Actuators Based on Two-Dimensional Materials

Dear Colleagues,

Two-dimensional (2D) materials have many superior properties, which are quite different from those of conventional three-dimensional (3D) materials. For example, they have an ultra-high Young modulus, negative coefficient of thermal expansion, flexibility and high mobility of graphene, which can enable novel actuators with new functionalities. This Special Issue is aimed at taking advantage of 2D materials, with a particular emphasis on the actuator: 2D material-based actuators. These actuators can be built in many difference ways (such as mechanical exfoliation, chemical vapor deposition, chemical solution production). One such method is using 2D materials themselves as actuators. The 2D materials can be also combined with other materials to form 2D mixtures/polymers. Another way to build 2D materials based actuators is by inserting 2D materials into conventional 3D actuators, serving as interface layers or electrodes. The movement of a 2D actuator can be at the nanoscale, microscale, or macroscale. The 2D material-based actuators can be driven by many ways (such as thermal gradient, electrical signal, light, and magnetic field). Either enhanced performance or new functionalities are particularly encouraged for this topic.

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 submissions that pass pre-check are 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. Actuators 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 2400 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.
