Special Issue Information

Dear Colleagues,

Decreasing the size of materials to the nanometer scale always leads to the appearance of new specific properties, due to the major impact of the surface and quantum effects. In the case of mechanical properties, the downsizing often leads to the stiffening of the structure which opens perspectives to design new nanocomposite materials with unique characteristics. Nanocomposites offer an exceptionally extensive range of prospective ways of application, from electronics to biology, which allows to consider them as the XXI century materials. Physical and chemical properties of a nanocomposite are sufficiently different from those of the component materials and they are determined by the same factors as usual composites, i.e., component properties, composition, structure, and interfacial interactions. However, their impact is more sensitive due to the nanoscale size of its constituents and it is more challenging to control them. Fundamental studies of mechanical, electrical, thermal, optical, and chemical properties are required along with a thorough research for the real application.

The titled Special Issue aims to cover current experimental and/or computational studies in the field of nanocomposites. The focus of this Issue is to highlight the state of knowledge in processing, manufacturing, characterization and potential application for the new nanocomposite materials.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Nanomaterials is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2000 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

This paper deals with the electrochemical characterization and the equivalent circuit modeling of screen-printed electrodes, modified by an epoxy composite and loaded with carbon nanotubes (CNTs), pristine and functionalized NH2, and graphene nanoplates (GNPs). The fabrication method is optimized in order to obtain a good dispersion even at high concentration, up to 10%, to increase the range of investigation. Due to the rising presence of filler on the surface, the cyclic voltammetric analysis shows an increasing of (i) electrochemical response and (ii) filler concentration as observed by the scanning electron microscopy (SEM). Epoxy/CNTs-NH2 and epoxy/GNPs, at 10% of concentration, show the best electrochemical behavior. Furthermore, epoxy/CNTs-NH2 show a lower percolation threshold than epoxy/CNT, probably due to the direct bond created by amino groups. Furthermore, the electrochemical impedance spectroscopy (EIS) is used to obtain an electrical equivalent circuit (EEC). The EEC model is a remarkable evolution of previous circuits present in the literature, by inserting an accurate description of the capacitive/inductive/resistive characteristics, thus leading to an enhanced knowledge of phenomena that occur during electrochemical processes.
