The Electrodeposition of Colloidal Materials onto Paper.

The controlled formation of thin homogeneous films onto metallic objects can be accomplished by the process of electrodeposition. This research investigates utilization of the same transport process to deposit films from aqueous colloidal systems onto paper substrates. Such a technique was found applicable provided the paper fiber matrix was sufficiently impervious to the colloidal particles and if gassing did not interfere with the film formation. It was also determined that if the paper was externally sized with a film-forming conductive polymer then it would behave as well as a metallic conductor in accepting electrodeposits of coating materials.
