Isizinda Socwaningo
Izinto zokushintsha izigaba (ama-PCM) zisetshenziswa kakhulu ekwakheni ukulawulwa kwezinga lokushisa, ukusetshenziswa kabusha kokushisa kwemfucuza kanye nokuchithwa kokushisa emikhiqizweni ye-elekthronikhi ngenxa yobungane bemvelo kanye nokusimama. Phakathi kwezinhlobo ezihlukahlukene zama-PCM, ama-PCM aphilayo (ama-OPCM) afana ne-polyethylene glycol (PEG) ne-parafini wax ane-enthalpy ephakeme yokuguqulwa kwesigaba, uhla lokushisa lokushintsha kwesigaba olufaneleka kakhulu, ukugqwala okuphansi, ukungabi nobuthi kanye nokuzinza okungcono kokushisa, ngakho-ke kuvame ukusetshenziswa kakhulu kunezinye izinhlobo ze-PCM. Kodwa-ke, i-thermal conductivity ephansi kanye nokuthambekela kokuvuza ngaphezu kwendawo encibilikayo yama-OPCM kuyizithiyo ezingathi sína ekusetshenzisweni kwawo kwesilinganiso esikhulu. Ngenxa yalokho, amathimba enze ucwaningo olunzulu mayelana nalezi zinkinga.
Isingeniso Sesihloko
Muva nje, inoveli ye-carbonized melamine foam/encishisiwe i-graphene oxide coated copper network (MF/rGO/Cu-C) ilungiswe nguProf. Zou Yongjin kanye neqembu likaProf. Sun Lixian e-Guilin University of Electronic Science and Technology ukuze kwakhiwe ama-OPCM azinzile asebenza ngezindlela eziningi. I-PEG ikhethwe njengendawo yokugcina eshisayo futhi ama-OPCM ayinhlanganisela (PEG@MF/rGO/Cu-C) alungiswe esihlokweni ngokufakwa kwe-vacuum. I-peG@MF/rGO/Cu-C ine-enthalpy encibilika ephezulu (148.3 J g-1) kanye ne-crystallization enthalpy (143.9 J g-1). Ngaphezu kwalokho, ukusebenza kwayo okushisayo kufinyelele ku-0.4621 W m-1K-1, ukuthuthuka okungama-463% uma kuqhathaniswa ne-PEG@MF. Ama-OPCM ayinhlanganisela aphinde abonise izakhiwo ezinhle kakhulu zokuguqula isithombe-ezishisayo kanye ne-electro-thermal ngakho-ke anamandla okusebenzisa izigwegwe eziningi.
Ukuhlaziywa Kwezithombe
- i-GO ilayishwe kuhlaka lwe-3D lwe-MF(melamine foam) ngokufakwa kwesisombululo ukuze kutholwe inethiwekhi ye-MF/GO; ke, i-MF/GO ifakwe ithusi ngamakhemikhali futhi i-GO iyancipha ngesikhathi esisodwa ngesikhathi senqubo yokucwenga yethusi ukuze ithole i-MF/rGO/Cu; bese, inethiwekhi ye-MF/rGO/Cu ifakwe nge-carbonised kumazinga okushisa aphezulu ukuze ithole i-MF/rGO/Cu-C; ekugcineni, i-PEG ivacuum efakwe kuyo yalayishwa ku-MF/rGO/Cu-C ukuze kutholwe ama-OPCM ayinhlanganisela ye-PEG@MF/MF/rGO/Cu-C.
- I-morphology yezinto ezibonakalayo yabonwa kusetshenziswa i-SEM. isenzo sokulingisa se-MF siholele ku-MF/GO, MF/rGO/Cu kanye ne-MF/rGO/Cu-C zonke zibe nesakhiwo se-3D esinezikhala ezinezikhala ezifanayo. Ngaphezu kwalokho, ukulayisha ngempumelelo kwezinhlayiya ze-Cu kungabonwa ezithombeni ze-SEM.
- Imiphumela yokuhlaziywa kwe-XRD, FT-IR kanye ne-XPS ikhombisa ukulayishwa ngempumelelo kwezinhlayiya zethusi kanye nokwehliswa ngempumelelo kwe-GO.
- Ukushintsha kwesigaba sokuziphatha kwama-OPCM kwaphenywa kusetshenziswa i-DSC. Amajika e-DSC awo wonke ama-OPCM ayinhlanganisela ayefana nalawo e-PEG ehlanzekile, equkethe inani eliphakeme lokuncibilika kanye nenani eliphakeme lokucwebezela, okubonisa ukuthi ukwethulwa komthwali akuzange kuguqule ukuziphatha kwe-crystallization kwe-PEG. Ngaphezu kwalokho, ukwethulwa kwe-rGO ne-Cu kanye nokwelashwa kwe-carbonisation kuthuthukise ukuqhutshwa kokushisa kwenethiwekhi.
- I-PEG@MF/rGO/Cu-C inamandla amahle kakhulu okuguqula isithombe kanye ne-electro-thermal.
