My group has been developing new materials composites for fused deposition modelling 3D printers. This research has taken two directions that are of interest to the direction of this symposium in the ACS Division of Environmental Chemistry. First, we have incorporated different metal organic framework (MOF) powders into acrylonitrile butadiene styrene (ABS) filaments. Our intention is to generate 3D printed objects that can be used in applications that require hydrogen as a fuel source. I will discuss the gas uptake and delivery properties of these materials. Second, we have incorporated cellulose nanocrystals (CNC) into ABS filaments at 25% by weight loading. The high loading percentage in a material that maintains its mechanical and high-temperature, rheological properties is enabled by an ion exchange process developed by my colleague Douglas Fox at American University. The CNC-ABS composites are meant to highlight the ability to generate industrially relevant materials using renewable feedstocks.
