Magnetic-Responsive Molecular Particles Based Smart Materials: Model, Characterization and Applications

Dear colleagues,

Magnetorheological (MR) materials are one of the best candidates to fulfil the scope of controllable discrete devices and smart structure that react to the magnetic field. This is possible due to the chain-like structures of molecular nano- and micro-sized particles with respect to the magnetic field direction. The field-dependent properties of MR materials such as the viscoelastic modulus can be tuned by the magnetic field intensity and hence the performance of application devices can be easily controlled by implementing appropriate controllers those can provide an optimal magnetic field intensity to achieve desired responses. Thanks to this salient and eminent feature, MR materials are widely applied to numerous fields such as automotive shock absorber, vibration isolator, flexible haptic structure and so on. In general, MR materials are divided into 5 categories including MR fluid, MR grease, MR elastomer, MR gel and MR foam. They are different in terms of the physical appearances like liquid, semi-liquid, solid and semi-solid. Thus, the field-dependent properties of each MR material are different and application fields are specialized.

The followings are the topics proposed for this special issue (but not limited to):

• Molecular model of MR materials
• Modelling and simulation of MR materials behaviors
• New formulation of MR materials
• Materials selection of MR materials
• Properties and characterization of MR 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 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 250 words) can be sent to the Editorial Office for assessment.

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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.
