A al'ada, jiki ya rasa game da 50 kashi dari na zafinta ta hanyar haskaka hasken tsakiyar infrared. Don rage asarar infrared radiation, dabarar da ta dace ita ce daidaita yawan iskar infrared na yadi da tufafi, don gane m radiation dumama (PRH) na jikin mutum. Idan aka kwatanta da dabarun dumama na gargajiya, PRH yana da fa'idodin rashin amfani da makamashi, mafi daidaito da inganci. Duk da haka, Matsakaicin ikon rufewa na PRH yana iyakance a cikin muhallin waje, musamman a yanayin dare da rana da canjin yanayi sosai, yana da wuya a cimma daidaitaccen dumama jikin mutum. Saboda haka, ci gaban kayan aiki da tsarin da za su iya yin zafi daidai da jikin mutum a cikin hanyar da ta dace da makamashi, duk tsawon yini, yana da mahimmanci don rage matsalar makamashi da dumamar yanayi.




Domin magance wadannan matsalolin, Tawagar bincike ta jami'ar Zhengzhou ta ba da rahoton dabarun dumamar yanayi mai amfani da makamashi: Hanyoyin dumama guda uku, wato PRH ba tare da amfani da makamashi ba, makamashi ceton hasken rana dumama da diyya Joule dumama, an yi nasarar haɗa su cikin mayafin Mxene/nanoPE mai sawa (12 μm) tsarin ta shafi bakin ciki Ti3C2Tx Mxene shafi (1 &mm;m) akan polyethylene nanopore mai tsada (nanoPE) yadi.
A cikin tsarin shirye-shiryen, masu binciken sun fara yin polymerized Layer na polydopamine (PDA) a saman nanoPE masana'anta a wurin don samar da saman hydrophilic. PDA-gyara nanoPE masana'anta sannan kawai an lulluɓe shi da maganin MXene don samar da yadudduka na MXene/nanoPE. Hanyar yana da sauƙi, mai yuwuwa kuma ya dace da shirye-shiryen babban sikelin na MXene/nanoPE Textiles.



Tsarin tsari na canja wurin zafin fata na ɗan adam an rufe shi da yadudduka na gargajiya da MXene / nanoPE yadi da tsarin shirye-shirye da halayyar MXene / nanoPE yadi.

MXene/nanoPE Textiles ba kawai suna da kyawawan kaddarorin PRH na cikin gida ba, amma kuma yana nuna kyakkyawan dumama hasken rana (73.5℃) da joule dumama (55℃5V) iyawa godiya ga ƙarancin ƙarancin infrared na MXene, high photothermal hira yadda ya dace da lantarki watsin. Haka kuma, Hanyoyin dumama guda uku za'a iya canzawa cikin sauƙi ko haɗuwa, ba da damar MXene/nanoPE Textiles don daidaita jikin mutum daidai da rana a cikin yanayi iri-iri..
Bugu da kari, Abubuwan da aka samu na MXene/nanoPE suma suna nuna kyakkyawan sawa da sa kayan juriya, ciki har da ƙarfin injiniya, iska permeability, juriya na iska, harshen wuta, garkuwar katsalandan na lantarki, antibacterial Properties, sauri bushewa Properties, da dai sauransu., sanya su kayan takara masu dacewa da tsarin don daidaitaccen sarrafa zafin jiki na jikin ɗan adam a nan gaba.
