Toward 3D printed hydrogen storage materials made with ABS‐MOF composites

Abstract

The push to advance efficient, renewable, and clean energy sources has brought with it an effort to generate materials that are capable of storing hydrogen. Metal-organic framework materials (MOFs) have been the focus of many such studies as they are categorized for their large internal surface areas. We have addressed one of the major shortcomings of MOFs (their processibility) by creating and 3D printing a composite of acrylonitrile butadiene styrene (ABS) and MOF-5, a prototypical MOF, which is often used to benchmark H 2 uptake capacity of other MOFs. The ABS-MOF-5 composites can be printed at MOF-5 compositions of 10% and below. Other physical and mechanical properties of the polymer (glass transition temperature, stress and strain at the breaking point, and Young's modulus) either remain unchanged or show some degree of hardening due to the interaction between the polymer and the MOF. We do observe some MOF-5 degradation through the blending process, likely due to the ambient humidity through the purification and solvent casting steps. Even with this degradation, the MOF still retains some of its ability to uptake H 2 , seen in the ability of the composite to uptake more H 2 than the pure polymer. The experiments and results described here represent a significant first step toward 3D printing MOF-5-based materials for H 2 storage.3

CelloMOF: Nanocellulose Enabled 3D Printing of Metal–Organic Frameworks

“…As compared to these techniques, 3D printing offers valuable advantages, such as high reproducibility, fabrication of complex geometries, controlled pore structures, tailored directionality, low cost, time effectiveness, and up‐scalability. However, 3D printing of MOFs usually requires additive materials, such as bentonite clay (as a binder) and polyvinyl alcohol (as a plasticizer) in ethanol, acrylonitrile butadiene styrene, poly(lactic acid), thermoplastic polyurethane matrices, and photopolymers, while demanding high processing temperature of up to 230 °C or ultraviolet curing. 3D printing of a composite containing MOFs has only been investigated to a limited extent.…”

3D‐Structured Monoliths of Nanoporous Polymers by Additive Manufacturing

“…Hence, more common is the printing of composite monoliths. Several recent reports proved the concept to print various MOFs with typical thermoplastic polymers such as acrylonitrile butadiene styrene (ABS) and polylactic acid (PLA) .…”

3D Printing and Digital Processing Techniques in Dentistry: A Review of Literature

“…3D printed ABS architectures have been tested under compressive loads for the sake of analyzing the role of printing direction, density, printing time, and filler shape on their stiffness, strength, and failure mechanisms. Analysis of the stress–strain ( σ – ϵ ) curves indicates that stiffness and limited strength are rendered higher accordingly by raising the filling content . As we continue to develop this technology, we hope to reduce production costs, increase production efficiency, and make it used more widely.…”
