Conducting nanostructures have achieved a prominent position in nanotechnology. Because of larger surface area it can be used in various applications. In recent scenario a class of conducting polymers is becoming popular due to its mechanical and electrical properties. Polyaniline is a conducting polymer which is popularly known as an environmentally stable and highly tunable polymer which can be produced in the form of bulk powder, cast films, or fibers. Polyaniline is of low cost, large-scale production, it is extensively used in vast applications. Polyaniline term corresponding to a class of polymers with up to 1000 repeat units (also known as MER) and was firstly it was known in 1862. Nanocomposite material is a solid phase multi-phase one of which has one, two or three dimensions less than 100 nanometers ( nm) , or structures having repeating distances nanoscale between the different phases within the material. Silica Nanocomposites combined with conducting polymers such as polyaniline are prepared by in situ polymerization and can be used in various applications such as supercapacitors, pseudocapacitors, Layerings and coatings, metal uptake, Chemosensors, Encapsulation of Organic Light Emitting Devices, Proton exchange membrane, pervaporation membrane, biosensors, flexible nanoelectronic devices, drug delivery.Keywords

The main motive behind this research is to eradicate the limitations of the conducting polymers and replace these materials with newly emerging materials known as 'Nano-composites' because of their superior electrical and mechanical properties. The various naturally occurring inorganic nanoparticles which arewhen combined with conducting polymers leads to the generation of a host of nanocomposites which has very fascinating properties as well asadequate application potential. In this paper,various fundamental materials along with their conducting properties that are employed for synthesis of nanocomposites such as nano materials and conducting polymers have been analyzed and discussed.The Graphene-based polyaniline (PANI) nanocomposites have been used in the proposed formation of hybrid material comprising of conducting polymer and carbon nano material. The Polyaniline/Graphen nanocomposites (PANI/G) are synthesized on the basis of graphene to polyaniline(PANI) ratio.The PANI is known for its low cost, good environmental stability, interesting electro activity, high pseudo capacitance which makes this material to be suitably employed for electronic, optical and electrochemical applications.Polyaniline/Graphene nanocomposites (PANI/G) aresynthesized at various loadings of graphene to polyaniline(PANI) ratio.Keywords

The present work describes a new, simple and environmentally friend procedure for preparing Silica/Polyaniline (PANI) hybrid materials by combining the sol-gel method and in situ polymerization of aniline. The synthesis of silica nanocomposites and Silica/PANI nanocomposites was done and their morphological and structural behavior characterization the Silica/PANI nanocomposite were examined under Scanning Electron Microscopy (SEM). For elemental ratio Scanning Electron Microscopy and Energy Dispersion Spectroscopy (SEM and EDS) was conducted which checks the content of individual elements in the sample, Fourier transform infrared spectra(FTIR) depicts graphs between transmittance ratio and wave number, various stretching between different functional groups and observed absorption bands ranges from 1636 to 3405 cm-1. It was also found that the conductivity of the sample gradually increases with the increase in voltage and current.Keywords

There is rapid growth of environmental pollution due the production of electrical and electronic products and their improper disposal. About 80% of e-waste from developed countries is illegally exported to developing countries because of the lower labor costs and lack of governmental regulations. The decreasing costs and increasing availability of electronic equipments like mobiles, televisions, computers and their accessories with advanced technology and the fast rate at which the outdated units are changed, has given rise to a new stream of waste known as Electronic waste (E-waste). E-waste contains two major types of substances: hazardous and nonhazardous both types have potential negative environmental impacts. It consists of various metals, metalloids, precious metals, halogenated compounds and radioactive elements. Metals and metalloids include Aluminium, Arsenic, Antimony, Barium, Beryllium, Cadmium, Chromium, Copper, Europium, Lead, Lithium, Iron, Manganese, Mercury, Nickel, Selenium, Silica, Tin, Yttrium, Zinc, etc. Precious metals include Gold, Indium, Silver, Palladium, Platinum, etc. Halogenated compounds like Polychlorinated Biphenyls (PCB), Tetrabromobisphenol (TBBA), Polybrominated Biphenyls (PBB), Polybrominated Diphenyl Ethers (PBDE), Chlorofluorocarbon (CFC), Polyvinylchloride (PVC) are present. Radioactive metal like Americium is found in the electronic scrap. This review article provides a concise overview current e-waste scenario.Keywords
