MOF-74 Nanofibers as an Advanced Porous Material for Air-Bearing Technology.

ABSTRACT: Aerostatic bearings are an important technology that utilizes a thin film of pressurized air between bearing surfaces to enable frictionless movement. In this work, the use of MOF-74 (Cu) fibers as an innovative material for porous restrictors in aerostatic bearing devices is proposed. MOF-74 (Cu) fibers are synthesized using a newly developed, green, template-free approach that produces ultra-long and robust fibers with excellent mechanical properties. These fibers can be easily processed into free-standing films and composites, offering a scalable and cost-effective method for producing air-bearing pucks. Tests under operational conditions for low-pressure air bearings demonstrate the reliable structural and mechanical strength of the MOF-74 (Cu) fibers, positioning them as a promising alternative to traditional bearing materials. This advancement not only sparks the development of air-bearing technology, but also broadens the potential for MOFs in real-world applications, paving the way for green and sustainable manufacturing solutions.
