Charge relaxation control

In order to obtain the current consumed during the nucleated relaxation process under a constant potential, we assume that a stationary density of charge (<, ) will be stored in the polymer at the polarization potential E. The storage of these charges is controlled by both conformational relaxation (3r) and diffusion ( processes, so... 

Taking into account the variation in the oxidized area as a function of the overpotential, and the counter-ion flows, the charge consumed during the potential sweep in those regions where the structure was previously opened under conformational relaxation control, is given by... 

As in chronoamperograms, the fraction of the overall oxidation charge involved in relaxation processes is quite small in the absence of any external stress. The share of the overall current at every potential between electrochemical processes occurring under relaxation control and those driven by swelling-diffusion control can be observed in Fig. 66. I(r) has...

The overall charge (Qt) consumed to oxidize the film by a potential step from Ec to E has two components the charge consumed to relax the compact structure, which will be called the relaxation charge (Qr), and the charge consumed under diffusion control to complete the oxidation, called the later diffusion charge (Qd)- The following equation is obeyed ... 

An infinitesimal fraction of the polymer will be considered, consisting of all the segments that are relaxed at the same time (f). As result of the flow given by Eq. (32), the increment of charge stored under diffusion control [dQd(t) in this infinitesimal portion of the polymer at a given time t>f, will be given by... 

The charge consumed by oxidation swelling under diffusion control, once the structure is relaxed, depends on the anodic potentials applied at each moment. The process can be quantified by Fick s law ...
