Special Issue Information

Dear Colleagues,

It is our pleasure to invite you to submit an article to this Special Issue of Nanomaterials, on the topic of “Advanced Nanomaterials for Flexible and Stretchable Electronic/ Optoelectronic Devices”.  Nanomaterials are materials with one or more dimensions falling into the nanometer scale. The dramatic size shrinkage renders them new electronic, magnetic, optical and thermoelectric properties. One of the most successful examples is colloidal semiconductor quantum dots (QDs) whose sizes are typically within several nanometers. With strong size-dependent spectral properties and narrow emission spectra, QDs have achieved great success in applications such as biological imaging, catalysis, and sensing. As modern society gradually steps into the intelligent age, nanomaterials will have broad application potential in a flexible display, electronic skin, wearable electronics, artificial nervous systems, human–machine interactions, etc.

This Special Issue will show the latest research progresses and challenges of nanomaterials developed for flexible and stretchable electronic/optoelectronic devices from the perspective of the material syntheses, device structures and applications. We encourage submissions on synthesis and design of functional nanomaterials (such as colloidal CdSe or InP QDs, perovskite QDs, etc.), and study of device engineering and device physics. In addition, applications of advanced nanomaterials in light emitting diodes, photodetectors, flexible batteries and wearable sensors are welcome.

All kinds of papers—research articles, letters, communications, and reviews—are welcome. We would like to thank the Nanomaterials Editorial Office for its encouragement and support. We would also like to thank all the authors for their valuable contributions and the reviewers for their valuable comments. This Special Issue would not have been possible without their contributions and encouragement.

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. Nanomaterials is an international peer-reviewed open access semimonthly 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 2900 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.

A flexible thermoelectric device has been considered as a competitive candidate for powering wearable electronics. Here, we fabricated an n-type Ag2Se/Ag composite film on a flexible nylon substrate using vacuum-assisted filtration and a combination of cold and hot pressing. By optimising the Ag/Se ratio and the sequential addition and reaction time of AA, an excellent power factor of 2277.3 μW∙m−1 K−2 (corresponding to a ZT of ~0.71) at room temperature was achieved. In addition, the Ag2Se/Ag composite film exhibits remarkable flexibility, with only 4% loss and 10% loss in electrical conductivity after being bent around a rod of 4 mm radius for 1000 cycles and 2000 cycles, respectively. A seven-leg flexible thermoelectric device assembled with the optimised film demonstrates a voltage of 19 mV and a maximum power output of 3.48 μW (corresponding power density of 35.5 W m−2) at a temperature difference of 30 K. This study provides a potential path to design improved flexible TE devices. Full article
