Microfabricated devices enabled an automated methodology to quickly screen redoxmer degradation kinetics at concentrations up to 0.5 M.
Significance and Impact
The ability to perform these experiments at high concentrations will enable high-throughput screening of redoxmer stability at practical concentrations.
- A unique linear relationship was seen between the natural logarithm of collection efficiency and interelectrode gap width that holds of a range of degradation rates.
- Experiments were ran automatically using custom multiplexing hardware and python library for universal potentiostat control.
- Microfabricated devices were designed to handle non-aqueous solvent and plasma cleaning for electrode defouling.
