Nkwadebe na njirimara nke ihe nkiri polyimide / graphene polymer material

Dị ka akụkọ si kwuo, ụzọ nkwadebe nke ihe ndị mejupụtara polyimide / graphene bụ n’ozuzu: ngwakọta ngwọta, n’ime ọnọdụ polymerization na ngwakọta agbaze.

(1) Ngwakọta ngwọta

Ngwọta ngwakọta: Mgbe agwakọta graphene na graphene mmepụta iji chụsasịa ha na ngwọta polymer, wee wepụ ihe mgbaze ahụ, enwere ike ịkwado ihe ndị kwekọrọ na polymer nanocomposite. N’ihi na graphene nwere ihe fọrọ nke nta ka ọ bụrụ enweghị solubility, na graphene na-adịkarị mfe nchịkọta interlayer. Ya mere, ndị na-eme nchọpụta ewebatala otu ndị na-arụ ọrụ organic n’ime nhazi nke graphene iji mee ka ike nke graphene na graphene dịkwuo mma. N’ihi na graphene oxide bụ mmiri soluble, ọ nwere ike na-agwakọta ya na colloidal ngwọta na mmiri-soluble polymer aqueous ngwọta. Mgbe ịgwakọta, ultrasonic ọgwụgwọ na ịkpụzi Filiks, ihe njikere polymer / graphene oxide mejupụtara ihe nwere magburu onwe n’ibu Njirimara . N’ime nkwadebe nke graphene oxide na mmiri mmiri na-adịghị ahụ ike site na ngwakọta iji kwadebe ihe ndị mejupụtara, ọrụ organic nke graphene oxide na-enyewanye aka iji melite solubility ya na ihe ndị na-edozi ahụ na ngwakọta siri ike na polymers.

(2) polymerization n’ime ọnọdụ

Nnukwu ihe dị iche n’etiti usoro ngwakọta ngwọta na usoro in-situ polymerization bụ na a na-eme usoro nke njikọ polymer na ngwakọta nke graphene ma ọ bụ graphene n’otu oge, na ụdọ polymer guzobere site na polymerization na graphene ma ọ bụ graphene. Mwepụta nwere ọdịdị dị iche iche. Mmetụta covalent siri ike. Ihe mejupụtara polymer / graphene nke usoro a nwetara nwere mmetụta interface siri ike karị, ya mere arụ ọrụ izugbe ya emeela ka ọ dịkwuo mma. N’ime ha, ihe ndị mejupụtara polymer / graphene a kwadebere site na iji nylon-6, polystyrene, epoxy resin, wdg dị ka polymer matrix bụ ihe niile a kwadebere site na polymerization in-site.

(3) Agbazekwa ngwakọta

N’ime usoro ịgbaze agbaze, enwere ike ịkwadebe ihe mejupụtara polymer / graphene na-enweghị ihe mgbaze. Ọ dị mkpa ka ịgwakọta graphene ma ọ bụ graphene mmepụta na polima na steeti a wụrụ awụ n’okpuru mmetụta nke okpomọkụ dị elu na ike ịkwa akwa. A na-akọ na a kwadebere ụdị polymers dị iche iche (dị ka polyester na polycarbonate, polyethylene 2,6-naphthalate) / ihe ndị mejupụtara graphene na-arụ ọrụ site na ngwakọta agbaze. Agbalịkwara m ịgbaze na ngwakọta nke polylactic acid/graphene na ihe polyethylene terephthalate/graphene. Ọ bụ ezie na usoro a nwere ike ịghọta nnukwu nkwadebe n’agbanyeghị na ọ na-arụ ọrụ dị mfe, mpempe akwụkwọ graphene na-agbaji n’ihi mmetụta ike dị elu n’oge usoro nkwadebe.
