-Jetting & printing optimization
Jetting & Printing
40°C 35°C 30°C
Number of layers
INK: Graphene+ Polyaniline in NMP
Voltage (or drop's volume)
Drop Spacing (um)
Drop spacing 30 um
4,5,6 : 1 ink layer, dry 5 min 120 °C
7,8,9 : 2 ink layers, dry 5 min 120°C
10,11,12: 3 ink layers, dry 5 min 120°C
13,14,15: 2 ink layers, dry 2 times 5 min
16,17,18: 3 ink layers, dry 3 times 5 min
Best electrode: number 10
3 ink layers, dry 5 min 120°C
Signal ratio: 3.92
-Test the best electrode in order to determine the quantity of ferulic acid of various samples
- SEM image of the electrode surface
- Optimise conditions:
Differential pulse voltammetry
If time test on a real sample
