Morphology of PANI on Paper

Polyaniline-paper composite is prepared on a paper template by interfacial polymerization. Using SEM and FESEM, the morphology of PANI on fiber and pores between fibers are inspected based on different polymerization. The flake shape of PANI is formed on fiber surface at the beginning due to electrostatic attraction, while the granular is growing on the pores freely. This flake shape on fiber is changed with 3rd polymerization into granular. When the resistivity is below 100cm/S, linear PANI in pores is growing to the fiber nearby, and PANI network formed. The morphology also confirmed that PANI on fiber only remains on the upside not fully covered surface of fiber. Very few PANI is found inside paper substrate by cross section SEM. The method is discussed also with polyaniline-fiber composite polymerization and in-site paper polymerization.
