The occurrence of martensite-to-austenite and austenite-to- The shape of the fibers in each process, including the temporary shape for investigating the fixation ability and recovered shape for memory ability, were observed using a camera; (3) the effect of the coupled stimuli factor on the shape recovery of the fibers was observed: ①/②/③ the temporary spiral hairs encountered with water/water/reductant solution (NaHSO 3, 1 mol/L) and the shape The researchers provide an overview in their paper of how some of the latest stimuli-responsive biomaterials (SRBs), which include the shape memory polymer, are used to mimic the dynamic A shape-memory adhesive has been prepared that exhibits two levels of reversible adhesion. The adhesive is a semicrystalline cross-linked polymer that contains dynamic disulfide bonds. Melting of the crystalline regions via heat causes a drop in the modulus of the material facilitating wetting of the substrate as well as enhancing the surface contact area with the substrate, which result in Abstract. Multistimuli‐responsive shape‐memory polymers are highly desirable in various applications, and numerous modes have been developed in recent years. However, most of them need to reprogram before they are ready to respond to another stimulus while one is triggered.

In this work, we reported a multi-responsive luminescent hydrogel with properties of encryption, naked eye sensing of glucose, shape memory, self-healing, and antibacterial activity. The hydrogel (GA/CCS/DNSA/Eu3+) was obtained by mixing phenylboronic acid-modified gelatin (GA-DBA), catechol-modified carboxymethyl chitosan (CCS-PCA), 3,5-dinitrosalicylic acid (DNSA), and Eu3+ ions through a

2018-05-22 Smart polymers, stimuli-responsive polymers or functional polymers are high-performance polymers that change according to the environment they are in. Such materials can be sensitive to a number of factors, such as temperature, humidity, pH, chemical compounds, the wavelength or intensity of light or an electrical or magnetic field and can respond in various ways, like altering colour or Polymer particles that switch shape in response to a stimulus Jin-Wook Yoo and Samir Mitragotri1 Department of Chemical Engineering, University of California, Santa Barbara, CA 93106 Edited* by David A.
