Abstract:
As a result of inherent rigidity of the conjugated macromolecular chains resulted from the delocalized π-electron system along the polymer backbone, it has been a huge challenge to make conducting polymer hydrogels elastic by far. Herein elastic and conductive polypyrrole hydrogels with only conducting polymer as the continuous phase have been simply synthesized in the indispensable conditions of 1) mixed solvent, 2) deficient oxidant, and 3) monthly secondary growth. The elastic mechanism and oxidative polymerization mechanism on the resulting PPy hydrogels have been discussed. The resulting hydrogels show some novel properties, e.g., shape memory elasticity, fast functionalization with various guest objects, and fast removal of organic infectants from aqueous solutions, all of which cannot be observed from traditional non-elastic conducting polymer counterparts. What's more, light-weight, elastic, and conductive organic sponges with excellent stress-sensing behavior have been successfully achieved via using the resulting polypyrrole hydrogels as precursors.Keywords:

Conducting polymer is a used material for many purposes, including active compound of chemical sensor. Polypyrrole, one type of conducting polymers, is frequently used because of its advantages, namely owing high conductivity, strong mechanical properties and relatively stable compound. This research was aimed to develop an alcohol sensor based on polypyrrole. Electropolymerisation of the polypyrrole was carried out using cyclic voltammetric technique. This research investigated some parameters electropolymerisation, namely variation of dopant electrolyte concentration, potential scan-rate, surface morphology of the polymer resulted, characteristic of the sensor performance when exposed to some alcohol compounds. According to the result of investigation, it was found that variation of potential scan-rate and dopant concentration has significant effect to the electropolymerisation process as well as to the resulted polymer, as indicated by the voltammogram profiles, the surface morphology of the resulted polymer and the response of resistance change of the polymer when exposed to the alcohol compounds.Keywords: polypyrrole, conducting polymer, alcohol sensor, cyclic voltammetry, electropolymerisation.

Polypyrrole is one of the most widely used and studied electroactive polymers due to its good conductivity and stability in air. A variety of low molecular weight and polymeric ions have been used as charge compensating dopants in conductive polypyrrole in its oxidized state. In this work we report the electro-polymerization of polypyrrole films incorporating electroactive N-substituted polyaniline polyelectrolytes as dopant ions.

Deformations of conducting polymer films, such as polyaniline, polypyrrole and polythiophene, induced by electrochemical oxidation and reduction are presented and discussed in terms of the mechanisms. Soft actuators with variety of motions such as bending stick, breathing ring and shouting lip utilizing polypyrrole films are demonstrated. A new operation method is proposed using electrodeposited polypyrrole films.

Conducting polymers have been studied extensively because of the fundamental interest and the potentiality in practical applications. An outstanding property of the polymers is that the conductivity of some of them, such as polypyrrole (PPy), polyaniline and so on, is affected by the applied voltage. For the polypyrrole, the oxidized state is of an electronic conductor and the reduced state is essentially insulating. Using this property, the
