“…For example, by combining AAm or AAc with NIPAM, diethylacrylamide or vinylacetamide, hydrogels showing both LCST and UCST responsiveness can be formed. Other examples of hydrogels showing dual thermoresponsivity are copolymers of poly(ethylene glycol) and poly(acrylamide‐ co ‐acrylonitrile), and poly(imidazoled glycidyl methacrylate‐ co ‐diethyleneglycol methyl ether methacrylate) . Also, researchers have directed efforts at enhancing the biocompatibility and biodegradability of thermoresponsive hydrogels .…”

Hydrogels, which are hydrophilic soft porous networks, are an important class of materials of broad relevance to bioanalytical chemistry, soft‐robotics, drug delivery, and regenerative medicine. Transformer hydrogels are micro‐ and mesostructured hydrogels that display a dramatic transformation of shape, form, or dimension with associated changes in function, due to engineered local variations such as in swelling or stiffness, in response to external controls or environmental stimuli. This review describes principles that can be utilized to fabricate transformer hydrogels such as by layering, patterning, or generating anisotropy, and gradients. Transformer hydrogels are classified based on their responsivity to different stimuli such as temperature, electromagnetic fields, chemicals, and biomolecules. A survey of the current research progress suggests applications of transformer hydrogels in biomimetics, soft robotics, microfluidics, tissue engineering, drug delivery, surgery, and biomedical engineering.

“…In a typical procedure, 15.0163 g of PTFEMA- b -P(iGMA- co -MEO 2 MA) and 50.1235 g of imidazole were dissolved in 500 mL of DMF. This mixture was stirred in an oil bath at 65 °C for 12 h. The final product was purified via the method described in the previous report . The purified PTFEMA- b -P(iGMA- co -MEO 2 MA) was dried under vacuum at 25 °C to generate 17.5301 g of the product in a 97.9% yield.…”

“…LCST and UCST, respectively, correspond to the critical temperature points below and above which a polymer solution becomes opaque. , The LCST polymers are easily prepared, and there have been some reports about modified membranes based on LCST polymers. , However, LCST polymer-modified membranes have some drawbacks that limit their practical applications. The common LCST polymers are soluble in water at room temperature, with typical examples including poly( N -isopropylacrylamide) (PNIPAAM) and poly((2-dimethylamino)ethyl methacrylate) (PDMAEMA), which have LCSTs of 32 and 37 °C, respectively. , These polymers become stretched when the modified membranes based on them are operated at room temperature. However, increasing the temperature up to or above the LCST causes these polymers to contract, while the integrated foulant will remain in place.…”

Poly(2,2,2-trifluoroethyl methacrylate)-b-poly(imidazoled glycidyl methacrylate-co-diethylene glycol methyl ether methacrylate) (PTFEMA-b-P(iGMA-co-MEO2MA)) containing an upper critical solution temperature (UCST) polymer chain was prepared and blended with poly(vinylidene fluoride) (PVDF) to produce a thermoresponsive membrane with smart self-cleaning performance. The successful preparation of the membrane was demonstrated by attenuated total reflection–Fourier-transform infrared spectroscopy, X-ray photoelectron spectroscopy, and scanning electron microscopy characterization. The membrane shows UCST performance, and its flux changes with the filtrate temperature as the UCST polymer chain stretches out and contracts in response to various temperatures. In addition, the UCST polymer chain can disrupt the foulant and push it away from the membrane when the temperature is above the UCST and thus enables membranes to exhibit a smart self-cleaning behavior. To the best of our knowledge, this work is the first report of a smart self-cleaning membrane based on the blending of a diblock copolymer containing a UCST polymer chain with PVDF.
