Micro-ELECTROACTIVE POLYMERs have wide applications from industry to healthcare. Artificial muscles, microvalves, microswitches, haptic sensing, blood pressure and pulse monitoring are some potential applications for micro-ELECTROACTIVE POLYMERs. The most advantage of micro-ELECTROACTIVE POLYMERs as sensors and actuators is bio-compatibility and low power threshold for large deformations. In this short review, some applicable fabrication methods of micro-ELECTROACTIVE POLYMER cantilever are reviewed. Furthermore, a novel method based on standard micro fabrication techniques is designed and discussed in details which presents a conceptual design of a micro-ELECTROACTIVE POLYMER cantilever on a POLYMERic anchor located on a silicon substrate for future works.

Electrooxidation of β-naphthylamine (β-NA) in different aqueous acid media was investigated. The formation of a film adhered to the electrode surface was observed as a principal product and for which a POLYMER structure through C-N coupling is proposed. A standard three-electrode electrochemical cell was used for voltammetric experiments. In this system, glassy carbon rod, platinum wire, and KCl/saturated Ag/AgCl were used respectively as the working, counter and the reference electrodes. From the analysis of the voltammetric and spectroscopic experiments some aspects of the mechanism of electrooxidation of β-NA leading to the formation of the film was proposed. The effects of various physical and electrochemical parameters such as type of supporting electrolyte, temperature of the cell, pH, concentration of the monomer, scan rate and the number of scan cycles were studied. The electrochemical behavior of the film was reported as a function of these parameters. A quasireversible behaviour was observed from cyclic voltammograms obtained in different acid solutions. The film behaved as a thin-layer cell when it was obtained at low scan rates and dilute solutions of the monomer.

Many attempts have been made in the last decade to improve the solubility and processability of polyaniline (PANI) and various procedures have been devised in this direction, such as coPOLYMERization, "precursor", "composite" and emulsion methods. It seems that the presence of an electron withdrawing group or an electron donating group decreases orbital overlap of the π-electrons and the nitrogen lone pair and leads to enhancement of solubility and processability of PANI. NPhenylglycine (PG) has a similar structure to aniline, but it has a carboxyl group at the site of nitrogen. POLYMERization of PG in presence of template results in a water-soluble, conducting POLYMER. A strong polyelectrolyte acid such as sulphonated polystyrene (SPS) is the most favourable template. Poly (N-phenylglycine) (PPG) was prepared by the chemical method using ammonium persulphate (APS) as an oxidant in the presence of SPS as a template. The product was characterized by Fourier transform infrared (FTIR) and the ultraviolet-visible (UV-vis) spectroscopy. Cyclic voltammetry studies showed only one set of redox peaks and redox reversibility demonstrated the electroactivity of PPG as well. The electrical conductivity of POLYMER was measured by four-point probe method. The results showed that POLYMER yield and conductivity decrease as the ratio of template to monomer increases.

Introduction: The initial spark of nanotechnology goes about half century. There is a lot of space in the low levels. Molecules and atoms are subject to change and new behaviors are expected of them. Nano POLYMERs and nano composites are a part of nano materials. They are especially important because many applications have. Conductive POLYMERs such as polyaniline have interesting properties, conductivity, optically and electro activity. Numerous applications of this nano POLYMERs and its composites can be visitor including electronics, sensors, protections of electrodes, absorption and transfer of heavy metals and removal of organic dye from solutions. Polyaniline protonated state has a good conductivity, but poor mechanical properties. The production of composite by polyaniline and polyamide POLYMERs such as insulation, and using the common solvent can be added to its mechanical properties.Aim: Synthesis of polyaniline and nano conductive POLYMER composite with the insulating POLYMER to increase mechanical properties, and study of electrical properties, thermal of Pan/Ny66.Materials and Methods: At this stage, polyaniline synthesis by oxidation with ammonium persoulfate. The electrical properties of Pan/Ny66 nano composite were analyzed by 4-point probe technique. UV-Vis Spectroscopy was used for thermal stability study. The tensile strength test was used to evaluate the mechanical and stability properties. Surface morphology changes were evaluated by scanning electron micrograph (SEM) before and after the production of composite.Results: Polyaniline procces due to poor mechanical properties and low strength of its disadvantages is considered. There is no study thermal stability and electrical conductivity under such conditions. Using formic acid as a common solvent for polyaniline and nylon66, Pan/Ny66 will provide by casting method.1 to 2 ratio of polyaniline to nylon66, is sealed. The thermal stability is high by composite production. Electrical conductivity increases in the Pan/Ny66 composite.Conclusion: Casting method is used for the preparation of nano composite films. Using this method, increased on mechanical properties, thermal stability and electrical conductivity.
