Outline of Final Research Achievements

In this project procedures to prepare temperature responsive nanogel particles whose pKa value can be reversibly shifted in response to temperature change has been studied. We found that pKa value of carboxylic acids in the nanogel particles can be tuned by polymerization pH, amount of hydrophobic monomers and cross-linking degree. Thermo-electrochemical cells was developed using nanogel particles as electrolyte. The cells showed Seebeck coefficient of -6.2 mV K-1 by using the combination of proton-coupled electron transfer chemicals and the nanogel particles.
