Polyaniline/clay nanocomposites. A comparative approach on the doping acid and the clay spacing technique

Effect of Clay Loading in the Morphology and Electrical Conductivity of Polyaniline-Clay/Elastomer Semiconductors

“…The electrical conductivity of PCNs and PCEs was measured with a HP Agilent Multimeter 34401 and a Keithley 6517A electrometer, respectively, by using a 4-probe device. (Figure 1.a) consists of 50-100 nm thick nanofibers, as already reported [1]. The presence of clay does not produce a significant effect on PAni morphology at any clay/aniline ratio (Figure 1.b-e) since PCNs keep the nanofiber structure trend.…”

“…Polyaniline (PAni) has ranked as one the most studied conducting polymers due to its outstanding combination of chemical nature, high electrical conductivity, environmental stability, harmlessness, ease of preparation and low cost. These attributes have positioned PAni in a wide range of applications such as rechargeable batteries, EMI shielding, microwave absorption, capacitors, electrochromic devices, electromechanical actuators, anticorrosion coatings and sensors [1]. Also, PAni has been considered as a viable alternative to replace metals as electrically conductive fillers in the production of semiconducting elastomers [2].…”

“…PAni-clay/elastomer materials are prepared by a two-step procedure: first, the synthesis of PCNs by in situ oxidative polymerization of aniline in the presence of clay [1] modifying clay/aniline ratio, and then, the preparation of PCE by mechanical mixing of PCN with SEBS (Dynasol) employing a Brabender Intellitorque mixing chamber, keeping a 20:80 PCN:SEBS ratio. PCNs morphology was analyzed by using a JEOL JSM-7401F equipment.…”

Properties of natural mineral/polyanilyline composites doped by sulfuric acid

“…Композитні матеріали (КМ), утворені з природних мінералів (мінеральних глин) та ПАн, усе частіше застосовують [13][14][15][16]. Наявні в композитах ПМ, завдяки їхнім хімічним та морфологічним особливостям, надають КМ нові функціональні властивості [17,18] та слугують матрицями-носіями ПАн [13], що значно розширює межі їхнього застосування.…”

Organo-montmorillonite modified by polyionenes for polymer composites

“…The global miniaturization trends testify the science and technology objects to be decreased up to nano-size through the depletion of miniaturization possibilities via the traditional technologies [1][2][3] Nano-phase materials science differs from the traditioanal materials science by working-out of innovative materials. The functional parameters of mentioned materials being defined not only by microdomain properties but processes as found to be on atomic and molecular level in monolyaers and nanovolumes [4][5][6][7] Respectively, the modeling of processes of materials conversion dealt filled with fine particles is focused on determining of particles-aggregates interaction energy.…”
