مستخلص المنشور

Polyacrylnitrile (PAN) is a widely used polymer due to its application in surface protective

coatings on metal surfaces and on carbon nanotubes. However, despite the considerable

literature that already exists for PAN, active investigations are still ongoing, especially into

the electrografting or electropolymerization of PAN to produce thin polymer films with the

ultimate aim of producing not only unique and unusual surface structures, but also

functionalised surfaces for a variety of applications that include e-paper and sensor arrays.

Out of the 8 monomers synthesised, 5 produced polymeric films when the monomer was

polymerized by electropolymeization. This is the first time that such monomers, based on the

acrylnitrile structure, have been shown to undergo electropolymerization. SEM showed that

the polymeric film covered the surface of the electrode and that the extent of film formation

was not dependant on the electronic structure of monomer. However, film formation was

greatly reduced for the larger size molecule.
