This study prepared PEDOT/Carr aqueous dispersion in 1:1 ratio by weight as a conductive green polymer. PEDOT/Carr (1:1) dispersion was succesfully synthesized by oxidative polymerisation via in-situ and post-polymerisation reaction. The effect of base solutions or pH is very interesting to investigate on physicochemical of carrageenan doped with PEDOT. Processable conductive PEDOT/Carr dispersion needs to be investigated to optimize the properties of the film.]]> Fri 04 Nov 2022 09:59:34 AEDT ]]> End-capping of conductive poly(3.4-ethylene)dioxy-thiophene chain using 2-thienylmethyl methacrylate monomer https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:45732 2S2O8 and Fe2(SO4)3 as oxidation agents. The reactions performed using ratio EDOT:PSS of 1:2.5, with the addition of varying concentrations of end capping agent: 10%, 20%, 30%, 40% and 50% by weight with respect to the EDOT monomer. Chemical characterisations of the structures were analysed using NMR and FTIR. PEDOT/PSS dispersions were also analysed using dynamic light scattering (DLS), capillary electrophoresis (CE), scanning electron microscopy (SEM), and conductivity measurements using the four point probe method. The results showed that the end-capping PEDOT was successfully employed using 2TMM monomer. The higher ratio of end-capping agent resulted in smaller PEDOT as indicated by CE and DLS results. Films surface were smoother with an increase in the ratio of end-capping monomer. While the conductivities of the films decreased with an increase in the ratio of 2TMM monomer.]]> Fri 04 Nov 2022 09:59:25 AEDT ]]>
