Ntim khoom nojyog ib qho kev ntsuas tseem ceeb los xyuas kom meej tias kev thauj mus los, kev muag khoom thiab kev siv cov khoom lag luam tsis raug kev puas tsuaj los ntawm ib puag ncig sab nraud thiab txhim kho tus nqi ntawm cov khoom muag.Nrog rau kev txhim kho txuas ntxiv ntawm cov neeg nyob hauv lub neej zoo, qhov cuam tshuam ntawm cov khoom ntawm cov neeg nyob hauv lub neej niaj hnub tau nce zuj zus, thiab qhov teeb meem ntawm cov pa phem dawb tau dhau los ua qhov hnyav dua.Biodegradable polymer cov ntaub ntawv tau dhau los ua qhov chaw kub hauv kev tshawb fawb thiab tsim cov khoom ntim khoom noj.Biodegradable polymer cov ntaub ntawvtsis xav tau ib puag ncig tshwj xeeb lossis cov xwm txheej sab nraud xws li lub teeb, cua sov thiab dej hauv cov txheej txheem degradation.Lawv tsuas yog yuav tsum tau siv cov kab mob me me los tsim cov tshuaj physicochemical zoo thiab thaum kawg tsim cov pa roj carbon dioxide.Txhua yam khoom tsim los ntawm cov tshuaj tiv thaiv degradation yuav tsis tsim cov pa phem thiab ua rau muaj kev hem thawj me ntsis rau tib neeg kev noj qab haus huv.

Muaj peb hom tseem ceeb ntawmbiodegradablecov ntaub ntawv polymer.Ib qho yog cov ntaub ntawv polymer uas tsim los ntawm cov kab mob, uas feem ntau tau los ntawm microbial fermentation, thiab cov neeg sawv cev feem ntau yog polyhydroxybutyrate, uas muaj cov khoom zoo biodegradation.Txawm li cas los xij, cov nqi tsim khoom thiab cov nqi ntawm cov ntaub ntawv zoo li no yog qhov siab, thiab lawv tsis tshua muaj siv hauv kev tsim khoom tshwj xeeb.Qhov thib ob yog cov khoom siv hluavtaws polymer.Tam sim no, feem ntau siv cov khoom siv hluavtaws polymer hauv Suav lag luam yog polyvinyl cawv thiab polycaprolactone.Ntawm lawv, polycaprolactone yog dav siv hauv ntim khoom noj.Qhov thib peb yog natural polymer cov ntaub ntawv.Cov khoom siv ntuj tsim muaj xws li cellulose, starch, protein, thiab chitosan ua cov ntaub ntawv matrix.Tom qab siv rau ib lub sijhawm, cov ntaub ntawv polymer ntuj tuaj yeem degraded zoo thiab tsis muaj kev cuam tshuam rau sab nraud ecological ib puag ncig.tej kev ua qias tuaj.
Biodegradablepolymers yog ib qho ntawm cov khoom siv tshiab tshaj plaws hauv kev ntim khoom.Biodegradable polymers muaj qhov zoo ntawmdav qhov chaw, recyclability, ib puag ncig tiv thaiv thiab tsis muaj kuab paug,tab sis biopolymers muaj qee qhov kev txwv ntawm kev ua kom sov, oxygen thiab dej vapor barrier zog, nqi thiab cov khoom siv kho tshuab.Yog li ntawd, kev tshawb fawb ntawm cov khoom ntim no yuav tsum tau ua kom tob ntxiv txhawm rau txhim kho lub txee lub neej, khoom noj muaj txiaj ntsig thiab microbial kev nyab xeeb ntawm zaub mov.
Yog li ntawd, ntau thiab ntau lub tuam txhab tau pib tsim cov ntim khoom ua los ntawm cov khoom siv biodegradable, ua raws li cov qauv ntawm lub sijhawm thiab hloov mus rau kev lag luam tshiab.
