Paper-Scaffolded Carbonaceous Materials for Disel Particulate Filters
Inventors: Dr. Rodrigo Martinez-Duarte
Keywords: Polymers/Composites, Sustainable Manufacturing, Automotive
Market Overview
As new legislation is passed in effort to reduce the effects of vehicle exhaust pollution on the environment, automotive manufacturers struggle with the high cost of implementing diesel particulate filters (DPF) and diesel oxidation catalysts (DOC). The global market for DPFs and DOCs was estimated to be worth $77.5 billion in 2015, with an expected annual growth rate of 7.00-7.86%. However, the high cost of the required manufacturing materials presents an obstacle for this expanding market. Clemson University researchers have developed novel carbonaceous materials technology to address these challenges. Using cellulosic paper, complex two- or three-dimensional shapes that can be created and treated to produce glassy carbonaceous structures that can then be incorporated into DPFs and DOCs. This innovation would allow for diesel filtration devices to be manufactured for a fraction of the cost of the materials currently used by the industry for this purpose.
Applications:
Catalytic converters, particulate filters
Technical Summary:
This technology is based on the fabrication of complex carbonaceous parts using paper as scaffold. Cellulosic paper can be functionalized with different inks containing metal precursor. Pure or functionalized paper can then be patterned by folding, shearing, cutting, and/or punching to obtain complex two- or three-dimensional shapes with complex geometries and thin cross-sections. This patterning is automated and exhibits a high level of reproducibility in manufacturing settings. The paper-reinforced patterns are then heat treated in an inert atmosphere with specific protocols to derive one of three possible choices: a glassy carbon material, a glassy carbon decorated with metal nanoparticles, or a metal carbide. These carbonaceous structures can then be further infiltrated with polymer, ceramic or metals to further tailor the properties of the material.
Advantages:
- Uses paper folded into origami-like shapes, enabling creation of complex structures in the final product.
- Requires cellulose as opposed to other materials, lowering the cost of production
