Composite Materials Manufactured by Photopolymer 3D Printing with Metal-Organic Frameworks

Abstract

New composite materials containing metal-organic framework (MOF-5) particles were manufactured by 3D printing. The optimal composition of the photopolymer formulation and printing conditions ensuring the highest quality of printing were selected. Retention of the metal-organic framework (MOF) structure in the resulting composite objects was demonstrated by powder X-ray diffraction. The distribution of MOF-5 particles over the whole bulk of the 3D product was studied by X-ray computed tomography. In the future, composite materials of this type containing catalytically active MOFs, with their structure and properties being controllable at the micro and macro levels, could find application as catalysts of various chemical processes.

3D-Printed Porous Magnetic Carbon Materials Derived from Metal–Organic Frameworks

“…Pyrolysis of MOFs is known to produce highly porous carbon materials with uniformly distributed metal particles [52]. If MOFs are incorporated into a photopolymer composition [19,29], such materials can be obtained in a variety of complex geometries for use in catalysis [13]. To increase their porosity, however, the use of a larger amount of a MOF is not an option, as its content dramatically affects the processibility of the photopolymer composition.…”

“…Sometimes chosen as fillers in composite materials for 3D printing [19], metal-organic frameworks (MOFs) are porous crystalline solids made of metal ions or its clusters and organic linkers [20]. Their high surface area, tunable pore size and other engineerable properties [21] make them useful in gas separation and storage [22,23], heterogenous catalysis [24], medicine [25], sensors [26], etc.…”

Photopolymer-metal Composites Based on Metal Foil Deposition on Additive Manufactured Substrates: An Overview

“…The metal layer provides the material with properties such as electrical conductivity, thermal conductivity, and mechanical strength, while the polymer substrate provides flexibility, ease of processing, and chemical resistance [6] . The photopolymer-metal composite materials produced through this process have a wide range of potential applications, including in the fields of electronics, sensors, rotary blades, and biomedical engineering [7][8][9][10] . For example, they could be used to create flexible circuits or biosensors with metal contacts embedded in a polymer substrate.…”

“…It allows for the creation of functional components with the desired properties required for the application. Yes, coating a metal foil onto photopolymer materials can significantly improve their mechanical and tribological properties compared to photopolymer materials [8,11] . The metal foil can act as a reinforcement material, providing additional strength and stiffness to the composite material.…”

“…Overall, the addition of a metal foil can enhance the properties of photopolymer materials and make them more suitable for a wider range of applications, particularly those requiring higher mechanical or tribological performance. One example of a photopolymer-metal composite that utilizes a metal foil to improve mechanical and tribological properties is a metal-polymer composite used in automotive brake pads [8,11] . The brake pad composite material consists of a polymeric matrix, typically made of phenolic resins, reinforced with metal fibers or metal foil.…”
