiparameter-sensorer och (2) solar vapor generators. För den första applikationen så demonstrerar vi att de nya termoelektriska aerogelerna har oberoende signaler från tryck, temperatur och relativ fuktighet. Det vill säga att när materialet utsätts för dessa stimuli så kan signalerna som genereras urskiljas av utan överhörning. De termoelektriska aerogelena förutses bli användbara inom områden så som elektronisk hud och robotik. För den andra applikationen används de elektriskt ledande aerogelena för att absorbera solljus för att omvandla solenergi till värme vilket kan öka förångningshastigheten hos vatten. Absorptionen i IR-området är effektivt eftersom de rörliga elektronerna i den ledande polymeren nano-aggregerar. På grund av den låga kostnaden hos dessa material och våtstabiliteten hos korslänkade aerogeler kan dessa material tänkas användas för vattenavsaltning.

Book Description
In the last 10 years there have been major advances in fundamental understanding and applications and a vast portfolio of new polymer structures with unique and tailored properties was developed. Work moved from a chemical repeat unit structure to one more based on structural control, new polymerization methodologies, properties, processing, and applications. The 4th Edition takes this into account and will be completely rewritten and reorganized, focusing on spin coating, spray coating, blade/slot die coating, layer-by-layer assembly, and fiber spinning methods; property characterizations of redox, interfacial, electrical, and optical phenomena; and commercial applications.

Book Description
This book explores a key technology regarding the importance of connections via an Internet of Things network and how this helps us to easily communicate with others and gather information. Namely, what would happen if this suddenly became unavailable due to a shortage of power or electricity? Using thermoelectric generators is a viable solution as they use the heat around us to generate the much-needed electricity for our technological needs. This second volume on the challenges and prospects of thermoelectric generators covers the reliability and durability of thermoelectric materials and devices, the effect of microstructures on the understanding of electronic properties of complex materials, thermoelectric nanowires, the impact of chemical doping or magnetism, thermoelectric generation using the anomalous Nernst effect, phonon engineering, the current state and future prospects of thermoelectric technologies, transition metal silicides, and past, present and future applications of thermoelectrics.
