ABSTRACT
With a growing demand for better materials in more demanding applications, polymer-based materials, combined with micro and nanomaterial, are often the best option. In many material applications, the transparency,

low weight, and corrosion resistance are key features. Nevertheless, polymer matrices are not as tight as they look. Solubility, and subsequent diffusion, of chemicals in polymers is a drawback.* On the „rst place, chemical solubility and diffusion might alter the integrity of the composite itself (see Figure 15.1).
