Thermal and thermo-oxidative stability of the PAMAMOS dendrimer-based networks is predetermined by the stability of their less stable compositional parts, i.e., the PAMAM dendrimer interior. In nitrogen, thermal degradation occurs in two steps. 

However, when tested with NaCl and methylene blue water solutions, these PAMAMOS dendrimer-based networks behaved completely differently. For example, while permeability was excellent for sodium chloride dissolved in water, the films turned out practically impenetrable for methylene blue. The latter showed strong tendency towards complexation and encapsulation into the hydrophilic PAMAM domains, as manifested by coloration of the resulting samples. 

The PAMAMOS dendrimer-based networks can be prepared in a variety of different chemical compositions as elastomers, plastomers or coatings, depending on the particularly desired end-application(s). They also contain well defined (in size and shape) hydrophilic PAMAM and oleophilic (hydrophobic) OS nanoscopic domains which are covalently interconnected in a three-dimensional network continuum. These... 

As already introduced in Section 2.4, angular dependent NEXAFS spectroscopy is a powerful tool in the study of self assembled systems, and was successfully applied to the investigation of self assembled monolayers and multilayers of molecular-based NLO materials. Among others, Bubeck and co-workers [70] investigated the interaction of Cu " with C, N and O moieties in nanocomposites containing copper ions complexed in poly(amidoamine-organosilicon), PAMAMOS (dendrimer molecular structure is shown in Fig. 4.19).
