Piezoelektrik nanomalzemeler kullanılarak elektroaktif polimer üretimi ve uygulamaları

In this research by using barium titanate and carbon nanotube additives composites having silicone elastomer (PDMS) matrix were made to produce electroactive polymer composite. First different temperatures and durations were examined to cure the PDMS silicon elastomer to obtain the one which has higher dielectric constant. After that to measure the barium titanate particle size, appropriate dispersant and particle amount optimization was made. Different weight percent amounts of barium titanate powder were mixed with the PDMS to determine optimum dielectric constant by LCR meter. CNT layer was coated onto the PDMS by stamping. Its morphological and electrical properties were observed by digital microscope. SEM, FTIR and DTA measurement were made to compare the surface morphology and particle distribution, bonding property change by effect of additives and curing regime respectively.
