Kazhinji, muviri unorasikirwa ne50 muzana yekupisa kwayo nekupenya kunze kwepakati-infrared mwaranzi. Kudzikisa kurasikirwa nemwaranzi ye infrared, zano rinoshanda ndere kudzora yepakati-infrared emissivity yemucheka uye zvipfeko, kuitira kuti uone passive radiation heat (PRH) yemuviri wemunhu. Kuenzaniswa nemaitiro ekudziya echinyakare, PRH ine zvakanakira kusashandisa simba, zvakanyanya uye zvinobudirira. Nekudaro, iyo PRH yakakura yekupisa yekupisa kugona inogumira munzvimbo yekunze, kunyanya kana iri masikati neusiku uye mamiriro ekunze achinja zvakanyanya, zvakaoma kuwana kupisa kwakaringana kwemuviri wemunhu. Naizvozvo, kuvandudzwa kwezvinhu uye masisitimu anogona kunyatsopisa muviri wemunhu nenzira ine simba, zuva rese, kwakakosha kudzikamisa dambudziko remagetsi uye kudziya kwepasirese.

Kugadzirisa matambudziko aya, timu yekutsvagisa yeYunivhesiti yeZhengzhou yakashuma nzira yekudziya-yemamiriro ekunze-yemamiriro ekunze: matatu ekudziya modhi, anoti PRH isina simba rekushandisa, simba rekuchengetedza solar kupisa uye kubhadharira Joule kupisa, zvakabatanidzwa zvakabudirira mukupfeka Mxene / nanoPE. textile (12 μm) system nekuputira mutete Ti3C2Tx Mxene coating (1 μm) pane isingadhuri nanopore polyethylene (nanoPE) textile.

Mugadziriro yekugadzirira, vatsvakurudzi vakatanga polymerized layer ye polydopamine (PDA) pamusoro pemucheka we nanoPE in situ kuti iite hydrophilic pamusoro. Iyo PDA-yakagadziridzwa nanoPE jira rinobva raputirwa neMXene mhinduro kugadzira MXene/ nanoPE machira. Iyo nzira iri nyore, inogoneka uye yakakodzera kugadzirira kukuru kweMXene/nanoPE machira.

Schematic dhizaini yekupisa kweganda remunhu rakafukidzwa nemachira echinyakare uye MXene / nanoPE machira uye maitiro ekugadzirira uye maitiro eMXene / nanoPE machira.

Machira eMXene/nanoPE haangove ane zvivakwa zvakanaka zvemukati zvePRH chete, asiwo anoratidza kudziya kwezuva (73.5 ℃) nekudziya kwejoule (55℃, 5V) nekuda kweMXene's low mid-infrared emissionability, high photothermal conversion performance uye magetsi conductivity. Uyezve, iwo matatu ekudziya modhi anogona kuchinjika nyore kana kusanganiswa, zvichiita kuti MXene/nanoPE machira anyatso kupisa muviri wemunhu zuva rese mumamiriro akasiyana.

Pamusoro pezvo, machira akawanikwa eMXene/nanoPE anoratidzawo akanakisa kupfekwa uye kupfeka anodzivirira zvimiro, anosanganisira simba remuchina, kupindira kwemhepo, kuramba kwemhepo, kudzoreredza moto, magetsi emagetsi kupindira kudzivirira, antibacterial zvivakwa, kukurumidza kuomesa zvivakwa, nezvimwe, zvichiita kuti ive yakakodzera zvinhu zvekukwikwidza. uye masisitimu eiyo chaiyo yekupisa manejimendi yemuviri wemunhu mune ramangwana.

Kuita kunopfekeka kweMXene/nanPE machira

Ti3C2Tx Mxene-yakashongedzwa Nanoporous Polyethylene yePassive uye Active Personal Precision Heating Yakabudiswa muACS Nano.
