Method for the covalent grafting of a polyarylene film on an electrically conductive or semi-conductive surface

摘要

The method involves immersing a conducting or semiconducting surface of electricity in a solution (12) of aryldiazonium salt or salt precursor with a preset time, and removing the surface from the solution. A part of the surface is in physical contact with an element made of electricity conducting material during the immersion of the surface in the solution, where the material has a standard oxydoreduction potential lower than 0.15 volt at standard oxydoreduction potential provided by the surface. The solution is maintained at temperature equal to 20 degree Celsius.
