1. Kev ruaj khov thiab cov khoom siv hauv eco
Biodegradable plastics: muaj kev loj hlob hloov mus rau biodegradable xws li Pla (polyhydroxyates) kom txo cov kev cuam tshuam ib puag ncig.
Cov cuab yeej siv ua dua tshiab: Kev siv ntau tshaj plaws thermoplastics zoo li tsiaj (polyethylene terephthalate) thiab siv tau yooj yim txheej txheem ntws.
Cov ntawv sau ua hlaws: Kev loj hlob ntawm daim ntawv lossis cov cellulose-raws li cov ntaub ntawv bluister cov ntaub ntawv ua ib qho kev xaiv rau cov teeb meem tsoosics, muab cov kev xaiv kom muaj kev xaiv ntau dua.
Cov khoom siv xyoob xyoob ntoo polymers: cov khoom siv los ntawm cov peev txheej tshiab xws li corningarch, kab tsib, lossis alo-phooj ywg xaiv.
2. Kev thaiv kev loj heev
High-brier Films: Txhim Kho Cov Khoom Siv Barrier los tiv thaiv cov khoom lag luam rhiab (piv txwv li, khoom noj khoom haus, zaub mov noo, oxygen, thiab UV teeb. Piv txwv suav nrog evoh (ethylene vinyl cawv) thiab txhuas raws cov yeeb yaj kiab.
Nanocomposites: kev koom tes ntawm Nanotechnology los tsim cov ntaub ntawv nrog cov khoom siv zoo dua, lub zog, thiab cov yam ntxwv me me.
Cov yeeb yaj kiab txheej: kev siv cov ntaub ntawv muaj ntau txheej uas ua ke sib txawv polymers kom ua tiav kev tiv thaiv zoo thiab kev ua tau zoo.
3. Lub teeb yuag thiab cov khoom siv nyias nyias
Txo cov khoom siv siv: kev loj hlob ntawm thinner tsis muaj zog cov ntaub ntawv los txo cov nqi pov tseg thiab txo tus nqi thaum tswj hwm durability thiab kev tiv thaiv tsis taus thiab tiv thaiv.
Kev Xaiv Txawv: Kev txais yuav cov teeb polymers uas txo cov nqi tsheb thauj mus los thiab cov roj carbon.
4. Nqi siv tau zoo thiab cov kev daws teeb meem
Txoj kev xaiv polymers: kev tshawb nrhiav cov nqi polymers zoo li pp (polypropylene) lossis PE (Polyethylene) lossis lwm yam rau cov khoom kim kim.
Kev siv suab nrov hauv zos: Siv cov khoom noj nyob hauv zos los txo cov nqi thiab cov kab ke paab uas cuam tshuam nrog kev thauj mus los.
