| Summary: | Polyaniline (PANI) is one the most extensively studied conductive
polymers owing to several unique properties that made PANI superior to other
conductive polymers, pH sensitive conductivity and color, high environmental
stability, ease of preparation into different morphologies, and low cost.
Morphology control of PANI has always been a major topic of research due to
the promising application potential of several morphologies of PANI with
unique properties, such as nanotubes, nanofilm, and hollow microsphere in the
field of analytic science, electronics, energy storage and conversion, and
medicine.
Vapor diffusion is a material self-assembly method introduced by
Yamamoto et al. as a method to prepare conductive polymer hollow
microspheres for optical resonator application. The vapor diffusion method has
the advantage of being simple, low-cost, and low-energy. In this research the
vapor diffusion method is used to fabricate PANI particles, with NMP
(n-methyl-2-pyrrolidone) as good solvent, and water as poor solvent. Between 1
day to 30 days of fabrication, PANI particles with 3 distinct morphologies has
been sucessfully fabricated. PANI submicrosphere with average diameter of
318 nm, PANI ellipsoids with average length of 4 ?m and average diameter of 1
?m, and needle-like PANI with average length of 46.5 ?m.
