Poly(۱-amino-۹,۱۰-anthra quinone) coating on stainless steel by electr opolymerization

The rate of corrosion of stai nless steel can be red uced by a thin oxide layer (passive film) formed naturally o n the metal surface [ ۱]. In the l ast decade the conductive polymers have been studied by many authors for application to corrosio n-resistant coating of metals. Conduc tive poly mers coatin g has be en assumed to be a possible treatment for the replacement of the chromate treatment on steel [۲]. Conducting polymers do not only behave as barrier coating on comm on metals in corrosiv e media, b ut also prevent easy reach of corrosi ve ions on metal surfac e due to its own redox electroactivity for lo ng exposur e time in corrosi ve enviroments [۳].
