Viscoelastic potential-induced changes in acoustically thin films explored by quartz crystal microbalance with motional resistance monitoring

Abstract

for a net liquid-loading effect on resonator electrode. Therefore, as this value is larger the film deposited on resonator electrode is expected to be more rigid. The experimental results showed in this work points to this assumption. Viscoelastic state of acoustically thin films of poly(o-toluidine) were investigated through redox reactions, in different electrolytes and scan rates potential perturbations. Finally, viscoelastic changes of a relaxed POT and packed POT was compared. The viscoelastic aspects of poly(otoluidine) here investigated can help to understand and adjust the signal transduction of (bio)sensors or for composite supercapacitors where the mechanical properties of the different organic layers can limit the performances of the electrochemical system.

Scrutiny of the LiCoO2 Composite Electrode/Electrolyte Interface by Advanced Electrogravimetry and Implications for Aqueous Li-Ion Batteries

“…A reliable region is defined as ΔRm/Δf ratio ≤ 0.01 Ω•Hz -1 . 47 respectively. The other observation is that the mass decrease during oxidation is lower than mass increase during reduction (Figure 2a).…”

Quantification of porosity in extensively nanoporous thin films in contact with gases and liquids

“…3). Several research groups have greatly contributed to the advanced use of concepts of QC admittance for the experimental assessment of raw data and their further modeling 32–35 . The mass density of the viscoelastic layer expressed by the product of the specific gravimetric density and the thickness of the layer is one of the fitted parameters, in addition to its complex shear modulus.…”
