Figure 1 technique based on inkjet printing is proposed for shows how this angle changes with Triton concentrations the fabrication of supercapacitors electrodes. By from 0.0001% to 5% in weight. Likewise, we have mastering the activated carbon suspension in monitored the behaviour of the solution in test tubes. ethylene glycol through use of a surfactant and by Following storage for 48 hrs, three behavioural types were utilizing a substrate treatment with OTS, 10µm found: wide structures have been obtained with 50µm ink - from 0.0001 % to 0,1%, three phases were jet nozzles. observed (ie, an upper transparent phase, an intermediate homogeneous phase and a lower deposition phase), I.
