The tunable microarchitectured shape memory triboelectric nanogenerators (mSM-TENG) exhibit self-restoring Stimuli-responsive polymers are the type of polymeric materials defined as the responsive materials with the ability to react, sense, and respond to external condition in a predetermined shape. When stimuli-responsive polymers laminated/coated to a fabric, a smart fabric (waterproof, windproof, and breathable) is formed. A review of stimuli-responsive shape memory polymer composites. Polymer 54 (9), p. 2199–2221 (2013) Tobushhi H., Haray H., Yamaday E. & Hayashi S. Thermomechanical properties in a thin film of shape memory polymer of polyurethane series.

The shape‐memory effect results from the polymer's structure and morphol Is stimuli-responsive good, bad, or exciting? The activation of the shape-memory effect (SME) is what captures the imagination of the engineer or designer. If you are reading this book, you likely have been inspired by the activation in some shape-memory demonstration. A shape-memory alloy is an alloy that can be deformed when cold but returns to its pre-deformed ("remembered") shape when heated. It may also be called memory metal, memory alloy, smart metal, smart alloy, or muscle wire. [citation needed]Parts made of shape-memory alloys can be lightweight, solid-state alternatives to conventional actuators such as hydraulic, pneumatic, and motor-based … Shape memory polymers (SMPs) are materials that can undergo programmable shape change in response to a specific stimulus. The ability to undergo this reliable, three-dimensional shape change makes SMPs promising smart materials for applications like biomedical stents and sutures.

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 The shape-memory effect at the microlevel was quantified by the recovery ratio of cuboids (R r,micro), while at the nanolevel, the recovery ratio of the nanoroughness (R r,nano) was measured. The values of R r,micro could be tailored in a range from 42 ± 1% to 102 ± 1% and R r,nano from 89 ± 6% to 136 ± 21% depending on the applied compression ratio and the amount of vinyl acetate content 2019-12-30 · 4D printing is proposed based on the additive manufacturing of stimuli-responsive materials and structures, which can realize shape changing upon external stimuli.

Also, modeling stimuli-responsive polymers can shed light on agricultural and biological research. An example is demonstrated in the paper titled “Phase Characterization of Cucumber Growth: A Chemical Gel Model.” 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 Like the water responsive shape memory (SM) effect of β-keratin bird feathers, α-keratin hairs either existing broadly in nature are found responsive to many types of coupled stimuli in SM behaviors.
