Biodegradable cov ntaub ntawv yog cov ntaub ntawv uas tuaj yeem tawg tag rau hauv cov khoom sib xyaw molecular tsawg los ntawm cov kab mob (piv txwv li, kab mob, fungi, thiab algae, thiab lwm yam) nyob rau hauv ib puag ncig ib puag ncig ntawm qhov tsim nyog thiab pom lub sijhawm. Tam sim no, lawv tau muab faib ua plaub pawg tseem ceeb: polylactic acid (PLA), PBS, polylactic acid ester (PHA) thiab polylactic acid ester (PBAT).
PLA muaj biosafety, biodegradability, zoo mechanical zog thiab yooj yim ua, thiab yog dav siv nyob rau hauv ntim, textile, ua liaj ua teb yas zaj duab xis thiab biomedical polymer industries.
PBS tuaj yeem siv rau hauv ntim zaj duab xis, cov tais diav, cov khoom ntim ua npuas dej, lub raj mis siv txhua hnub, lub raj mis tshuaj, cov yeeb yaj kiab ua liaj ua teb, cov tshuaj tua kab tso tawm cov ntaub ntawv qeeb thiab lwm yam haujlwm.
PHA tuaj yeem siv rau hauv cov khoom siv pov tseg, cov ris tsho phais rau cov khoom siv kho mob, ntim thiab ntim cov hnab ntim khoom, cov khoom siv kho mob, kho cov cuab yeej, cov ntaub qhwv, cov koob orthopedic, cov yeeb yaj kiab los tiv thaiv adhesion thiab stents.
PBAT muaj qhov zoo ntawm kev ua yeeb yaj kiab zoo thiab ua kom yooj yim zaj duab xis tshuab, thiab yog siv dav hauv cov khoom ntim khoom pov tseg thiab cov yeeb yaj kiab ua liaj ua teb.
