Diyaarinta iyo sifooyinka polyimide film / graphene polymer walxaha

Sida laga soo xigtay warbixinnada, hababka diyaarinta ee walxaha isku dhafan ee polyimide/graphene waa guud ahaan: isku-dhafka xalalka, polymerization-ka gudaha iyo isku-dhafka dhalaalka.

(1) Isku dhafka xalka

Isku darka xalalka: Ka dib marka la isku daro graphene iyo graphene devatives si ay ugu kala firdhiyaan xal polymer ah, ka dibna ka saaraan dareeraha, walxaha polymer nanocomposite ee u dhigma ayaa la diyaarin karaa. Sababtoo ah graphene ma laha wax milmi ah, iyo graphene waxay u nugul yihiin isku-darka isku-darka. Sidaa darteed, cilmi-baarayaashu waxay soo bandhigeen kooxo shaqeynaya organic qaab dhismeedka graphene si loo kordhiyo milanka graphene iyo graphene devatives. Sababtoo ah graphene oxide waa biyo-milmi kara, waxay si toos ah ugu milmi kartaa xalkeeda kolloidal iyo xalalka aqueous polymer-ka ee biyaha ku milma. Ka dib marka la isku daro, daaweynta ultrasonic iyo hababka qaabeynta, walxaha isku dhafan ee polymer / graphene oxide ee la diyaariyey ayaa leh sifooyin farsamo oo aad u fiican. Diyaarinta graphene oxide iyo polymers-ka-biyo-biyoodka iyada oo la isku darayo si loo diyaariyo walxaha isku dhafan, shaqada dabiiciga ah ee graphene oxide ayaa sii kordheysa caawinta si loo hagaajiyo milanka dareeraha organic iyo isku-dhafka xooggan ee polymers.

(2) polymerization gudaha goobta

Farqiga ugu weyn ee u dhexeeya habka isku-dhafka xalka iyo habka-polymerization-ka gudaha waa in habka isku-dhafka polymer-ka iyo isku-dhafka graphene ama graphene la sameeyo isku mar, iyo silsiladaha polymer ee ay sameeyeen polymerization iyo graphene ama graphene. derivatives leeyihiin muuqaalo kala duwan. Saamaynta dammaanadda covalent ee xooggan. Qalabka isku dhafan ee polymer / graphene ee lagu helay habkani wuxuu leeyahay saameyn xoog leh oo is-dhexgal ah, sidaas darteed shaqadeeda guud ayaa si weyn loo hagaajiyay. Waxaa ka mid ah, alaabta isku-dhafka ah ee polymer/graphene ee lagu diyaariyey iyadoo la adeegsanayo nylon-6, polystyrene, resin epoxy, iwm. sida matrix-ka polymer-ka ayaa dhamaantood lagu diyaariyay polymerization-ka goobta.

(3) Isku qasid dhalaalid

Habka isku-dhafka dhalaalka, maadada polymer / graphene ee isku dhafan ayaa la diyaarin karaa iyada oo aan lahayn dareere. Waxa kaliya oo ay u baahan tahay in la isku daro graphene ama graphene derivatives iyo polymer ee gobolka dhalaalka hoostiisa saamaynta heerkulka sare iyo xoogga xiirid sare. Waxaa la soo wariyay in noocyo kala duwan oo polymers ah (sida polyester iyo polycarbonate, polyetylen 2,6-naphthalate) / qalabyada isku dhafan ee graphene ee shaqeynaya lagu diyaariyey isku-dhafka dhalaalka. Waxa kale oo aan isku dayay in aan dhalaaliyo oo aan isku daro polylactic acid/graphene iyo polyetylen terephthalate/graphene. Inkasta oo habkani uu xaqiijin karo diyaarinta baaxadda weyn inkasta oo uu shaqeynayo fudud, xaashida graphene waa la jebiyey sababtoo ah saameynta xoogga sare ee xoogga inta lagu jiro habka diyaarinta.
