The application of natural polymers to hydrogel materials with stretchable and compressible properties has attracted more attention. However, made pure are not only poor in mechanical properties, but also lack stability sensitivity strain sensors. Herein, the ionic conductive lignin hydrogels highly (tensile ∼525.1%) (compression ∼95%) performance were formulated by a simple solution blending method. lignin-based ultra-self-adhesive was able adhere various hydrophobic or hydrophilic...
The selective and efficient monitoring of mercury (Hg2+ ) contamination found in the environment ecosystem has been carried out. Thus, a new 1,8-naphthalimide-based fluorescent probe NADP for detection Hg2+ based on fluorescence enhancement strategy designed synthesized. can detect with high selectivity sensitivity low limit 13 nm. mechanism was -triggered deprotection reaction, resulting dramatic change from colorless to green at physiological pH. Most importantly, biological investigation...
Mercury has complex biological toxicity and can cause a variety of physiological diseases even death, so it is great importance to develop novel strategies for detecting trace mercury in environmental samples.
Abstract A highly effective method for the research and development of a novel macroscopic hydrogel sensor bilayer is reported. Based on Rhodamine 6G, an Hg 2+ sensitive fluorescent functional monomer was synthesized, then utilized to synthesize sensors hydrogels. Hydrogel has prominent selectivity , shape changing function additionally. By combining thermoresponsive layer, poly N-isopropylacrylamide (PNIPAM), with selective layer via supramolecular assembly, obtained that can be tailored...

This paper aims at investigating reinforcement effects and mechanisms of four kinds nanoparticles (SiO2, hectorite, Al2O3 TiO2) for double-network hydrogels. Mechanical tests were conducted to determine optimal contents advantages those in improving strength or strechability. The results showed that the hydrogels with a tensile stress 0.33 MPa, compressive 3.38 MPa high fracture energy 1117 J · m−2, while hectorite achieved strain ratio 2280% better elastic modulus 170.2 kPa. discussed terms...
An efficient fluorescent probe Pyr-Rhy based on pyrazole was developed, which can detect Hg2+ in water. Its fluorescence properties were studied by UV-vis and spectroscopy, the study results indicated that this selectively via complexation reaction, then cause a remarkable color change from colorless to pink strong enhancement be observed. Furthermore, showed high sensitivity with detection limit down 2.07 × 10-8 M, its stoichiometric ratio toward ions 1 : 1. The sensing mechanism...
A novel hydrogel with super stability and toughness is obtained by polymerizing acrylamide maleic acid in the presence of poly(vinyl alcohol) chains. Then processed dry‐anneal loading cation solution method order to construct a polymer network containing covalent, crystalline, ionic cross‐links. Various hydrogels are measured via tensile compressive tests determine optimal preparation mechanical properties hydrogels. The show high stress ≈ 8 MPa 25.4 MJ m −3 . exhibits good chemical that...
In this work, a series of porous terpolymers with degrees crosslinking at 30–65% were synthesized by suspension polymerization. Fe 3 O 4 nanoparticles used to modify the terpolymer degree 30%. The resulting mean pore size 10–30 nm as supports for immobilization cellulases through covalent bondings. Fourier transform infrared spectroscopy and thermal gravity analysis measurements demonstrated that immobilized onto terpolymers. effects pH temperature on enzyme activity investigated in acetate...
