| Summary: | 碩士 === 國立臺北科技大學 === 有機高分子研究所 === 101 === The study is based on tetraaniline synthesized by using dianline as monomer and FeCl3 as a oxidant. However, tetraaniline are commonly classified as rigid, brittle, and difficult to process. And experiment method is to flexible macromolecules such as PU into conjugated polymer to make polymer composites.
The prepolymer was reacted by ether-type poly(tetramethyleneglycol)(PTMO) as soft segments and 4,4-diphenylmethane diisocyanate (MDI) as hard segments with molecular weight 2900 and 250 respectively. Then the tetraaniline could connected end to end in two short of the prepolymer to form copolymers. The copolymer could be as some Nano sliverwire or graphene as addition agent while the copolymer dissolve in DMF.
The structures of nanocomposites chemical were investigated by FTIR spectra and MS. The analyze the microstructure were by SEM and TEM. The physical properties of nanocomposites were investigated by DMA, Four-point probe, and XRD. The experimental results is Nano silverwires content of 3% in the copolymer, the best conductivity for 3.60*10-2S/cm. However, stretch molecular chain in nanocomposites is orientation as the increase in conductivity.
