Polyaniline-Copper Oxide Nano-Composites: Synthesis …

Polymer nanocomposites with practically all the commercial polymer matrices have been synthesized and nano-scale filler dispersion has been achieved with varying degrees of success. The commercial polymer nanocomposites studied to a great extent are unfortunately non-biodegradable like polyethylene, polypropylene and polystyrene etc. To a small extent, these nanocomposites are reformed or recycled into other products after one life cycle, however, the properties of such recycled materials are very poor. Therefore, subject of bio-based nanocomposites and biodegradable nanocomposites has become topic of interest in the recent years and a number of suitable bio-based and biodegradable polymer matrices have been developed and their property enhancement have been reported after the incorporation of the inorganic filler materials. These systems include poly(lactic acid), poly(butyl succinate), alginate, cellulosic plastics, gelatine, starch, soy protein based polymers, plant oil based polymers, poly(hydroxyalkanoates), bio based epoxies, etc. Various inorganic filler systems like clay, spherical particles as well as nanotubes have been incorporated in these matrices. The various properties which have been enhanced include mechanical performance, thermal properties, gas diffusion resistance, flammability, rheological performance, biodegradation etc. Though the commercial applications of these bio-nanocomposites are in infancy, but these materials have a huge commercial potential. The book provides the description of the subject as a whole, from the basic introduction to the more specific systems and advancements. The use of such nanocomposites for packaging as well as for sensors has been depicted.

Nanocomposites: synthesis, structure, properties and new application opportunities

The nanocomposites of polyaniline (PANI) and carboxylated multi-walled carbon nanotubes (MWCNTs) were synthesized by in situ chemical oxidative polymerization method using HCl as a dopant and Ammonium persulphate (APS) as an oxidant. The MWCNTs were carboxylic functionalized and were ultrasonicated to obtain uniform dispersion within the PANI matrix. Field emission scanning electron microscopy (FE-SEM) was used to characterize the morphology of the nanocomposites. X-Ray diffraction (XRD), Fourier Transform Infrared (FT-IR) spectroscopy, Raman spectroscopy and UV-Vis spectroscopy were used to characterize the synthesized PANI-MWCNT nanocomposites. It was found that in situ polymerized PANI layer matrix was formed on carboxylated MWCNT and there was uniform dispersion of MWCNTs within the PANI matrix with significant interaction between PANI and MWCNTs. The electrical conductivity of composites at room temperature was measured and their percolation threshold briefly discussed.

LPCM is an interdisciplinary research group whose activities focus on the design, synthesis, characterization and processing of polymer materials. Effective member of the Center of Innovation and Research in Materials and Polymers (), Dubois’ group has developed scientific and technological skills allowing a step-by-step follow up of the materials from its conception to its fate. LPCM takes advantage of its expertise in macromolecular engineering and polymer processing to design well-defined materials while its equipment facilities offer in-depth characterization and better understanding of resulting properties. LPCM research activities have been organized in 4 research subgroups closely interconnected to each other with research activities spanning the development of new synthetic strategies as well as novel polymers or polymer materials for applications in energy, health and biomedical sciences, sustainable and (nano)composite materials.

Polymer nanocomposites, polymers that are reinforced with nano-sized particles, provide enhanced mechanical, thermal, electrical, and barrier properties. Continued research and development of new polymer nanocomposites promises to provide enhanced materials to a broad range of industries, such as plastics, aerospace, automotive, electronics, packaging, and biomedical devices. Structured as a practical laboratory manual, this book enables readers to expertly synthesize and characterize metal-polymer nanocomposites by clearly setting forth the principles and techniques.
