Special Issue Information

Dear Colleagues,

The need for sustainability in Materials Science and Technology is in the focus of this Issue, with particular emphasis on the need for multifunctional applications of polymer composites, biopolymers, capacitors, and hydrogels.

(1) Natural abundant polymers, such as cellulose, are currently being tested for their suitability as sustainable wearable technology in energy storage, sensors, and actuators. Various composites can fulfill the need for renewable, sustainable materials. Conducting polymers are often applied in these composites to find materials and technologies that can provide the sustainability needed for future smart applications. Hydrogels are presently being tested as wearable strain sensors with dual or multifunctional applications. The biotechnology of sustainable functions, primarily referred to as biosensors, must also be sustainable. The future of materials science is envisaged as being integrated with sustainable management without the loss of their applications as smart materials. Ground research in understanding the mechanism of smart materials is also welcome.

(2) The aim of this Special Issue is to demonstrate materials and technology that show sustainability and may be used as advanced materials applicable in green technology.    

(3) Sensors and actuators of materials functionality;

Energy storage of sustainable materials;

Sustainability of polymer composites;

Green Technology of Materials that maintain their multi-functionality.

In this Special Issue, original research articles and reviews are welcome.

I look forward to receiving your contributions.

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. Sustainability is an international peer-reviewed open access semimonthly journal published by MDPI.

Nowadays, the research community envisions smart materials composed of biodegradable, biocompatible, and sustainable natural polymers, such as cellulose. Most applications of cellulose electroactive materials are developed for energy storage and sensors, while only a few are reported for linear actuators. Therefore, we introduce here cellulose-multiwall carbon nanotube composite (Cell-CNT) fibers compared with pristine multiwall carbon nanotube (CNT) fibers made by dielectrophoresis (DEP) in their linear actuation in an organic electrolyte. Electrochemical measurements (cyclic voltammetry, square wave potential steps, and chronopotentiometry) were performed with electromechanical deformation (EMD) measurements. The linear actuation of Cell-CNT outperformed the main actuation at discharging, having 7.9 kPa stress and 0.062% strain, making this composite more sustainable in smart materials, textiles, or robotics. The CNT fiber depends on scan rates switching from mixed actuation to main expansion at negative charging. The CNT fiber-specific capacitance was much enhanced with 278 F g−1, and had a capacity retention of 96% after 5000 cycles, making this fiber more sustainable in energy storage than the Cell-CNT fiber. The fiber samples were characterized by scanning electron microscopy (SEM), BET (Braunauer-Emmett-Teller) measurement, energy dispersive X-ray (EDX) spectroscopy, FTIR, and Raman spectroscopy.
