Abstract An effective approach to develop a novel macroscopic anisotropic bilayer hydrogel actuator with on–off switchable fluorescent color‐changing function is reported. Through combining collapsed thermoresponsive graphene oxide‐poly( N ‐isopropylacrylamide) (GO‐PNIPAM) layer pH‐responsive perylene bisimide‐functionalized hyperbranched polyethylenimine (PBI‐HPEI) via supramolecular assembly, obtained that can be tailored and reswells form 3D actuator. The undergo complex shape deformation...
A general strategy for fabricating a double layer self-deformed shape memory hydrogel which includes thermo-responsive actuating and pH-responsive memorizing is presented. Compared with traditional polymer systems, the temporary of could be generated by upon trigger heat without need an external force, further memorized layer.
Poor, nontunable mechanical properties as well finite shape memory performance pose a barrier to hydrogels realize practical applications. Here, new hydrogel with tunable and multishape effect was presented. Three programmable reversible systems including PBA-diol ester bonds, AAc-Fe3+, coil-helix transition of agar were applied memorize temporary shapes endow the outstanding functionalities. Moreover, through changing cross-linking densities, as-prepared can be adjusted.
Abstract Although shape memory polymers have been highlighted widely and developed rapidly, it is still a challenging task to realize complex temporary shapes automatically in practical applications. Herein, novel hydrogel with the ability of self‐deformation presented. Through constructing an anisotropic poly(acrylic acid)–polyacrylamide (PAAc–PAAm) structure, obtained exhibits stable behavior response pH stimulus, that formed can be fixed by coordination between carboxylic groups Fe 3+ ;...
Abstract The effect of structural parameters such as hard segment content and cross‐linking degree on the mechanical properties waterborne self‐healing polyurethane tensile strength, conditions (temperature, time) were investigated. These results demonstrated that increasing segments/the agent, strength sample increased performance exhibited a downward trend. When reached 40 MPa, it could hardly healed, even if prolonging time or temperature. Mechanism study ability was attributed to dynamic...
A novel multiple shape memory hydrogel is fabricated based on two reversible physical interactions. The property endowed by a simple treatment of soaking in NaOH or NaCl solutions to form chitosan microcrystal chain-entanglement crosslinks as temporary junctions.
Abstract Realization of shape memory process in polymeric hydrogels at ambient condition is a significant development to materials. The sound understanding the dynamic fundamentally important but limited. Here, novel hydrogel with simultaneously switchable fluorescence behavior developed. prepared by incorporating pH‐responsive fluorescent molecule, perylene tetracarboxylic acid, into chitosan‐based hydrogel, and assembly disassembly chitosan chains microcrystals upon trigger pH are applied...
Abstract Bio‐based polyols derived from vegetable oils generally contain the dangling chains, which have recently attracted significant attention due to their influence on preparation and performance of waterborne polyurethane. Herein, a novel undecylenic‐based primary glycol (UPG) without chains synthesized oleic‐based (OPG) with reported by our previous work were used prepare straight‐chain dangling‐chain bio‐based polyurethane (BWPU), respectively, study difference between two diols...
ABSTRACT Crosslinked castor oil (CO)‐based waterborne polyurethane was synthesized from CO, polycarbonate diol, isophorone diisocyanate, 2,2‐dimethylol propionic acid, and 2‐amino‐2‐(hydroxymethyl)‐1,3‐propanediol (THAM) using pre‐polymer process. Fourier transform infrared spectroscopy, X‐ray diffraction, transmission electron microscopy were utilized to characterize the above‐synthesized polyurethane. The effect of THAM content studied on particle size, zeta potential, thermogravimetric...
Abstract Hyperbranched polyesters (HPs) with a variable content of benzoyl terminal groups were synthesized through the chemical modification HPs' cores by substituting controlled fraction hydroxyl chloride. The resulting hyperbranched polymers that modified (HPs‐B) characterized 1 H NMR, FTIR, differential scanning calorimetry (DSC), and gel permeation chromatography (GPC). Research results revealed self‐assembled structures could be formed in selected solvents (acetone/ n ‐hexane). It was...
