Humidity-dependent dynamic water (mass) uptake of ionomers and hydrophilic materials at a controlled temperature (20-85C) to determine sorption isotherms, dynamic diffusion coefficients, residual water. Also works with select organic solvents (vapors)

Mass and volume measurement of materials using air-displacement methid to determine density and porosity of materials

Quartz-Crystal Microbalance with Dissipation for ionomer dispersion adsorption and ionomer thin film mass change (hydration) on supports (metal-coated substrates) to investigate the ionomer-metal interfaces and interactions

Measures and analyzes dynamic mechanical and rheological properties of materials (viscosity vs. shear rate)

Measuring particle size distribution and chemical properties ionomer dispersions and inks to quantify the effects of chemistry, catalysts and solvent compositions

Measuring contact angle, sliding contact angle, adhesion force of components using 2-camera setup and computer-controlled liquid injection system

Measure mass change with heating to determine the residual water loss (dehydration at high temperature), mass loss, thermal decomposition at high temperatures
