Ultimately, we provide the membrane design community with many novel high-performance polymer candidates and key chemical features to consider when designing their molecular structures. Many of the concepts demonstrated here can likely be extended to other materials discovery and design tasks, such as polymer membranes for desalination and water treatment , high-temperature fuel cells , and catalysis . With the continual improvement of ML techniques and an increase in computing power, we expect that ML discovery frameworks will only gain popularity and deliver increasingly substantial results in materials discovery for a wide range of applications .
