Ionically-conductive hydrogels are attracting increasing interest as skin-like sensors, however, the fabrication of ion-conductive hydrogels with excellent mech. properties, high conductivity, self-adhesion and anti-freezing ability for high-performance sensors remains a challenge. Herein, a highly ion-conductive hydrogel is prepared by introducing LiCl into polyacrylamide/hydroxypropyl Me cellulose (PAM/HPMC) composite hydrogel. The introduction of LiCl simultaneously endows the PAM/HPMC/LiCl hydrogel with outstanding stretchability (1453 %), high tensile strength (135 kPa), skin-like elasticity (9.18 kPa), high conductivity (7.85 S/m), good adhesiveness and wide operating temperature range. Impressively, this ion-conductive hydrogel can be utilized in skin-like sensor, which achieves high strain sensitivity (GF = 11.19) with wide sensing ranges (up to 600 %), and excellent endurance over 250 consecutive stretching. As a result, the wearable sensor assembled from the hydrogels can be used to detect complex human activities with high stability even at -40 °C. This work promotes the development of ion-conductive hydrogels with broad operating temperature in advanced sensory platform. This study involved multiple reactions and reactants, such as Lithium chloride (cas: 7447-41-8Recommanded Product: Lithium chloride).
Lithium chloride (cas: 7447-41-8) belongs to organic chlorides. Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids. Aliphatic organochlorides are often alkylating agents as chlorine can act as a leaving group, which can result in cellular damage.Recommanded Product: Lithium chloride
