| Outline of Annual Research Achievements |
In 2023, we continued the validation of the virtual libraries, as originally planned. We also successfully refined the ensemble of polymer generators within the XenonPy platform, our open source software developed in this project, based on the new measurement results for the synthesized polyimides last fiscal year. Candidates in the virtual library are further filtered using state-of-the-art clustering algorithm and a new model for solubility estimation of polymers in different solvents in order to help the polymer scientists ranking the order for synthesis trials. Our analyses demonstrated that the data-driven polymer design approach based on our generative models is effective on discovery of new functional polymers with desired properties. A total of six new polyimides that were confirmed to exhibit liquid crystalline structure through X-ray diffraction measurement. Our models also continue to contribute to the RadonPy project, which is a collaborative national project between academia and industry to form the largest open calculation database for polymers. This project is just a starting point and we will continue to expand the capacity of our generative models and predictive models for different polymer type and polymer properties to set the groundwork for future innovations in polymer design and materials science.
