Abstract Conductive, flexible and stretchable hydrogel sensors have attracted a lot of interest in human-machine interfaces, medical monitoring, and soft robotics. However, there are still have great challenges in the preparation of conductive hydrogels with self-adhesive, self-power and antibacterial properties. In order to meet the requirements of high sensitivity, convenient carrying and anti-allergic, so as to overcome the problems of traditional sensors, such as non-stickiness, absolute dep...

Abstract null null Reduction and temperature dually responsive poly(2-(2-methoxyethoxy)ethylmethacrylate-co-oligo(ethylene glycol) methacrylate)-b-poly(e-caprolactone)-SS-poly(e-caprolactone)-b-poly(2-(2-methoxyethoxy)ethylmethacrylat-co-oligo(ethylene glycol) methacrylate) (P(MEO2MA-co-OEGMA)-b-PCL-SS-PCL-b-P(MEO2MA-co-OEGMA)) was synthesized by the combination of ring-opening polymerization (ROP) and atom transfer radical polymerization (ATRP). The copolymer can self-assemble into spherical mi...

Flexible and intelligent electronics are highly demanded in wearable devices and systems, but it is still challenging to fabricate conductive textiles with good stretchability, multifunctionality, and responsiveness to multistimuli. Therefore, kinds of smart conductive fabrics with high stretchability and thermal properties, good washability, excellent shape stability, rapid responsiveness to external stimuli (e.g., electrical and photonic), and outstanding energy conversion and storage properti...

As a flexible wearable device, hydrogel-based sensors have attracted widespread attention in soft electronics. However, the application of traditional hydrogels at extreme temperatures or for a long-term stability still remain a challenge because of the existence of water. Herein, we reported an antifreezing and antidrying organohydrogel with high transparency (over 85% transmittance), high stretchability (up to 1200%), and robust adhesiveness to various substrates, which consist of polyacrylic ...

Abstract Compared to conventional chemotherapy with subcutaneous and intravenous injection, injection of self-healing hydrogel drug-delivery system to tumor site brings less toxicity for normal tissues, but also better specificity for tumor cells on account of spontaneous repair and better retention. More importantly, it is essential to introduce multifunctional nanomaterials into self-healing hydrogel loading chemotherapeutic drugs to significantly enhance tumor treatment effect. Therefore, Rho...

Amphiphilic random copolymers poly(isopropylacryamide-co-acrylic acid-co-2-nitroimidazole acrylate) (P(NIPAM-co-AA-co-NIA)) with different contents of 2-nitroimidazole (NI) group were facilely synthesized through RAFT and EDC reactions. These random copolymers self-assembled into spherical micelles at room temperature through dialysis method. NI groups exhibited stimulus responsiveness under hypoxia condition. The hydrophobicity-hydrophilicity transformation could be realized through the change ...

Injectable and self-healing hydrogels with thermoresponsiveness as the smart hydrogel could achieve the injectability and heal automatically, and the phase and volume changes as well. Here, the thermoresponsive self-healing hydrogel was prepared via the dynamic covalent enamine bonds between the amino groups in polyetherimide (PEI) and the acetoacetate groups in four-armed star-shaped poly(2-(dimethylamino)ethyl methacrylate-co-2-hydroxyethyl methacrylate) modified with tertiary-butyl acetoaceta...

A dumbbell-shaped copolymer (PDMAEMA)4-PCL-SS-PCL-(PDMAEMA)4 with a lower critical solution temperature (LCST) and redox responses was first synthesized by the combination of ring opening polymerization (ROP), click chemistry and atom transfer radical polymerization (ATRP). Then a dumbbell-shaped copolymer (PDMAPS)4-PCL-SS-PCL-(PDMAPS)4 with an upper critical solution temperature (UCST) and redox responses was obtained through the quaternization reaction between DMAEMA and excess 1,3-propane sul...
