Interaggregate space

Eig. 3 schematically shows the structure and resistance contributions of the composites. The resistance of EG particles is very small. Therefore, the total resistance comes primarily from the resistance of the interaggregate space. Re. When adding CB to EP/EG composites, CB particles generated connection... 

In dehydrated Nafion , isolated spherical ionic clusters were calculated to have a 15 A diameter and an intercluster spacing of 27 A. This diameter is significantly smaller than the intercluster distance, which explains the low ionic conductivity observed at low water content. Absorption of water induces the formation of isolated spherical pools of water having a diameter of 20 A, with the ionic groups located at the polymer/water interface. The interaggregate distance is 30 A, indicating that these spherical water pools are still isolated as evidenced by the low ionic conductivity of the membrane. With increasing water content, the diameter of the cluster increases to 40 A while the inter-...
