Direct synthesis of conducting polymers from simple monomers

Voltage Effect in Holograms of Polyvinyl Alcohol with FeCl3

“…PVA (aq) and FeCl 3(aq) are combined in a ratio 10:2 and 10:5, at 25 °C, with conventional drying of samples C and F for 24 h at normal laboratory conditions. Starting here, the intramolecular interaction of components [18,19] ], with the production of ferrous chloride (FeCl 2 ), ferrous hydroxide, Fe(OH) 2 , ferric hydroxide, Fe(OH) 3 , hydrogen gas, H 2 , and chlorine gas, Cl 2 , [53,[68][69][70][71][72][73][74][75] this process darkens the sample film. Lastly, the photo-electrochemical process is performed by a redox reaction.…”

The Electrochemical Synthesis and Corrosion Inhibitive Nature of Di N-Propyl Malonic Acid Doped Poly N –Methyl Aniline Coating On Stainless Steel

“…The emerladine salt has low electrical conductivity and it can be improved by doping with various protonic acids [22]. Numerous oxidant systems including transition metal salts were reported for the chemical polymerization of aniline (ANI) [18]. In particular, polymerization of ANI can be conventionally achieved by using (NH4) 2 S 2 O 8 /HCl as the oxidant system [23].…”

“…There are mainly two routes for the preparation of CPs: chemical and electrochemical polymerization [18,19]. Barring direct formation of films of various CPs in electrochemical polymerization, chemical oxidative polymerization has also attracted much attention because of the cost-effective production in the latter system [18]. Among various CPs, PANI is unique in nature from the viewpoint that its electrical behaviour can be reversibly controlled by charge-transfer doping and by protonation and it has a good environmental stability [20].…”

Szerkezeti tényezők hatása a vezető polimerek termoelektromos tulajdonságaira

“…[23,26,27] Előbbit többnyire akkor alkalmazzuk, mikor a vizsgálatokhoz vagy a felhaszná-láshoz nagyobb mennyiségű anyagra van szükség, míg utóbbinak a redoxi tulajdonságok, a spektrális átalakulások, az elektromos vezetés változásának vizsgálatakor, valamint módosított elektródként történő alkalmazáskor jut fontos szerep. [28] Kémiai polimerizáció során a monomert valamely megfelelő redoxi potenciállal rendelkező anyag, legtöbbször valamilyen Fe(III)-vagy peroxo-diszulfát ionokat tartalmazó vegyület alkalmazásával oxidáljuk. [29] Fontos megemlíteni, hogy a klasszikus, iniciált polimerizációtól eltérően itt minden egyes monomer két elektron (és két proton) leadásával oxidálódik, így megőrizve a konjugált elektronrendszert a kialakuló polimerben is.…”
