A cikin 'yan shekarun nan, fasahar sawa ta haɓaka cikin sauri, kuma masu bincike sun ƙirƙiri nau'ikan na'urori masu iya aiki da yawa, wanda ya wadatar da rayuwar mutane sosai. Don kama makamashin injin da aka rarraba a kusa da na'urori masu sawa, fasahar girbin makamashi kamar gogayya nanogenerator (TENGs) an ci gaba. Duk da haka, Fina-finan polymer da aka saba amfani da su a cikin TENGs don tarin makamashi na ɗigon ruwa suna da asara kamar ƙarancin iska., rashin kyawun kusancin fata da kuma hydrophobicity mara kyau, wanda ke iyakance ƙarin aikace-aikacen su a cikin filin sawa. Saboda haka, ci gaban hana ruwa, numfashi, gyare-gyaren kai da sauran yadudduka masu aiki da yawa don gane tarin kuzarin motsin ɗan adam da ɗigon ruwa na muhalli makamashi yana da matukar mahimmanci ga dorewar samar da wutar lantarki na samfuran lantarki masu sawa.. Ganin haka, masu bincike a Cibiyar Nanoenergy da Systems ta Beijing, Kwalejin Kimiyya ta kasar Sin ta samar da TENG na masana'anta (Farashin F-TENG), wanda ba wai kawai yana da kyawawan halayen iska da kuma abubuwan warkarwa na hydrophobic ba, amma kuma yana nuna ingantaccen canjin makamashi.



Siffofin F - TENG


A surface abu na hydrophobic masana'anta ya hada da SiO2 nanoparticles, FDTS da PVDF-HFP. Ayyukan haɗin gwiwar waɗannan sassa uku suna sa masana'anta su nuna kyakkyawan hydrophobicity da acid da alkali juriya. In addition, pvDF-HFP na iya haɓaka ƙwayoyin FDTS don matsawa zuwa saman ƙarƙashin yanayin zafi saboda ƙarancin canjin gilashin sa., kuma gane aikin gyaran kai na hydrophobic. Gilashin hydrophobic yana tsaftace kansa kuma ana iya cire foda na graphite a sauƙaƙe daga saman ta ɗigon ruwa.. In addition,Bugu da kariken sun gwada tasirin iska na masana'anta mai rufi da kuma masana'anta na asali. Ƙarfin iska na yadudduka na hydrophobic ya fi girma fiye da na yau da kullum na kayan denim na kasuwanci. Wadannan sakamakon suna nuna cewa masana'anta na hydrophobic har yanzu suna da kyakkyawan yanayin iska da kwanciyar hankali a cikin aikace-aikacen sawa.



Shirye-shirye da kuma halayyar masana'anta na hydrophobic


Masu bincike sun gina F-TENG don samar da wutar lantarki ta hanyar amfani da yadudduka na hydrophobic multifunctional. Lokacin da ɗigon ruwa ya faɗo daga wuri mai tsayi, da farko yana fadowa a saman sannan kuma ya bazu a saman saman hydrophobic. Kafin digo ya zo cikin hulɗa da babban lantarki, za a rarraba duk cajin da aka jawo akan wutar lantarki ta ƙasa. Da zarar ɗigon diffus ɗin ya yi hulɗa tare da saman lantarki, Ana canjawa da electrons daga saman lantarki zuwa na'urar lantarki don daidaita bambancin yuwuwar, samar da sigina kololuwar halin yanzu. Lokacin da ɗigon yaɗuwar ya kai iyakar yankin su, sun fara kwangila da zamewa daga saman hydrophobic. Tun da ɗigon yaduwa yana raguwa yayin da ɗigon ruwa ke raguwa, wutar lantarki ta ƙasa ta sake jin kishiyar cajin don daidaita madaidaicin cajin akan saman hydrophobic kuma ya haifar da kishiyar kololuwar halin yanzu.. Sakamakon gwaji ya nuna cewa masana'anta na hydrophobic yana da kyakkyawan aikin fitarwa.



Tsarin aiki da ingantawa na F-TENG


Don nuna kyakkyawan aiki na F-TENG a cikin tarin makamashi na droplet ruwa, masu bincike sun gudanar da gwaje-gwajen gwaje-gwaje don kwatanta ainihin yanayi don gwada kayan lantarki na F-TENG. Matsakaicin ƙarfin fitarwa na F-TENG ya fi na al'adar al'ada guda-electrode yanayin TENG don tarin makamashin digo na ruwa., cimma jimlar canjin canjin makamashi na 2.9%. Bayan 18,000 hawan keke, F-TENG bai nuna wani gagarumin jujjuyawar wutar lantarki ba, yana nuna kwanciyar hankali na dogon lokaci a aikace-aikacen tattara makamashi na droplet. Ana amfani da F-teng don cajin capacitors na kasuwanci daban-daban. The 0.47 μF capacitor za a iya cajin zuwa 12 V in 40 s. Daga karshe, An yi amfani da F-TENG don haskaka LED, kuma aka gano cewa 25 Ana iya kunna ledoji ta digon ruwa guda ɗaya. Wannan yana nuna cewa F-TENG na iya yadda ya dace wajen tattara makamashin zubar ruwa da samar da tsaro ga na'urori masu sawa, wanda yana da babban damar aikace-aikace a nan gaba.
