    • 2. Taking the larger number, the ratio of the areas per molecule for the two cases is 21. There is uncertainty regarding the number of bonds between the crosslinker and the substrate surface. There are six reactive protons per T403 molecule, but it seems unlikely for geometrical reasons that all would interact with the substrate. For this estimate we assume two bonds to the substrate per T403 molecule. This is an assumption that needs to be examined experimentally. With this assumption, the ratio of the number of interfacial bonds per area for the SAM and epoxy cases is 10.5. This value is believed to be an upper limit. Preferential segregation of the crosslinker to the interface would result in a lower factor. A lower factor will also result if the average number of bonds to the substrate per T403 molecule in the surface layer is greater than two.
