Polyaniline belongs to one of the intrinsically conducting
polymers(ICP) and owns specific properties which include good
environmental stability, ease preparation and so on. Likewise,
multi-walled carbon nantube(MWCNT) possesses high flexibility, low
mass density etc. This thesis contains part one is synthesizing
polyaniline with carboxylic groups contained multi-walled carbon
nanotubes(c-MWCNT) with different dodecylbenzene sulfonic acid
(DBSA) concentrations. The results of electrical conductivity
measurement indicate that adding 0.05 moles DBSA of composite, the
conductivity decreased to 49.30 S/cm. By the thermal analysis, the
Tonset2 of composites decrease with DBSA concentration. It is observed through transmission electron microscopy that the diameter of PANI/MWCNT composites is getting bigger with increasing DBSA
concentrations. Besides, from the contact angle analysis, it can be
realized that the composites tend to be more hydrophilic. Part two is
synthesizing polyaniline with different c-MWCNT concentrations and
discussing the morphology and other properties of composites further.
The results indicate that the conductivity and thermal property of
composites are improved when adding more MWCNT. It is observed
through transmission electron microscopy that the morphology of
composite looks like fiber. Part three is about synthesizing
Epoxy/PANI/MWCNT composites and discussing the conductivity. The
results indicate that the conductivity and film forming are better when Epoxy/PANI/MWCNT composite was prepared with 50phr CTBN.
