Stimuli-responsive polymer chains grafted into nanoporous materials can produce environment responsive fluid flow for applications that include smart drug delivery, bio-remediation and remote sensing. To accurately model these systems we are developing atomic-continuum fluid mechanics methods that couple flow dynamics with polymer chain structure and properties, which has been used previously for flow through polyglutamic acid, the Navier-Stokes-Brinkman equation is numerically solved using the structure and scaling properties for the polymer. Results will be compared to both direct molecular dynamics simulations for simple polymer models, and to experimental results for more complicated systems.
