Conductive hydrogels yog cov khoom siv hydrogel nrog cov khoom siv hluav taws xob, dav siv hauv biomedicine, lub zog cia, sensors, thiab lwm yam. Raws li lawv muaj pes tsawg leeg, kev npaj, thiab daim ntawv thov thaj chaw, conductive hydrogels tuaj yeem muab faib ua ntau hom sib txawv. Kab lus no yuav muab cov ncauj lus qhia ntxaws ntxaws rau kev faib tawm ntawm cov hluav taws xob hydrogels thiab sib tham txog lawv cov yam ntxwv thiab kev siv.
Raws li cov khoom sib txawv, cov khoom siv hluav taws xob tuaj yeem muab faib ua cov organic conductive hydrogels thiab inorganic conductive hydrogels.
1. Organic Conductive Hydrogels
Organic conductive hydrogels yog tsim los ntawm cov khoom siv organic uas muaj cov qauv sib txuas heev. Cov ntaub ntawv no muaj qhov yooj yooj yim thiab stretchability, tswj kev ruaj ntseg zoo thaum lub sij hawm ncab. Cov ntaub ntawv organic feem ntau suav nrog cov polymers thiab carbon nanotubes.
Polymers yog ib qho ntawm cov khoom siv feem ntau los npaj cov organic conductive hydrogels. Polymers tuaj yeem tsim ib qho peb -cov qauv sib txuas sib txuas los ntawm cov tshuaj lom neeg lossis lub cev sib txuas- txuas, embedding ions lossis ionic pawg hauv nws kom ua tiav lawv cov khoom siv hluav taws xob. Cov polymers muaj xws li polyacrylic acid thiab polyvinyl cawv.
Cov pa roj carbon nanotubes yog cov khoom siv nano uas muaj cov khoom siv zoo heev thiab feem ntau siv rau hauv kev npaj cov organic conductive hydrogels. Cov pa roj carbon nanotubes tuaj yeem ua ke nrog cov polymers los ntawm kev hloov kho tshuaj lossis kev sib xyaw ntawm lub cev los tsim cov khoom siv hydrogel nrog cov khoom siv hluav taws xob.
2. Inorganic Conductive Hydrogels
Inorganic conductive hydrogels yog tsim los ntawm inorganic cov ntaub ntawv uas muaj hlau los yog hlau oxides. Cov ntaub ntawv no muaj cov khoom siv hluav taws xob zoo thiab tshuaj lom neeg ruaj khov thiab feem ntau yog siv los npaj siab -cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob.
Hlau oxides yog ib chav kawm ntawm cov khoom siv hauv inorganic conductive hydrogels. Piv txwv li, zinc oxide, tooj liab oxide, thiab lwm yam hlau oxides tuaj yeem npaj rau hauv hydrogels nrog cov hluav taws xob zoo los ntawm cov txheej txheem solvothermal, cov txheej txheem hnyav combustion, thiab lwm yam.
Tsis tas li ntawd, hlau nanoparticles kuj tau siv dav hauv inorganic conductive hydrogels. Hlau nanoparticles tuaj yeem ua ke nrog polymers lossis lwm yam matrices los ntawm kev txo cov kuab tshuaj, txoj kev photoreduction, thiab lwm yam, los tsim cov khoom siv hydrogel ruaj khov thiab tswj tau.
