News: DuPont has filed a patent application regarding a material containing Nexam Chemical’s crosslinkers
A patent application filed by DuPont (USA) has become public. The application is regarding a nanoweb of nanofibers based on crosslinked polyimides containing Nexam Chemical’s crosslinkers. The nanoweb is intended to be used in separator membranes in electrochemical cells, such as fuel cells and batteries.The nanofiber is produced from a solution and this solution must have the correct rheological properties, which limits the length of the polymer and the amount thereof in the solution. By using Nexam Chemical’s crosslinking technology and products DuPont has succeeded to increase the amount
