Self-repairable materials strive to emulate curable and resilient biological tissue; however, their performance is currently insufficient for commercialization purposes because mending toughening are mutually exclusive. Herein, we report a carbonate-type thermoplastic polyurethane elastomer that self-heals at 35 °C exhibits tensile strength of 43 MPa; this as strong the soles used in footwear. Distinctively, it has abundant carbonyl groups soft-segments fully amorphous with negligible phase...
The demand for face masks is increasing exponentially due to the coronavirus pandemic and issues associated with airborne particulate matter (PM). However, both conventional electrostatic- nanosieve-based mask filters are single-use not degradable or recyclable, which creates serious waste problems. In addition, former loses function under humid conditions, while latter operates a significant air-pressure drop suffers from relatively fast pore blockage. Herein, biodegradable,...
Sensors with autonomous self-healing properties offer enhanced durability, reliability, and stability. Although numerous polymers have been attempted, achieving sensors fast reversible recovery under ambient conditions high mechanical toughness remains challenging. Here, a highly sensitive wearable sensor made of robust bio-based supramolecular polymer that is capable via hydrogen bonding presented. The integration carbon fiber thread into matrix provides new toolset can easily be knitted...
Abstract Perishable foods at undesired temperatures can generate foodborne illnesses that present significant societal costs. To certify refrigeration succession in a food‐supply chain, flexible, easy‐to‐interpret, damage‐tolerant, and sensitive time‐temperature indicator (TTI) uses self‐healing nanofiber mat is devised. This opaque when refrigerated due to nanofiber‐induced light scattering, but becomes irreversibly transparent room temperature through self‐healing‐induced interfibrillar...
Abstract With the development of wearable electronics, use engineered functional inks with printing technologies has attracted attention owing to its potential for applications in low‐cost, high‐throughput, and high‐performance devices. However, improvement conductivity stretchability mass production is still a challenge practical applications. Herein, scalable efficient fluid dynamics process that produces highly stretchable, conductive, printable containing high concentration graphene...
Stretchable sensors based on conductive hydrogels have attracted considerable attention for wearable electronics. However, their practical applications been limited by the low sensitivity, high hysteresis, and long response times of hydrogels. In this study, we developed high-performance poly(vinyl alcohol) (PVA)/poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) post-treated with NaCl, which showed excellent mechanical properties, fast electrical response, ultralow...
A new molecular dynamics for transparent and self-healing elastomers are developed that uses aliphatic disulfide H-bond acceptors to produce colorless waterproof coatings, particularly in display applications.
Sustainable, transparent, and robust bio-polycarbonate nanocomposites are realized by<italic>in situ</italic>polymerization of isosorbide well-dispersed with cellulose nanocrystals.
Superior elastic recovery and rapid enzymatic degradation rate were realized by utilizing 2,5-furan dicarboxylic acid as a sustainable substitute for terephthalate.
In order to achieve high-quality 3D printing of inorganic materials, a thorough evaluation appropriate rheological characteristics and methodologies for formulating all-inorganic inks is required. We recently reported using BiSbTe-based thermoelectric particles coupled with chalcogenidometallate (ChaM) binder. the current study, we analyzed behavior assess printability structural retention respect ChaM content. The stress sweep three-interval thixotropy test (3ITT) were conducted mimic...
Poly(vinylidene fluoride) (PVDF)/graphene oxide (GO) nanocomposite fibers were dry-jet wet spun at the GO concentrations of 0, 1, and 2 wt % with respect to polymer. The as-spun drawn in draw ratio (DR) range 2–6.5, correlation between PVDF chain conformation mechanical properties upon drawing has been studied by two-dimensional spectroscopy Fourier-transformed infrared, wide-angle X-ray diffraction, differential scanning calorimetry, tensile testing. PVDF/GO exhibited that mobile crystals...

Biodegradable aliphatic polyesters need to be tough for commodity-plastic applications, such as disposable bags. Herein, we show that chitosan nanowhiskers (CsWs) prepared from naturally abundant chitin is an effective nanofiller reinforces the strength and toughness of poly(butylene succinate) (PBS). In-situ polycondensation aqueous solution processed CsWs led a PBS nanocomposite with highest tensile (77 MPa) elongation at break (530%) reported date all types minimal content 0.2 wt%. The...
Immunotherapies have been gaining attention for the prevention of cancer recurrence and metastasis. Cancer immunotherapy can induce memory cells to target cancer-specific antigens and, thus, selectively kill cells. However, there are difficulties in inducing antigen-specific immunity due limited knowledge regarding antigens. In this study, we synthesized a dual-functional hydrogel antigen generation immune activation.To elicit self-antigen-specific response, an alginate-collagen-based...
