Abstract
A method of preparing stable waterborne polyurethane nanocomposite with a long shelf-life time is described. The stability of the nanocomposite is achieved by effective mechanical and sonication mixing of diisocynate and clay. Also, the stability is achieved through optimization of the amount of clay and carboxylic acid with hydroxyl functionality.
