  • Polypyrrole (PPy) is regarded as one of the most Promising intrinsically or naturally conductive polymer for practical applications due to its relatively high electrical conductivity, environmental stability and low toxicity. The typical PPy, which is insoluble and infusible, exhibits poor processability and lacks essential mechanical properties. A number of papers have concerned the efforts to overcome these drawbacks.

  • 전도성 고분자(conductive polymer)는 범용 고분자에 비해 우수한 전기적 특성을 지니는 반면, 가공이 난이하다는 단점을 가진다. 이러한 전도성 고분자의 최대 단점인 가공성의 개선을 위한 방법으로는 새로운 전도성 고분자를 합성해 내거나 화학적 개질인 공중합(copolymerizaon)이 가능하고, 물리적인 접근법으로 블렌드와 복합재료화가 가능하다. 일반적으로 널리 쓰이는 것은 블렌드와 복합재료화를 통한 물리적 접근법인데 이는 기존의 물성을 그대로 가지면서도 제조가 비교적 용이하기 때문이다. (중략)

  • Electrically conductive polymer nanocomposites were prepared by the inclusion of graphene-based nanofillers. Graphene oxide (GO) and reduced graphene oxide wrapped by poly(styrene sulfonate) (PSS-RGO) were used as nanofillers to make good dispersion with the aqueous dispersion of polystyrene (PS) particles. GO sheets were synthesized by the modified Hummers' method from graphite, and PSS-RGO sheets were prepared by the reduction of GO-dispersed PSS solution with hydrazine monohydrate. Morphology and properties of PS/GO and PS/PSS-RGO nanocomposites via latex technology were investigated. Both nanofillers showed well dispersed morphology in PS matrix. Rheological and electrical percolation thresholds were 0.28 and 0.51 wt% for GO, and 0.50 and 1.01 wt% for PSS-RGO respectively. It is speculated that PS/GO nanocomposites showed better conductivity than PS/PSS-RGO counterparts due to the partial recovery of GO by thermal reduction during molding.

  • This study introduces a facile strategy to prepare metal oxide/conducting polymer nanocomposites that may have promising applications in energy storage devices. Ploy aniline/nano wire manganese dioxide (PANI/NwMnO2) was synthesized by cyclic voltammetry on glassy carbon electrode. Morphology and structure of the composite, pure PANI, MnO2 nanowires were fully characterized using XRD and SEM analysis. Electrochemical studies shows excellent synergistic effect between PANI and MnO2 nanowires which results in its capacitance increase and cycle stability against PANI electrode. Specific capacitances of PANI/NwMnO2 and PANI were 456 and 190 F/g respectively. The electrochemical performance of electrodes studied using cyclic voltammetry, Galvanostatic charge/discharge and impedance spectroscopy.

  • The fuel cell which converts directly chemical energy of fuel into electric energy has higher efficiency than the conventional power generation which involves several additional processes. Especially, polymer electrolyte membrane fuel cell (PEMFC) of which the electrolyte is a thin proton conductive polymer membrane is affordable for portable power applications and small-scale distributed power generation including household and small building. It is very important to not only increase the efficiency of FC itself but determine the optimal operation mode. The optimal operational planning of lkW household PEMFC system based on the daily electricity and heat demand patterns was performed. The estimated economic gain was up to 20% by adoption of PEMFC system.

  • Polyphenylenediamine(PPD)film was prepared with organo sulfur compond (2-aminothiophenol, 1,2-ethanedithiol, and 2-aminoethaneethiol etc.) adding lithium salt to increase the electrical conductivity of the polymer surface. The molecular structure of conductive polymer synthesized were examined and discussed by using SEM, FT-IR, NMR etc. The elecrical conductivity messurement were carried out with four-probe method at dry box of He and $N_2$atmosphere. The typical value of successful electrical conductivity was 1.2$\times$10$^1$S/cm at room temperature.

  • In aqueous phase, we directly prepared conducting and photoluminescent nano-structured particles by oxidation polymerization. Thiophene(PT) was initiated by $FeCl_{3}/H_{2}O_{2}$ (catalyst/oxidant) combination system. And, polydispersed core-shell poly(styrene/thiophene) and polyaniline(PANI)-coated multi core-shell polystyrene latex particles were successfully prepared by oxidative and radical polymerization. The resulting latex particles have fine improved luminescence and conductive efficiency and dispersion state due to the PT and PANI shell. Hyper functionalized nanoparticle would be expected to increase the processibility in various electrical and electro-optical fields.
