Cov khoom siv tseem ceeb ntawm cov khoom siv hluav taws xob yog cov organic polymer nrog lub conjugated π-electron system. Cov qauv conjugated no tso cai rau cov hluav taws xob txav mus rau delocalized raws cov saw molecular, yog li muab cov khoom siv nrog cov conductivity. Cov khoom siv hluav taws xob ntau tshaj plaws suav nrog polyaniline (PANI), polypyrrole (PPy), thiab polythiophene thiab nws cov derivatives (xws li PEDOT: PSS). Cov polymers tsim cov saw hlau ruaj khov los ntawm kev siv tshuaj lom neeg los yog kev kho doping. Qhov sib txawv ntawm cov qauv molecular ntawm cov polymers sib txawv cuam tshuam rau lawv cov conductivity, thermal stability, thiab kev ua kom haum.
Nyob rau hauv cov nqe lus ntawm cov khoom siv, conductive polymers muaj ob qho tib si saj zawg zog thiab processability thaum tuav zoo conductivity. Piv txwv li, polypyrrole tuaj yeem ua tiav rau hauv cov yeeb yaj kiab thiab fibers los ntawm kev daws txheej lossis luam ntawv, polyaniline nthuav tawm cov tshuaj lom neeg ruaj khov thiab kev tiv thaiv corrosion, thiab polythiophene thiab nws cov derivatives ua ke transparency thiab tunable conductivity. Cov yam ntxwv no ua rau cov khoom siv hluav taws xob tau siv dav hauv cov khoom siv hluav taws xob hloov pauv, kov cov ntxaij vab tshaus, cov khoom siv hluav taws xob, thiab cov txheej txheem tiv thaiv zoo li qub, tsis txwv los ntawm cov duab thiab nruj ntawm cov khoom siv hlau.
Conductive polymer cov ntaub ntawv muab kev hloov pauv tshuaj lom neeg thiab kev ua haujlwm sib xyaw ua haujlwm. Los ntawm kev qhia cov pab pawg ua haujlwm sib txawv, copolymerizing, lossis sib txuas nrog cov khoom siv nano, kev coj ua, thermal stability, thiab cov khoom siv kho tshuab tuaj yeem kho. Piv txwv li, PEDOT: PSS, vim nws cov dej solubility zoo, tuaj yeem yooj yim ua ke nrog lwm cov polymers lossis substrates los tsim cov yeeb yaj kiab pob tshab, thaum polyaniline nthuav tawm cov kev ua tau zoo dua tom qab cov kua qaub doping. Cov ntaub ntawv yooj yim no tso cai rau cov khoom siv hluav taws xob tsis yog tsuas yog ua tau raws li qhov yuav tsum tau ua ntawm cov khoom siv hluav taws xob nkaus xwb tab sis kuj ua tiav kev sib koom ua ke, muab cov khoom siv rau cov sensors, cov khoom siv hluav taws xob, thiab cov khoom ntse.
