Reference #: 01246

The University of South Carolina is offering licensing opportunities for Scalable Production of Ultrathin GO-Based Membranes/Coatings by Printing

Invention Description:

This invention is about a novel, scalable method to quickly and controllably deposit ultrathin GO membranes/coatings via facile printing process on various porous substrates and fabrics. The printed GO membranes can be used for water purification by nanofiltration to remove organic contaminants, such as endocrine disrupting compounds (EDCs), and pharmaceuticals and personal care products (PPCPs), and salts in water to produce drinking water. The printed GO membranes may also be used for organic dehydration by pervaporation and for gas separation. Also, the printed hydrophilic GO coatings on various porous substrates and fabrics may be used to improve wetting of aqueous solution.

Potential Applications:

Printed GO membrane can be used for a wide variety of applications, including:

  1. Desalination
  2. Removal of small organic contaminants in water
  3. Pervaporation for organics dehydration
  4. Gas separation

Advantages and Benefits:

Low-cost operational equipment and supplies significantly decrease GO membrane/coating production price.


Polymeric and ceramic membranes are the current benchmark technology for nanofiltration, gas separation, and pervaporation membranes. However, the current membranes are very expensive and energy intensive. For example, low water flux, and separation factor, as well as high operating pressure of commercial nanofiltration membrane cause high water purification costs. GO membranes have a great potential to increase separation performance and remarkably decrease production cost. However, currently scalable and low-cost GO deposition methods are missing. Therefore, it is very important to develop a low-cost scalable GO fabrication technology in order to maintain the cost-effectiveness. The developed printing method in this invention perfectly solves these urgent problems for GO deposition.
