Table 1 floss ofvarious paper substrates estimated from the model established using non-capillary substrate. A higher floss value for a substrate indicates higher capillary absorption ability. The conductivity of ECA with 50 wt% of silver filler is listed to show the benefits from binder absorption quantitatively
