Configuration interaction matrix formation

The interaction of the various configurations leads to sigma bond formation and this can be pictorialized by reference to the one electron interaction matrix elements responsible for mixing of the various configurations. Typical examples are shown below.

Figure 7.16 shows interface formation with painted substrate. The mechanism of organization was discussed in the previous section. The alignment in the polymer layer plays a large part in polymer-filler interaction in the adjacent layers. The way in which polymer is configured on the substrate surface determines if polymer chains are readily available for interaction with filler. This example shows that it is not only the filler and the matrix which play a role in the interphase organization.
