Dynamic elastomers have a number of possible applications, including coatings, where improved adhesion through molecularly conforming bonds is desirable not only in the neat polymer, but also relating to nanomaterial incorporation. Polymer networks that include exchangeable bonds, compared to other elastomer designs, can have increased strength at interfaces. The purpose of this project is to examine a model dually cross-linked system with permanent crosslinks between polymer chains and potentially dynamic dative bonds between functionalized polymer and dispersed nanoparticles. To do this, we chose to investigate a system designed for corrosion protection. For anti-corrosion coatings, of which nanocomposites are often investigated, the polymer/nanomaterial interface can determine the performance. We selected a polysiloxane modified with a boron-based functionality and incorporated various quantities of boron nitride nanomaterials. Thermal and mechanical characterization, initial examinations of corrosion protection, and characterization of nanoparticle-polymer interactions will be used to expand understanding and probe behavior of this type of unique dually cross-linking system.
