Kutsvagisa kumashure
Phase shanduko zvinhu (PCMs) anoshandiswa zvakanyanya mukuvaka kudzora tembiricha, tsvina kupisa kushandiswa zvakare uye kupisa kupisa muzvigadzirwa zvemagetsi nekuda kwehushamwari hwavo kwezvakatipoteredza uye kusimba. Pakati pemhando dzakasiyana-siyana dzePCMs, organic PCMs (OPCMs) yakadai se polyethylene glycol (PEG) uye parafini wax ine enthalpy yepamusoro yekuchinja kwechikamu, inonyanya kukodzera chikamu chekuchinja kwekushisa, kuderera kwekuora, kusina-chepfu uye kugadzikana kwekupisa, uye naizvozvo inonyanya kushandiswa kupfuura mamwe marudzi ePCM. Nekudaro, iyo yakaderera yekushisa conductivity uye tsika yekudonha pamusoro penzvimbo yekunyungudika yeOPCM zvipingamupinyi zvakakomba pakushandisa kwavo kukuru. Nekuda kweizvozvo, zvikwata zvakaita tsvakiridzo yakakura maererano nenyaya idzi.
Chinyorwa Nhanganyaya
Munguva ichangopfuura, bhuku rinonzi carbonized melamine foam/ rakaderedzwa graphene oxide coated copper network (MF/rGO/Cu-C) rakagadzirirwa naProf. Zou Yongjin neboka raProf. Sun Lixian paGuilin University of Electronic Science and Technology nokuda kwekuvaka kwakagadzikana multifunctional OPCMs. PEG yakasarudzwa sechinhu chekuchengetera chemafuta uye maOPCM anoumbwa (PEG@MF/rGO/Cu-C) akagadzirirwa muchinyorwa nevacuum impregnation. pEG@MF/rGO/Cu-C ine yakakwira kunyungudika enthalpy (148.3 J g-1) uye crystallization enthalpy (143.9 J g-1). Pamusoro pezvo, kupisa kwayo kwakasvika pa0.4621 W m-1K-1, kuvandudzwa kwe463% zvichienzaniswa nePEG@MF. Iwo akaumbwa maOPCM anoratidzawo yakanakisa mafoto-thermal uye electro-thermal kutendeuka zvivakwa uye saka ane mukana weakawanda-kuranga maapplication.
Graphic Analysis
- iyo GO inotakurwa muMF (melamine foam) 3D chimiro nemhinduro yekumisikidza kuwana iyo MF/GO network; zvino, MF / GO ikemikari mhangura yakaputirwa uye GO inoderedzwa panguva imwe chete panguva yemhangura yemhangura kuti iwane MF / rGO / Cu; ipapo, iyo MF/rGO/Cu network inoiswa carbonised pakupisa kwakanyanya kuwana MF/rGO/Cu-C; pekupedzisira, iyo PEG is vacuum yakaiswa mukati yakaiswa muMF/rGO/Cu-C kuwana PEG@MF/MF/rGO/Cu-C inoumba OPCMs.
- Iyo morphology yezvinhu yakaonekwa uchishandisa SEM. iyo templating action yeMF yakakonzera MF/GO, MF/rGO/Cu uye MF/rGO/Cu-C ese aine akafanana 3D porous mesh chimiro. Mukuwedzera, kurodha kwakabudirira kweCu particles kunogona kuonekwa kubva kuSEM mifananidzo.
- Mhedzisiro yeXRD, FT-IR uye XPS ongororo inoratidza kubudirira kurodha zvimedu zvemhangura uye kudzikisira kwakabudirira kweGO.
- Chikamu chekuchinja maitiro eOPCMs chakaongororwa pachishandiswa DSC. DSC curves yeOPCMs yose yakasanganiswa yakanga yakafanana neye PEG yakachena, ine peak yakanyunguduka uye crystallization peak, zvichiratidza kuti kuiswa kwemutakuri hakuna kuchinja maitiro ekristallisation ePEG. Uye zvakare, kuunzwa kweRGO neCu uye kurapwa kwecarbonisation kwakavandudza kupisa kweiyo network.
- PEG@MF/rGO/Cu-C ine yakanakisa foto- uye electro-thermal kutendeuka masimba.
SINOYQX inogamuchira tsamba nenhare kubva kumayunivhesiti, masangano ekutsvagisa sainzi nemabhizinesi pasi rose.
