Inkqubela phambili yoPhando lwamva nje lweCarbon Dioxide Polyether Polyols eTshayina

Izazinzulu zaseTshayina zenze inkqubela phambili enkulu kwicandelo lokusetyenziswa kwekhabhoni diokside, kwaye uphando lwamva nje lubonisa ukuba iTshayina iphambili kuphando malunga nekhabhoni diokside polyether polyols.

Iipolyol ze-polyether ze-carbon dioxide luhlobo olutsha lwezinto ze-biopolymer ezinamathuba amaninzi okusetyenziswa kwimarike, ezifana nezixhobo zokukhusela izakhiwo, i-oyile yokubhola i-foil, kunye nezinto ze-biomedical. Izinto zayo eziphambili yi-carbon dioxide, ukusebenzisa i-carbon dioxide ngokukhetha kunokunciphisa ngempumelelo ungcoliseko lokusingqongileyo kunye nokusetyenziswa kwamandla e-fossil.

Kutshanje, iqela lophando elivela kwiSebe leKhemistri kwiYunivesithi yaseFudan liphumelele ukwenza i-polymer yeqela le-carbonate eline-alcohol eninzi kunye ne-carbon dioxide ngokusebenzisa iteknoloji ye-infiltration catalytic reaction ngaphandle kokongezwa kweziqinisi zangaphandle, kwaye lalungiselela izinto ze-polymer eziphezulu ezingafunekiyo unyango emva koko. Kwangaxeshanye, izinto zinozinzo oluhle lobushushu, ukusebenza kakuhle kokucubungula, kunye neempawu zoomatshini.

Kwelinye icala, iqela elikhokelwa yingcali yezemfundo uJin Furen likwazile ukwenza ngempumelelo i-ternary copolymerization reaction ye-CO2, i-propylene oxide, kunye ne-polyether polyols ukulungiselela izinto ezine-polymer ephezulu ezinokusetyenziselwa ukwakha izixhobo zokukhusela. Iziphumo zophando zicacisa ukuba kunokwenzeka ukudibanisa ngempumelelo ukusetyenziswa kweekhemikhali ze-carbon dioxide kunye nee-polymerization reactions.

Ezi ziphumo zophando zibonelela ngeengcinga ezintsha kunye nezikhokelo zobuchwepheshe bokulungiselela izinto ze-biopolymer eTshayina. Ukusebenzisa iigesi zenkunkuma yemizi-mveliso ezifana ne-carbon dioxide ukunciphisa ungcoliseko lokusingqongileyo kunye nokusetyenziswa kwamandla e-fossil, kunye nokwenza yonke inkqubo yezinto ze-polymer eziphezulu ukusuka kwizinto eziluhlaza ukuya ekulungiseleleni "luhlaza" nako kukwindlela yexesha elizayo.

Ukuqukumbela, impumelelo yophando lwaseTshayina kwi-carbon dioxide polyether polyols inomdla, kwaye kufuneka uphando olongezelelweyo kwixesha elizayo ukuze olu hlobo lwezinto ze-polymer eziphezulu lusetyenziswe kakhulu kwimveliso nasebomini.
