Multifunctional polyurethane elastomers with high mechanical robustness and exceptional crack tolerance performance based on bi-incompatible soft segments and dynamic coordination bonds
Elastomers with high strength and super toughness are widely used in aerospace, flexible electronics, biomedical, and other fields.
Polysiloxane-based polyurethane/quaternary ammonium-zwitterionic pressure-sensitive adhesive composite double dressing with antimicrobial and antifouling properties
Soft & robust protective layer based on controllable aggregation of polyurethane; combination of antimicrobial and antifouling based on cationic and zwitterionic ions; excellent adhesion and water vapor transmission rate for promoting wound healing.
Electron-ion coupling enables ionic hydrogel with high thermopower for low-grade heat harvest and sensitive fire warning
We developed triple-network ionic hydrogel APSG via electron-ion synergy. High strength (1.49 MPa), 4.25 mV/K Seebeck coefficient, outputs 2.5 V (ΔT = 20 K), exceptional flame retardancy (LOI = 42.3%) & 1.7 s fire warning response.
Percolation-enabled long-range ion transport to achieve conductivity leap in PVDF-based electrolytes
A two-order-of-magnitude conductivity leap emerges in PVDF electrolytes at a critical solvent content of ∼7 wt%. This leap is driven by a shift from local ion hopping to long-range, continuous transport via a percolation network.
Light-activated antimicrobial polymers with citronellol-enhanced bacterial accumulation for on-demand disinfection
Synergistic photobactericidal polymers that integrate hydrophilic toluidine blue O with lipophilic citronellol exhibit significantly improved photodynamic antimicrobial activity against a variety of pathogens, including multidrug-resistant bacteria.
A water-soluble NIR-II fluorescent probe for non-invasive real-time detection of blood ATP via optoacoustic and fluorescence imaging
The water-soluble probe HCD9–Zn[II] has been developed, which is ATP-responsive, enabling real-time and non-invasive monitoring of blood ATP levels via optoacoustic and NIR-II fluorescence imaging.
High-thermopower ionic thermoelectric hydrogels for low-grade heat harvesting and intelligent fire protection
An ionic thermoelectric hydrogel (HIG) for heat harvesting and fire protection was prepared. NaCl modulation enabled p–n conversion and p–n junction exhibited a much higher thermopower. HIG showed good potential for applications in supercapacitors.
