By the cyclic dissociation and reassembly of the stimuli-responsive bridges, the reversible switchable transitions of the hydrogels between stiff shaped hydrogel structures and soft shapeless states are demonstrated. 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.

Stimuli responsive shape memory microarchitectures

The controlled stiffness properties of the hydrogel are used to develop shape‐memory hydrogels. In addition, CMC hydrogels crosslinked by donor–acceptor complexes and K + ‐stabilized G‐quadruplexes reveal stimuli‐responsive properties that exhibit dually triggered stiffness functions. Shape memory polymers (SMPs) are materials that can undergo programmable shape change in response to a specific stimulus.

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. In this article, α-keratin hairs were investigated for the combined stimuli of thermo-solvent, solvent-solvent, and UV (radiation)-reductant sensitive SM abilities. The related netpoints and

The related netpoints and Stimuli-responsive shape-memory materials are a category of fascinating smart materials, which undergo reversible shape transformation with environmental changes. Among a large number of stimuli-responsive shape-memory materials, light-driven materials have sparked tremendous attention because of their stability, remote operability and environmentally friendly. Smart polymers (SPs) or stimuli-responsive polymers (SRPs) behave differently to those external stimuli, as their behavior is more rapid and nonlinear in nature and even a small magnitude of external stimulus can cause noticeable changes in their shape, size, color or conductivity.
