Shiri da halaye na polyimide fim / graphene polymer abu
Shiri da halaye na polyimide fim / graphene polymer abu
A cewar rahotanni, hanyoyin shirye-shiryen kayan haɗin gwiwar polyimide / graphene gabaɗaya sune: haɗaɗɗen bayani, polymerization a cikin wurin da narke haɗuwa.
(1) Magani gauraye
Magani gauraye: Bayan hadawa graphene da graphene Kalam don tarwatsa su a cikin wani polymer bayani, sa’an nan cire sauran ƙarfi, da m polymer nanocomposite kayan za a iya shirya. Saboda graphene kusan ba shi da solubility, kuma graphene yana da saurin haɗuwar interlayer. Sabili da haka, masu bincike sun gabatar da ƙungiyoyi masu aiki na kwayoyin halitta a cikin tsarin graphene don ƙara yawan solubility na graphene da graphene. Saboda graphene oxide yana da ruwa mai narkewa, ana iya haɗa shi kai tsaye tare da maganin colloidal da maganin ruwa mai narkewar ruwa. Bayan hadawa, ultrasonic jiyya da gyare-gyaren tafiyar matakai, da shirye polymer / graphene oxide composite abu yana da kyau kwarai inji Properties . A cikin shirye-shiryen graphene oxide da polymers da ba za a iya narkewa ba ta hanyar haɗuwa don shirya kayan haɗin gwiwa, aikin kwayoyin halitta na graphene oxide yana ƙara taimakawa wajen inganta narkewa a cikin kwayoyin halitta da haɗin gwiwa tare da polymers.
(2) In-wuri polymerization
Bambanci mafi girma tsakanin hanyar haɗakarwar mafita da hanyar polymerization a cikin wurin shi ne cewa ana aiwatar da tsarin haɗin polymer da haɗar abubuwan graphene ko graphene a lokaci guda, da kuma sarƙoƙin polymer da aka samar ta hanyar polymerization da graphene ko graphene. abubuwan da aka samu suna da kamanni daban-daban. Tasirin haɗin gwiwa mai ƙarfi. Abubuwan da aka haɗe na polymer/graphene da aka samu ta wannan hanyar yana da tasiri mai ƙarfi mai ƙarfi, don haka aikin gamammenta ya inganta sosai. Daga cikin su, kayan haɗin polymer / graphene da aka shirya ta amfani da nailan-6, polystyrene, resin epoxy, da dai sauransu kamar yadda matrix polymer duk an shirya su ta hanyar polymerization a cikin wuri.
(3) Narke hadawa
A cikin tsari na narkewa, ana iya shirya kayan haɗin polymer / graphene ba tare da kaushi ba. Yana buƙatar kawai haɗa nau’ikan graphene ko graphene da polymer a cikin narkakkar da ke ƙarƙashin tasirin babban zafin jiki da ƙarfi mai ƙarfi. An ba da rahoton cewa an shirya nau’ikan polymers (irin su polyester da polycarbonate, polyethylene 2,6-naphthalate) / kayan aikin graphene mai haɗawa da kayan aikin da aka shirya ta hanyar narkewar narke. Na kuma gwada hadawa da hadawa na polylactic acid/graphene da polyethylene terephthalate/graphene kayan. Ko da yake wannan hanya na iya gane manyan shirye-shirye duk da sauƙin aiki, takardar graphene ta karye saboda tasirin ƙarfin ƙarfi a lokacin shirye-shiryen.
