| description | Conducting polyaniline is unique among conducting polymers on account of its excellent optical
and electronic properties. The processing of conducting polymers has attracted considerable
attention owing to their possible application in molecule‐based electronic devices, such as
molecular rectifiers, field‐ effect transistors, molecular transducers and sensors. Methods that
were applied in this study are addition method (powder), liquid homogeneous method and
filtration method. The effects of bonding between methanol and Polyaniline emeraldine base
(PANI‐EB) has been investigated. UV‐visible spectrum shows two sharp absorption peaks at
350nm (π‐ π*) and ∼720nm (polaron bands). FTIR spectra proved there is a distinct increase in
wave number when PANI‐EB dissolved in methanol which caused by the H‐bonding interaction
between PANI‐EB chains and methanol. Thus this make the PANI‐EB molecules change in size
that supported by a DLS result. As a conclusion, it indicates that there is interaction between
methanol molecules and polyaniline chains. |
