We synthesised a polyaniline/mica (Mica–PANI) nanocomposite using naturally occurring muscovite mica by a top-down approach. The developed coating materials were characterised using a different technique to investigate their chemical and structural properties using Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning el...

Mica is a relatively abundant mineral found on earth’s crust and is used in various industries such as paint, construction, electronics, water sciences and so on, due to various properties including softness, lightness, chemical inertness, thermal and electrical stability. This study is an attempt to showcase the potential of value addition to musc...

Sri Lanka is well endowed industrially important sheet silicate mineral namely mica. Polyaniline (PANI) is also recently gained attention as conductive polymers in the application of the anticorrosive protective coating on the surface of metals. Mica has achieved its interest due to its two dimensional sheet silicate structure and it exhibiting pro...

chapter reviewed some advancements on utilization of nanoparticles and nanomaterials to reinforce ceramic matrices. Nanomaterials and nanoparticles such as alumina, zirconia, titania, carbon based materials, rare earth oxides, hydroxyapatite and metal nanoparticles have been widely used in reinforcement of ceramic matrices. Such nanomaterials are u...

Thin films of akaganeite [FeO(OH)] nanorices deposited muscovite mica (ANPM) surfaces are synthesized using the facile urea assisted controlled self-assembly technique. The synthesized materials are characterized using scanning electron microscopy (SEM) with energy-dispersion X-ray spectroscopy, atomic force microscopy, X-ray diffraction (XRD), Fou...

Industrially important mica mineral deposits are widespread in many parts of Sri Lanka such as Matale, Talatu Oya, Badulla, Maskeliya, Halmadulla, Kabitigollawa and Balangoda. However, industrial applications of mica minerals in Sri Lanka are limited to production of paints, plastics, lubricants and traditional medicinal ingredients even though the...

Naturally Eppawala Rock Phosphate (ERP) contains a high concentration of iron baring gangue mineral such as magnetite and, is suffering with the ineffective availability of phosphorous contents. Though, many of chemical and physical purification methods have been introduced, bio leaching has been identified as an effective and an ecofriendly techni...
