Inqubekelaphambili Yocwaningo Yakamuva Ye-Carbon Dioxide Polyether Polyols e-China

Ososayensi baseShayina benze intuthuko enkulu emkhakheni wokusetshenziswa kwe-carbon dioxide, futhi ucwaningo lwakamuva lubonisa ukuthi i-China ihamba phambili ocwaningweni lwe-carbon dioxide polyether polyols.

I-Carbon dioxide polyether polyols iwuhlobo olusha lwempahla ye-biopolymer enamathemba abanzi okusetshenziswa emakethe, njengezinto zokwakha, igwebu lokumba uwoyela, nezinto ze-biomedical. Izinto ezisetshenziswayo eziyinhloko yi-carbon dioxide, ngokukhetha ukusebenzisa isikhutha kunganciphisa ngempumelelo ukungcoliswa kwemvelo kanye nokusetshenziswa kwamandla ezinsalela.

Muva nje, ithimba labacwaningi eliphuma eMnyangweni Wezekhemikhali waseFudan University ngempumelelo lenze i-polymerized i-multi-alcohol equkethe i-carbonate group ne-carbon dioxide ngokusebenzisa ubuchwepheshe bokusabela obungenasici ngaphandle kokwengezwa kweziqinisi zangaphandle, futhi lalungiselela ukwaziswa okuphezulu kwe-polymer okungadingi i-post- ukwelashwa. Ngesikhathi esifanayo, impahla inokuqina okuhle kokushisa, ukusebenza kokucubungula, kanye nezakhiwo zemishini.

Ngakolunye uhlangothi, ithimba eliholwa yi-academician u-Jin Furen liphinde laphumelela ngempumelelo ukusabela kwe-ternary copolymerization ye-CO2, i-propylene oxide, nama-polyether polyols ukuze kulungiswe izinto eziphakeme ze-polymer ezingasetshenziselwa izinto zokuvikela izakhiwo. Imiphumela yocwaningo icacisa ukuthi kungenzeka yini ukuhlanganisa ngempumelelo ukusetshenziswa kwamakhemikhali kwe-carbon dioxide nokusabela kwe-polymerization.

Le miphumela yocwaningo ihlinzeka ngemibono emisha nezikhombisi-ndlela zobuchwepheshe bokulungiselela bezinto ezibonakalayo ze-biopolymer e-China. Ukusebenzisa amagesi emfucumfucu yezimboni njenge-carbon dioxide ukunciphisa ukungcoliswa kwemvelo kanye nokusetshenziswa kwamandla ezinto ezimbiwa phansi, nokwenza yonke inqubo yezinto eziphezulu ze-polymer kusukela ezintweni ezingavuthiwe kuya ekulungiseleleni "okuluhlaza" nakho kuwumkhuba wesikhathi esizayo.

Sengiphetha, impumelelo yocwaningo lwaseShayina nge-carbon dioxide polyether polyols iyajabulisa, futhi ukuhlola okwengeziwe kuyadingeka esikhathini esizayo ukuze lolu hlobo lwezinto eziphezulu ze-polymer zisetshenziswe kabanzi ekukhiqizeni nasekuphileni.
