Intuthuko Yocwaningo Lwakamuva Lwe-Carbon Dioxide Polyether Polyols eShayina

Ososayensi baseShayina benze intuthuko enkulu emkhakheni wokusetshenziswa kwe-carbon dioxide, kanti ucwaningo lwakamuva lubonisa ukuthi iShayina ihamba phambili ocwaningweni ngama-polyol e-polyether e-carbon dioxide.

Ama-polyol e-polyether e-carbon dioxide awuhlobo olusha lwezinto ze-biopolymer ezinamathuba amaningi okusetshenziswa emakethe, njengezinto zokwakha zokushisa, i-foam yokubhoboza uwoyela, kanye nezinto ze-biomedical. Izinto zayo eziyinhloko zokusetshenziswa yi-carbon dioxide, ukusebenzisa i-carbon dioxide ngokukhetha kunganciphisa ngempumelelo ukungcola kwemvelo kanye nokusetshenziswa kwamandla asele.

Muva nje, ithimba locwaningo elivela eMnyangweni Wekhemistri eFudan University liphumelele ukwenza i-polymer yeqembu le-carbonate eliqukethe utshwala obuningi nge-carbon dioxide ngokusebenzisa ubuchwepheshe bokusabela kwe-catalytic infiltration ngaphandle kokwengeza iziqinisi zangaphandle, futhi lalungisa izinto ze-polymer eziphezulu ezingadingi ukwelashwa ngemuva. Ngesikhathi esifanayo, izinto zizinzile kahle ekushiseni, ukusebenza kahle kokucubungula, kanye nezakhiwo zemishini.

Ngakolunye uhlangothi, ithimba eliholwa yisazi uJin Furen nalo lenze ngempumelelo ukusabela kwe-ternary copolymerization kwe-CO2, i-propylene oxide, kanye ne-polyether polyols ukulungiselela izinto ze-polymer ephezulu ezingasetshenziswa ekwakheni izinto zokushisa. Imiphumela yocwaningo icacisa ukuthi kungenzeka yini ukuhlanganisa ngempumelelo ukusetshenziswa kwamakhemikhali kwe-carbon dioxide kanye nokusabela kwe-polymerization.

Le miphumela yocwaningo inikeza imibono emisha kanye neziqondiso zobuchwepheshe bokulungiselela izinto ze-biopolymer eShayina. Ukusebenzisa amagesi emfucuza yezimboni njenge-carbon dioxide ukunciphisa ukungcola kwemvelo kanye nokusetshenziswa kwamandla angaphansi komhlaba, nokwenza yonke inqubo yezinto ze-polymer ephezulu kusukela ezintweni zokusetshenziswa kuya ekulungiseleleni "kuluhlaza" nakho kuyinkambiso yesikhathi esizayo.

Ekuphetheni, impumelelo yocwaningo lwaseShayina kuma-polyol e-carbon dioxide polyether iyajabulisa, futhi kudingeka ukuhlolwa okwengeziwe esikhathini esizayo ukuze lolu hlobo lwezinto ze-polymer ephezulu lusetshenziswe kabanzi ekukhiqizeni nasekuphileni.
