Imvelaphi yophando
Izinto zokutshintsha iSigaba (PCMs) zisetyenziswa ngokubanzi ekulawuleni ubushushu bokwakha, ukuphinda kusetyenziswe ubushushu obumdaka kunye nokutshatyalaliswa kobushushu kwiimveliso ze-elektroniki ngenxa yobungane bemekobume kunye nokuzinza. Phakathi kweentlobo ezahlukeneyo ze-PCMs, ii-PCM eziphilayo (i-OPCMs) ezifana ne-polyethylene glycol (PEG) kunye ne-wax yeparafini ine-enthalpy ephezulu yokutshintsha kwesigaba, ukutshintshwa kwesigaba esifanelekileyo sokutshintsha kweqondo lokushisa, ukubola okuphantsi, ukungabikho kwetyhefu kunye nokuzinza okungcono kwe-thermal, kwaye ngoko ke isetyenziswa ngokuqhelekileyo kunezinye iintlobo ze-PCM. Nangona kunjalo, i-thermal conductivity ephantsi kunye nokuthambekela kokuvuza ngaphezu kwendawo yokunyibilika kwee-OPCM zizithintelo ezinzulu kwisicelo sazo esikhulu. Ngenxa yoko, amaqela enze uphando olubanzi malunga nale miba.
Intshayelelo yenqaku
Kutshanje, inoveli ye-carbonized melamine foam/encitshisiweyo yegraphene oxide coated network copper (MF/rGO/Cu-C) yalungiswa nguProf. Zou Yongjin kunye neqela likaProf Sun Lixian kwiYunivesithi yaseGuilin yeSayensi yezobuChwepheshe kunye neTekhnoloji ukulungiselela ukwakhiwa kwee-OPCM ezizinzileyo ezinemisebenzi emininzi. I-PEG ikhethwe njengento yokugcina i-thermal kunye ne-OPCMs edibeneyo (PEG @ MF / rGO / Cu-C) yalungiswa kwinqaku nge-vacuum impregnation. i-peG@MF/rGO/Cu-C ine-enthalpy ephezulu yokunyibilika (148.3 J g-1) kunye ne-crystallization enthalpy (143.9 J g-1). Ukongezelela, i-thermal conductivity yayo ifikelele kwi-0.4621 W m-1K-1, ukuphuculwa kwe-463% xa kuthelekiswa ne-PEG@MF. I-OPCMs edibeneyo iphinda ibonise iimpawu ezibalaseleyo ze-photo-thermal kunye ne-electro-thermal conversion kwaye ngoko ke zinamandla okusetyenziswa kwezinto ezininzi.
Uhlalutyo lwemizobo
- i-GO ilayishwe kwi-MF (melamine foam) isakhelo se-3D ngokufaka isisombululo ukufumana inethiwekhi ye-MF / GO; emva koko, i-MF / GO ifakwe iikhemikhali zethusi kwaye i-GO iyancitshiswa ngaxeshanye ngexesha lenkqubo yokubeka ubhedu ukufumana i-MF / rGO / Cu; emva koko, inethiwekhi ye-MF/rGO/Cu ifakwe kwi-carbonised kwiqondo lokushisa eliphezulu ukufumana i-MF/rGO/Cu-C; ekugqibeleni, i-PEG ivacuum ifakwe kwi-MF/rGO/Cu-C ukufumana i-PEG@MF/MF/rGO/Cu-C ii-OPCM ezihlanganisiweyo.
- I-morphology yezinto eziphathekayo yabonwa kusetyenziswa i-SEM. isenzo se-templates se-MF sibangele i-MF / GO, MF / rGO / Cu kunye ne-MF / rGO / Cu-C zonke zinesakhiwo esifanayo se-3D se-mesh. Ukongezelela, ukulayishwa okuyimpumelelo kwee-Cu particles kunokubonwa kwimifanekiso ye-SEM.
- Iziphumo ze-XRD, i-FT-IR kunye ne-XPS zihlalutya zibonisa ukulayishwa okuyimpumelelo kwamasuntswana obhedu kunye nokunciphisa ngempumelelo kwe-GO.
- Ukuziphatha kokutshintsha kwesigaba se-OPCMs kwaphandwa kusetyenziswa i-DSC. Iingqungquthela ze-DSC zazo zonke ii-OPCM ezidibeneyo zifana ne-PEG ecocekileyo, equlethe i-melting peak kunye ne-crystallization peak, ebonisa ukuba ukuqaliswa komthwali akuzange kutshintshe ukuziphatha kwe-crystallization ye-PEG. Ukongezelela, ukuqaliswa kwe-rGO kunye neCu kunye ne-carbonisation unyango luphucule ukuqhutyelwa kwe-thermal yenethiwekhi.
- I-PEG@MF/rGO/Cu-C ineefoto ezibalaseleyo kunye ne-electro-thermal conversion capabilities.
