3D Printing of Nanocomposite Membrane and Piezoelectric Sensors—Towards ML-Guided Design and Characterization

Separations based on designed transport are a hierarchical phenomenon that requires an appreciation of surface chemistry, polarization effects, and pore characteristics. Applications in energy and sustainability materials will use new materials and fabrication technologies. 3D Printing combines materials design and geometric-function-based manufacturing at the macroscopic level. This talk will focus on controlled transport from layers and patterns in thin films and using 3D printing methods to control function: 1) the 3D Printing of polyvinylidene fluoride (PVDF) membranes and surface morphology control that enable oil-water separation and emulsion breaking. 2) the 3D Printing of multi-material silicone materials with controlled wetting and high resolution. And 3) using percolation theory, the 3D-printing actuators and sensors with hyper PVDF-MXcene piezoelectric materials. Thus, these examples demonstrate the potential for multi-scale materials with geometric and digital design strategies in the digital manufacturing of polymer and composite systems.
