FIGURE 3.54
SEM micrograph of IPMNC and (a) its close-up and (b) x-ray line scan (c),
respectively. The silver penetration is about 7-8
m for this sample and the majority of silver
particulates are in tack within the ion-exchange polymer.

SEM micrograph showing Ag surface properly electroded and composited on
to an ion-exchange polymer.
Also, the surface SEM micrograph provided in figure 3.55 shows fairly uniformly
distributed Ag particles at the surface. Ag particles stay intact so as to function as
the highly conductive surface electrode. Overall, the surface resistance is lowered
as the penetration of Ag particles increases and reaches slightly below 1
/square.
Note that surface resistance was measured by the four-probe method (Guardian
Manufacturing, #SRM-232). Performance of the IPMNC manufactured by this newly
