Special Issue Information

Dear Colleagues,

Composites are engineering materials that benefit from the synergy of combining the physical properties of a matrix and the reinforcement. This feature allows researchers to design and tailor the behavior of composite materials for specific engineering applications. One of the fields that strongly benefits from this is the electrical sector. It is well known that most materials in electrical components are subjected to a complex combination of potentially-damaging loads (i.e., electrical, thermal, mechanical, chemical), which compromise their ideal performance and might severely reduce their duty life. To overcome this, a complex combination of physical properties are required from the material. It is already known that pure metals or alloys rarely present this combination, thus severely restricting their application range. Hence, the most suitable approach is by the use of highly-engineered composites.

The scope of this Special Issue covers the new approaches to the use of composite materials in electrical applications, like for instance electrical contacts, plug connectors, electrodes, but also sensors. The focus of the submitted manuscripts may be placed on:

  • Design and manufacturing of different composite systems (multilayers, metal matrix composites, polymer matrix composites, pseudoalloys, carbon-based materials, etc.).
  • Advanced characterization (microstructural, physical properties, etc.).
  • Modelling and/or simulation.
  • Prototype performance (contact resistance, make/break operations, friction and wear analysis, sensing response, durability, etc.).

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. Journal of Composites Science is an international peer-reviewed open access quarterly 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 1000 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.

The detection of dopamine, an important neurotransmitter in the central nervous system, is relevant because low levels of dopamine can cause brain disorders. Here, a novel electrochemical platform made of a hydrogel–graphene oxide nanocomposite was employed to electrochemically determine simultaneously dopamine (DA) and ascorbic acid (AA). Unlike previous work, where the base electrode is modified, the active material (graphene oxide, GO) was dispersed in the hydrogel matrix, making an active nanocomposite where the electrochemical detection occurs. The GO, hydrogel and nanocomposite synthesis is described. Dynamic Light Scattering, UV-visible and FTIR spectroscopies showed that the synthesized GO nanoparticles present 480 nm of diagonal size and a few sheets in height. Moreover, the polymer swelling, the adsorption capacity and the release kinetic of DA and AA were evaluated. The nanocomposite showed lower swelling capacity, higher DA partition coefficient and faster DA release rate than in the hydrogel. The electrochemical measurement proved that both materials can be employed to determine DA and AA. Additionally, the nanocomposite platform allowed the simultaneous determination of both molecules showing two well separated anodic peaks. This result demonstrates the importance of the incorporation of the nanomaterial inside of the hydrogel and proves that the nanocomposite can be used as a platform in an electrochemical device to determinate DA using an unmodified glassy carbon electrode.
