Special Issue Information

Dear Colleagues,

It is a very common phenomenon in Nature that organisms respond to changes in the environment. For example, Mimosa leaves close immediately when they are touched by external forces, chameleons change their colors according to the external environment, and cuttlefish escape by “inkjet” when they encounter strong enemies.

Shape-memory polymers and their composites are a kind of intelligent material that can switch between a temporary shape and the initial shape under corresponding external stimuli. Due to their light weight, large deformation, controllable performance and other advantages, the related basic frontier research and potential application developments have always been the focus of researchers.

In recent decades, shape-memory polymers have stimulated extensive and in-depth research and show great application prospects in the fields of medical devices, aerospace, transportation, intelligent devices, etc.

This Special Issue will publish high-quality original research papers in the overlapping fields of:

  • Synthesizing and curing kinetics of SMPs and SMPCs;
  • Multifunctional SMPs and nanocomposites;
  • Multi-stimuli-triggered SMPs and SMPCs;
  • Remotely and sequentially controlled SMPs and SMPCs;
  • Self-healing SMPs and SMPCs;
  • Four-dimensional printing of SMPs and SMPCs;
  • Biomedical applications;
  • Aerospace and space applications;
  • Civil infrastructure applications;
  • Textile applications.

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. Applied Sciences 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 2400 CHF (Swiss Francs).

In this work, a NiTi shape memory alloy (SMA) wire was embedded into a rubber/shape memory polymer (SMP) soft matrix to form a composite strip with a two-way reversible bending behavior. First, the elastic moduli of SMA wire were characterized as increasing about 3 times (18.6 GPa at martensite phase and 50.1 GPa at austenite phase) from 25 °C to 90 °C. Then, an SMA composite strip using SMP to replace the rubber matrix was fabricated to significantly improve the load-bearing ability (16-fold) at 28 °C. After that, the good two-way bending behaviors of the rubber/SMP-based SMA strip with high shape deploying ratio above 80% were demonstrated. Finally, the application of rubber/SMP-based composite strips in a space-deployable antenna model with two-way reversible bending behavior was developed and demonstrated through a heating and cooling temperature cycle.
