Interest in polymer nanocomposites has been increasing because of their unique properties. Since the field draws on a wide range of disciplines, a data resource aimed at adequately supporting the field needs to include vocabulary from many disciplines. We are building an ontology that aims to connect to relevant vocabularies and include well-specified interconnections between those vocabularies. Coverage is determined by a set of use cases. We will describe our ontology along with the growing data resource that it supports and introduce how our ontology-based approach can enable collaborative community research in polymer nanocomposites. Further, we mention how this approach can be leveraged more broadly in material science.
