Materials science is founded on the processing-structure-properties (p-s-p) paradigm. Understanding of mechanisms have built up over decades leading to a rich tapestry of knowledge which is used to select and design materials for applications. Unlike metallic alloy systems where databases and predictive tools have been built to up and can enable more rapid materials design, the polymer nanocomposite data/design space is considerably less developed due to the heterogeneity of constituent combinations as well as complexity in polymer and interphase behavior.
Because of the complex mechanisms involved in nanocomposite formation and response, and the isolation of data sets from each other, both the fundamental understanding and the discovery of new nanocomposites is Edisonian and excruciatingly slow. We address this issue by creation of a living, open-source data resource for nanocomposites. NanoMine is built on both a schema and an ontology to provide a robustness to the FAIR (findable, accessible, interoperable and reusable) principles. Nanomine also allows for the registration of materials resources, bridging the gap between existing resources and the end users and making those existing resources available for research to material community. The data framework together with the module tools like microstructure characterization and the FEA simulation tools forms the nanocomposite data resource. Searching and visualization tools are being developed for user to query, visualize, and compare their data with the existing data in our system for design purposes. Tools and models utilizing data sciences and optimization concepts are being developed with the goal of data-driven materials design.
In addition to experimental data on polymer nanocomposites (PNCs), a copious amount of simulation data exists in the literature as well, which is informative for nanocomposite design. Modelling techniques such as density functional theory (DFT) and molecular dynamics (MD) can provide insights into various properties of PNCs, for example, electrical properties, thermal properties, and mechanical properties. To expand the scope of NanoMine, we are developing customized Excel templates for DFT and MD data curation.
