E le thepa ea mahlakore a mararo e nang le metsi a mangata, hydrogel e na le litšobotsi tsa elasticity e phahameng, pepeneneng le biocompatibility. E 'nile ea sebelisoa haholo ho lilense tsa ho kopana, litlolo, boenjiniere ba lisele, ho roala maqeba le likarolo tse ling. Lilemong tsa morao tjena, li-hydrogel tsa conductive li 'nile tsa sebelisoa haholo tšimong ea li-sensor le lisebelisoa tsa elektroniki tse tenyetsehang. Leha ho le joalo, li-hydrogel tse tloaelehileng li lahleheloa ke thepa ea tsona ea pele ka lebaka la serame ka mocheso o tlase, li fokotsa ts'ebeliso ea tsona ka mocheso o tlase.

Wang Yang, lv ang le zhang lina, bao e leng liprofesa tse amanang le univesithi ea Wuhan, ba atlehile ho lokisa antifreeze ionic conductive cellulose hydrogel, e ka sebelisoang e le tsitsipano, khatello le sensor ea mocheso. Ho fapana le li-hydrogel tsa setso, thepa ea tsona ea antifreeze e li lumella ho sebetsa hantle mochesong o tlase ho zero. Liphuputso li hatisitsoe koranteng ea ACS Applied Materials & Interfaces.

Senotlolo sa antifreeze le conductivity ea motlakase ea cellulose hydrogels se lutse ka benzyl trimethyl ammonium hydroxide, tharollo e nang le metsi a organic base e leng e 'ngoe ea lisebelisoa tse ncha tsa cellulosic tse entsoeng ke sehlopha, thuto e boletse. Ka mor'a ho kopanya lik'hemik'hale tsa tharollo ea selulose, setsi sa organic e le solvent ha se hlatsuoe joalo ka mokhoa oa setso oa ho lokisa, empa se bolokiloe ka ho toba. Thepa ea eona e le electrolyte e fa cellulose hydrogel thepa ea antifreeze le conductive ka kakaretso.

Ts'ebetso ea li-hydrogel tsa setso tsa cellulose le antifreeze cellulose hydrogel ka mocheso o tlase

Bafuputsi ba - 24 ℃ mocheso o tlase o tla emisa ho hanyetsa conductive hydrogel e tsitsitseng manonyeletsong a menoana, ebang ke ka lehlakoreng le le leng le le leng le le leng le le leng le le leng le potlakileng kapa le liehang ka nako e fapaneng, ho hanyetsa ha gel ea conductive ea metsi ho ka fetoha ka ho sisinyeha ha menoana ho bontša boholo ba phetoho e lumellanang le lerata le sa bonahaleng kapa hysteresis, deformation ea metsi ka lebaka la ho se be teng ha metsi. thepa e tsitsitseng ea mochine ka mocheso o tlaase oa mocheso - ho hanyetsa le ts'ebetso e utloahalang ea karabo.
