Available in PDF, EPUB and Kindle. Book excerpt: Aerogels are the lightest solids known. Up to 1000 times lighter than glass and with a density as low as only four times that of air, they show very high thermal, electrical and acoustic insulation values and hold many entries in Guinness World Records. Originally based on silica, R&D efforts have extended this class of materials to non-silicate inorganic oxides, natural and synthetic organic polymers, carbon, metal and ceramic materials, etc. Composite systems involving polymer-crosslinked aerogels and interpenetrating hybrid networks have been developed and exhibit remarkable mechanical strength and flexibility. Even more exotic aerogels based on clays, chalcogenides, phosphides, quantum dots, and biopolymers such as chitosan are opening new applications for the construction, transportation, energy, defense and healthcare industries. Applications in electronics, chemistry, mechanics, engineering, energy production and storage, sensors, medicine, nanotechnology, military and aerospace, oil and gas recovery, thermal insulation and household uses are being developed with an estimated annual market growth rate of around 70% until 2015.

This book was released on 2019-10-30 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
