However, the existing hydrogels generally have problems of weak tensile capacity, insufficient durability, and being easy to freeze at low temperatures, which greatly affect their application in the field of wearable devices. In this paper, glycerol was partially replaced by water as the solvent, agar was thermally dissolved to initiate acrylamide polymerization, and MXene was used as a conductive filler and initiator promoter to form the double network MXene-PAM\/Agar organic hydrogel. The presence of MXene makes the hydrogel produce more conductive paths and enforces the hydrogel\u2019s higher conductivity (1.02 S\u00b7m\u22121). The mechanical properties of hydrogels were enhanced by the double network structure, and the hydrogel had high stretchability (1300%). In addition, the hydrogel-based wearable strain sensor exhibited good sensitivity over a wide strain range (GF = 2.99, 0\u2013200% strain). The strain sensor based on MXene-PAM\/Agar hydrogel was capable of real-time monitoring of human movement signals such as fingers, wrists, arms, etc. and could maintain good working conditions even in cold environments (\u221226 \u00b0C). Hence, we are of the opinion that delving into this hydrogel holds the potential to broaden the scope of utilizing conductive hydrogels as flexible and wearable strain sensors, especially in chilly environments.<\/jats:p>","DOI":"10.3390\/mi14081563","type":"journal-article","created":{"date-parts":[[2023,8,6]],"date-time":"2023-08-06T10:01:53Z","timestamp":1691316113000},"page":"1563","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":25,"title":["Low-Temperature Adaptive Dual-Network MXene Nanocomposite Hydrogel as Flexible Wearable Strain Sensors"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6645-2032","authenticated-orcid":false,"given":"Kai","family":"Chen","sequence":"first","affiliation":[{"name":"School of Resources and Chemical Engineering, Sanming University, Sanming 365004, China"},{"name":"Fujian Provincial Key Laboratory of Advanced Materials Oriented Chemical Engineering, College of Chemistry and Materials Science, Fujian Normal University, Fuzhou 350007, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenzhong","family":"Lai","sequence":"additional","affiliation":[{"name":"School of Resources and Chemical Engineering, Sanming University, Sanming 365004, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wangchuan","family":"Xiao","sequence":"additional","affiliation":[{"name":"School of Resources and Chemical Engineering, Sanming University, Sanming 365004, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lumin","family":"Li","sequence":"additional","affiliation":[{"name":"School of Resources and Chemical Engineering, Sanming University, Sanming 365004, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shijun","family":"Huang","sequence":"additional","affiliation":[{"name":"School of Resources and Chemical Engineering, Sanming University, Sanming 365004, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiufeng","family":"Xiao","sequence":"additional","affiliation":[{"name":"Fujian Provincial Key Laboratory of Advanced Materials Oriented Chemical Engineering, College of Chemistry and Materials Science, Fujian Normal University, Fuzhou 350007, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,8,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1795","DOI":"10.1039\/D1MH00085C","article-title":"Balancing the Mechanical, Electronic, and Self-Healing Properties in Conductive Self-Healing Hydrogel for Wearable Sensor Applications","volume":"8","author":"Su","year":"2021","journal-title":"Mater.
