Inkcazo:

Ukususela ekufunyanweni kwazo ngowe-1991, iicarbon nanotubes ziye zathandwa ngabaphandi kwimichiza, iphysics, nenzululwazi yezixhobo.Nangona kunjalo, ngenxa yokuba i-carbon nanotubes ilula kakhulu ukuhlanganisana, ayisasazwa lula kwi-bottleneck kwizicelo eziphathekayo.Ukuguqulwa kweekhemikhali zomphezulu we-carbon nanotubes ukuphucula iipropati zabo zomphezulu yindlela esebenzayo yokuvula le bhotile.Indlela yokuguqulwa kweekhemikhali kukwenza ukusabela kweekhemikhali phakathi kwe-carbon nanotubes kunye ne-modifier ukutshintsha isakhiwo sobuso kunye nesimo se-carbon nanotubes, ukuze kufezekiswe injongo yokuguqulwa.Enye yezona ziqhelekileyo zisetyenziswa ziiasidi ezomeleleyo okanye iiasidi ezixubeneyo ukwenza i-oxidize iziphene kumphezulu we-carbon nanotubes ukwenza amaqela e-carboxyl.

I-COOH Multi Walled Carbon Nanotubes ingasetyenziswa kwizinto ezidibeneyo zokuphucula ukusebenza kwazo.Oku kulandelayo ngamanye amaphepha kunye neziphumo zophando zokukhangela:

Njenge-agent e-heterogeneous nucleating agent, i-CNT-COOH inciphisa ubungakanani obuqhelekileyo beeseli ze-phenolic foam kunye nokwandisa ubuninzi beeseli;njengoko umxholo we-CNTCOOH kwi-foam ye-phenolic yanda, i-modulus yoxinzelelo kunye nokunyanzeliswa kwe-CNT-COOH / phenolic foam composite Amandla anyuka.

Emva kokuguqulwa kwe-carboxylation ye-MWCNTs, ukusabalalisa kwi-matrix ye-ABS kuphuculwe, kwaye ukuzinza kuphuculwe.Ngexesha elifanayo, iipropathi zemishini ye-ABS / MWCNTs-COOH yezinto ezidibeneyo nazo ziphuculwe, kwaye amandla okuqina nawo aphuculwe.Kwinkqubo, i-network carbon layer iya kwenziwa phezu kwezinto eziphathekayo ukuphucula ukusebenza kwe-flame retardant yezinto ezidibeneyo.

Imeko yoGcino:

COOH Functionalized MWCNT Short kufuneka itywinwe kakuhle, igcinwe kwindawo epholileyo, eyomileyo, igweme ukukhanya okuthe ngqo.Ukugcinwa kobushushu begumbi kulungile.
