Ukulungiswa kanye nezici ze-polyimide film/graphene polymer material

Ngokwemibiko, izindlela zokulungiselela zezinto eziyinhlanganisela ye-polyimide/graphene ngokuvamile yilezi: ukuxuba isixazululo, i-in-situ polymerization kanye nokuncibilika kokuncibilika.

(1) Ukuhlanganisa isixazululo

Ukuxuba Isixazululo: Ngemva kokuxuba i-graphene ne-graphene derivatives ukuze uzihlakaze ngesisombululo se-polymer, bese ususa i-solvent, izinto ezihambisanayo ze-polymer nanocomposite zingalungiswa. Ngoba i-graphene cishe ayinakho ukunyibilika, futhi i-graphene ithambekele ekuhlanganisweni kwe-interlayer. Ngakho-ke, abacwaningi bethule amaqembu asebenzayo e-organic esakhiweni se-graphene ukwandisa ukunyibilika kokuphuma kwe-graphene kanye ne-graphene. Ngenxa yokuthi i-graphene oxide ayincibiliki emanzini, ingaxutshwa ngokuqondile nesisombululo sayo se-colloidal kanye nesisombululo samanzi se-polymer esincibilika emanzini. Ngemuva kokuxuba, ukwelashwa kwe-ultrasonic kanye nezinqubo zokubumba, i-polymer/graphene oxide composite material elungiselelwe inezakhiwo ezinhle kakhulu zemishini. Ekulungiseni i-graphene oxide nama-polymers angancibiliki emanzini ngokuxubana ukuze kulungiswe izinto eziyinhlanganisela, umsebenzi we-organic we-graphene oxide uya ngokuya usiza ukuthuthukisa ukunyibilika kwawo kuzinyibilikisi ze-organic kanye nenhlanganisela eqinile nama-polymers.

(2) I-in-situ polymerization

Umehluko omkhulu phakathi kwendlela yokuhlanganisa isixazululo kanye nendlela ye-polymerization ye-in-situ ukuthi inqubo ye-polymer synthesis kanye nokuxutshwa kokuphuma kwe-graphene noma kwe-graphene kwenziwa ngesikhathi esifanayo, kanye namaketanga e-polymer akhiwe yi-polymerization ne-graphene noma i-graphene. okuphuma kokunye kunokubukeka okuhlukile. Umphumela webhondi ye-covalent enamandla. I-polymer/graphene composite material etholwe yile ndlela inomphumela oqinile wokusebenzisana, ngakho-ke umsebenzi wayo wokuhlanganisa uthuthukiswe kakhulu. Phakathi kwazo, izinto eziyinhlanganisela ye-polymer/graphene ezilungiselelwe kusetshenziswa inayiloni-6, i-polystyrene, i-epoxy resin, njll. njengoba i-matrix ye-polymer konke kulungiswe nge-in-situ polymerization.

(3) Ncibilikisa ukuxutshwa

Enqubweni yokuncibilika kokuncibilika, i-polymer/graphene composite material ingalungiswa ngaphandle kwezinyibilikisi. Idinga kuphela ukuxuba okuphuma kokuphuma kwe-graphene noma kwe-graphene kanye ne-polymer esimweni esincibilikisiwe ngaphansi komphumela wokushisa okuphezulu namandla aphezulu okugunda. Kubikwa ukuthi ama-polymers ahlukahlukene (afana ne-polyester ne-polycarbonate, i-polyethylene 2,6-naphthalate)/izinto ezisebenzayo ze-graphene composite zilungiselelwe ngokuxutshwa kokuncibilika. Ngiphinde ngazama ukuncibilika nokuhlanganisa izinto ze-polylactic acid/graphene kanye ne-polyethylene terephthalate/graphene. Nakuba le ndlela ingakwazi ukubona ukulungiswa okukhulu naphezu kokusebenza kwayo okulula, ishidi le-graphene liphukile ngenxa yomphumela omkhulu we-shear force ngesikhathi senqubo yokulungiselela.
