the second monomer is 1

4-dibromobenzene and p-quinine demine with a Ni (Ⅱ) catalyzed synthesis of different proportions poly (1

4-benzoquinone demine 1

3-dibromobenzene bromophenyl) random copolymer. Test methods and by infrared spectroscopy (FT-IR)

ultraviolet-visible absorption spectroscopy (UV-Vis)

X-ray powder diffraction (XRD)

thermal gravimetric analysis (TG)

cyclic voltammetry (CV)

charge and discharge of the copolymer characterization and performance tests conducted to study the effects on performance copolymer linked site. UV-visible absorption spectra showed a maximum absorption peak at 490nm appeared around the copolymer

P2

P5 and P1 in the absorption peak at this wavelength

respectively

compared red shift 10

24nm

wherein the copolymer P4 red shift of 34nm

has a high degree of conjugation; temperature reached 671℃ copolymer P2 was decomposed 40%

P1 when the temperature reached 577℃ decomposed 40%; cyclic voltammetry indicated that P1 to P4

the copolymerization peak area was gradually began to become larger

the greater the peak area

the greater the ratio of the capacitance of the copolymer to the peak area at the beginning of the copolymer P5 becomes smaller; discharge copolymer P4 show the longest discharge time

begins to increase from P1 until P4

P5 into the copolymer begins to decrease the discharge time.
