The Sandia National Laboratories Clinic Team at 91探花 has characterized the permittivity of barium titanate particles in colloidal suspension as a function of primary particle size, synthesis method, and surfactant choice using electrochemical impedance spectroscopy. To accomplish this goal, the team has built a sample holder to contain the suspension, developed a procedure to extract nanoparticle permittivity from the suspension permittivity, and integrated both of these deliverables into a testing procedure.
