چکیده
|
New electrically conducting composite polymers consisting of poly (2- hydroxy-5-methyl anline) self-doped with poly (o-toluidine) were prepared within the polymer matrix by in situ polymerization of aniline. the conversion yield of self-doped poly[2-hydroxy-5-methyl anline-co-(o-toluidine)] into doped poly[2-hydroxy-5-methyl anline-co-(o-toluidine)] by treatment with hcl while structural confirmation of the synthesized polymer was sought by fourier transform infrared and thermogravimetric analysis. conductivity of the polymers was measured by two probe method. as for activation energy, ea for dc conduction was deduced and its value was found to be the fraction of an ev for all the polymers. by increasing doping content, ea decreased and σ increased. the result showed that the conductivity increased with increasing temperature in the order: doping p(ot-co-hma)> p(ot-co-hma)> phma >pot, showing conducting behavior and activation energy of polymers was estimated.
