Deadline for manuscript submissions: closed (31 May 2021).
Interests: multifunctional composites; structural health monitoring; strain sensor; damage monitoring; graphene nanoplatelets; carbon nanotubes
Interests: Manufacturing and behavior characterization (mechanical, electric and thermal) of multifunctional composite materials (carbon fiber, thermosetting resins) by the incorporation of nanoparticles (carbon nanotubes and graphene nanoparticles)
In the last few decades, the development of structural health monitoring systems has attracted the interest of industry. Strain sensors based on carbon nanoparticles, such as carbon nanotubes, are increasingly being thought of as a realistic alternative to conventional sensors based on metallic and semiconducting materials, largely due to their superior electrical properties. The addition of carbon fillers to polymer matrices allows the formation of an electrical network that gives the material a high piezoresistivity.
These doped polymer matrices can be manufactured in different forms, such as flexible sensors that can be attached on a substrate, conductive adhesives that can detect crack propagation along bonded joints, etc. Another possibility is to use these matrices in fiber-reinforced polymers for the detection of failure. In this case, the incorporation of carbon nanofiller could also be used in the creation of a coating on traditional fiber fabrics for strain/damage monitoring of the composite material.
This Special Issue of Nanomaterials will attempt to cover the recent advances in carbon nanoparticles for strain and damage sensor applications, including the analysis of electrical conductivity and piezoresistivity of carbon nanoparticles/polymer nanocomposites, the relationship between them, the tunneling effect, sensitivity to different load modes, theoretical and numerical studies, 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. 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 2200 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.
