Accelerated Computational Design of Multifunctional Polymeric Materials with Machine Learning Dynamics

Completed TRL 3 (started at 2, targeting 3)

Description

Modern computational methods, most notably molecular dynamics, have been used extensively to understand the microscopic behavior of atomic systems. However, despite the fact that these methods are far more computationally tractable than higher levels of theory, physically relevant spatial and temporal scales on the order of millions of atoms over the span of microseconds or longer are inaccessible. These regimes are particularly relevant in settings such as gas separation membranes, thermal transport in self-healing materials, or flexible solid state electrolytes for Lithium ion batteries.

In this work, we propose to develop a framework with which larger spatial and temporal scales can be accessed with molecular dynamics. We will use cutting-edge machine learning techniques, along with a rigorous mathematical formalism, to develop the computational tools needed in order to reduce the dimensionality of all-atom simulations. This dimensionality reduction, termed coarse graining, will provide the link between nano- and micro-scale systems that will allow NASA to design better materials with multiple functionalities, as well as perform large-scale screening of materials based on desired performance metrics.

How to get involved

This is early/mid-stage (TRL 3) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
