Oil and Water Separation Mesh

 

Novel Mesh Coating Allows for Separation of Oil From Water, Water From Oil

Research at Ohio State’s Nanoprobe Laboratory for Bio and Nanotechnology and Biomimetics has recently developed a new novel mesh coating which allows for the separation of oil from water or water from oil. The filed patent application protects the multi-layered coatings and methods of use for separation and surface treatment. The proprietary coating is comprised of known compounds and is applicable to a range of commercially available meshes. The final product has been shown to be resilient and can effectively filter oil or water from a mixed solution.

Research

The simple fabrication procedure created and documented by the laboratory allows for the creation of meshes that are superhydrophobic, superhydrophilic, superoleophobic, superoleophilic or a combination thereof.

The patent-pending composite nanoparticle coating and method of application was developed and then applied to commercially available stainless steel mesh (#400) with limited preparation. Resilience was tested by repeatedly deforming the mesh and testing again which created no noticeable degradation in performance.

Inventors

The novel composite nanoparticle coating was developed by Dr. Bharat Bhushan and Dr. Philip S. Brown at The Ohio State University's College of Engineering.

Matteo Triberti, of Ohio State's CDME, developed the automated spray deposition process for repeatable, even distribution of the composite nanoparticle coating.


Want to be involved:

The Ohio State University is seeking industry partners who would benefit from this novel separation mesh. The Center for Design and Manufacturing Excellence (CDME) will work with partners to develop samples of the separation mesh for initial testing. If customization of the mesh is required for the industrial application, CDME and the industry partner will work directly with Dr. Bhushan’s laboratory on a comprehensive research program. CDME will also work with partners to develop engineering solutions for the intended application of the mesh.

The goal

The goal of this program is the active commercialization of a series of durable and effective mesh separation systems.
