“…Environmental stimulus‐responsive hydrogels are a class of polymers whose solubility, volume, shape, and configuration can change reversibly in response to external physical or chemical stimuli. [ 1–46 ] External stimuli normally alter ionic interaction, hydrogen bonding, or hydrophobic forces of the polymer systems, leading to invertible microphase separation or self‐assembly. Such smart, sensitive, and multifunctional materials have been applied in drug release, biomedical materials, protein purification, therapeutic agents, industrial coatings, sensors, optical devices, and emulsion stabilization.…”

“…Among all environmentally sensitive hydrogels, temperature‐responsive hydrogels, such as poly( N ‐isopropylacrylamide) (PNIPAM) and its related hybrid copolymers, have received the most attention due to their smart tunable properties. [ 1–44 ] PNIPAM hydrogel polymer chains of low critical solution temperature (LCST, usually around 32 °C) stretch with hydrophilicity at low temperature (below LCST) and shrink with hydrophobicity at high temperature (above LCST). The reason is that in PNIPAM hydrogels, the side group NHCO is hydrophilic, but the main chain is hydrophobic.…”

As a kind of temperature‐responsive hydrogel, polystyrene‐co‐poly(N‐isopropylacrylamide)/poly(N‐isopropylacrylamide) (PS‐co‐PNIPAM/PNIPAM) core–shell nanoparticles prepared by two‐step copolymerization are widely studied and used because of their specific structures and properties. Unlike most reports about the steady stability of PS‐co‐PNIPAM/PNIPAM core–shell nanoparticle hydrogel emulsion, in this work, the PS‐co‐PNIPAM/PNIPAM core–shell nanoparticle hydrogel emulsion (symbolized as PS/PNIPAM hydrogel emulsion), which is prepared after the second step of synthesis and without washing out a large number of PNIPAM polymer segments, shows a reversible temperature‐dependent sol–gel transition characteristic during the temperature range of 34–80 °C. The PS/PNIPAM hydrogel emulsion is a normal solution at room temperature, and it changes from a sol to a gel statue when the temperature approaches up to low critical solution temperature (LCST). As the temperature continues to increase, the gel (core–shell nanoparticles as the crosslinkers and the linear PNIPAM chain as the 3D gel network) of the PS/PNIPAM hydrogel emulsion gradually shrinks and drains linearly. Compared with most crosslinked hydrogels, the hydrogel here can be arbitrarily changed in shape according to use needs, which is convenient for use, transportation, and storage. Here a new route is provided for the preparation of a PS/PNIPAM core–shell hydrogel nanoparticle system, as well as a new supramolecular crosslinking sol–gel system for application in biomedical materials, sensors, biological separation, drug release, macromolecular adsorption, and purification.

Electrically conductive, yet stimuli-responsive hydrogels are highly desirable for many technological applications. However, the discontinuous conductivity of hydrogels during the response process has become a bottleneck that limits their application. To overcome this constraint, a linearly tunable, electrically conductive hydrogel is prepared using in-situ polymerized polyaniline (PANI) on a CNFs/MEO MA/PEGMA hydrogel (PANI@CMP hydrogel) substrate. The PANI@CMP hydrogel exhibits temperature-tunable electrical conductivity due to the liner relationship between thermosensitivity and temperature of the CMP hydrogel substrate. Furthermore, the stiffness and elasticity of the resultant hydrogel after PANI introduction is enhanced via physical interactions, and the compression load is improved by 42%. A highly sensitive temperature sensor is therefore fabricated with PANI@CMP hydrogel as the flexible induction element, and this sensor achieves temperature monitoring from 20 to 60 °C. This new temperature-controllable conductive hydrogel has excellent mechanical properties, showing great potential for applications in flexible smart sensors, conductive fillers, and medical devices.

A series of pH-temperature dual stimuli-responsive random copolymers poly[N,N-dimethylaminoethyl methacrylate-co-poly(poly(ethylene glycol) methyl ether methacrylate][poly(DMAEMA-co-MPEGMA)] were synthesized by free radical polymerization. The supramolecular hydrogel was formed by pseudopolyrotaxane, which was prepared with the host-guest interactions between a-cyclodextrin (a-CD) and poly(ethylene glycol) (PEG) side chains. Fourier transform infrared (FT-IR), nuclear magnetic resonance ( 1 H NMR), and X-ray diffraction (XRD) confirmed the structures of the hydrogels. The pH-temperature dual stimuli responsive properties of the hydrogels were characterized by rheometer. Finally, the controllable drug release behavior of the hydrogel, which was used 5-fluorouracil (5-Fu) as the model drug, was investigated at different temperatures and different pH values.
