Measuring Nanoparticle Permittivity in Colloidal Suspension

Sandia National Laboratories
2012–13

The Sandia National Laboratories clinic team 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.
