Polymer Nanocomposite Processing, Characterization, and Applications, 2011": Special Issue of Journal of Nanomaterials

I would like to call your attention to a special Issue (focus) on "Polymer Nanocomposite Processing, Characterization, and Applications" scheduled to be published in the Journal of Nanomaterials in December 2011. For the second time a special issue of the Journal of Nanomaterials will be devoted to emerging polymer nanocomposite processing techniques and call for new contributions in the field of characterization and applications of multifunctional nanocomposites. The Call for Papers can also be viewed at the journal website at http://www.hindawi.com/journals/jnm/si/pnca11/ . The deadline for manuscript submission is June 15, 2011.

Please note that the Journal of Nanomaterials is an open access journal, which means that all published articles are made freely available online without a subscription, and authors retain the copyright of their work. If you have any questions about this Special Issue, or about the journal, please do not hesitate to contact me or another Guest Editor given below.

Hi Tanil,

 

Thanks for your comment.

 

This special issue intends to cover the entire range of basic and applied materials research focusing on processing, rheological characterization, nanoparticle dispersion, and functional properties of polymer nanocomposites for sensors, actuators, and other applications. While a number of advances have been made in the area of polymer nanocomposites, the studies on understanding of the effects of processing parameters on the morphology, and multifunctional properties of polymer nanocomposites are deficient. For example, during industrial processing the polymer nanocomposites undergo a complex thermo-mechanical history during which the macromolecules undergo rapid shear and extension followed by rapid quenching. The processing parameters such as pressure, shear deformation, stretching affect the structure, crystallization behavior as well as properties of the semicrystalline polymers. The presence of nanoparticles in these polymers can further affect the crystallization kinetic as well as morphology while undergoing deformation. All these factors define and control the overall properties of the semicrystalline polymer nanocomposites. Nanoparticles orientation, their state of dispersion within the matrix, interaction between the polymer chains and the nanoparticles are some of the other factors which also affect the properties of these nanocomposites.

Hello Dr. Mago,

Thanks for your recent update concerning the focus of this special PNCA issue. As you emphasized, the macroscopic mechanical response and multifunctional  properties of polymer nanocomposites are effectively determined by processing conditions and their thermo-mechanical history. For this class of materials, in many cases beneficial synergistic interactions have been observed with composite level tests, exceeding certain physical expectations based on scale-specific properties of individual constituents. The example which you mentioned concerning rapid shear and quenching of macromolecular chains is what we hypothesize as being the primary mechanism responsible for a supra-hierarchical arrangement and concurrent confinement effects in the so-called interphase region in the vicinity of some nanoscale inclusions, leading to significant mechanical property improvements compared to the bulk scale polymer. As the focus suggests, this special issue appears to become an extremely useful and timely piece of literature for the entire polymer nanocomposites community. Thanks again for your efforts in organizing this.

 

Best wishes,
