Nā te pakarutanga o te COVID-19 kua nui ake te aro ki te tiaki whaiaro. He taputapu nui ngā rauemi tātari muka (pēnei i ngā kopare hauora, ngā tātari hauhautanga, me ētahi atu) mō te tiaki i ia rā, ā, ka taea te aukati i ngā poke o te hau. Heoi, he nui ake te ahua o te rauemi tātari hau muka o nāianei, he iti ake te pai o te tātari, he iti ake te whānui o te muka, ā, nā te nui o te kōhao, he uaua ki te whakatutuki i te tono mahi a ngā huaketo i roto i te rauemi iti pēnei i te hopu, ā, i te nuinga o te wā kāore i te whakamahia tēnei rauemi hei patu i ngā huaketo, ka tipu haere tonu te hopu i ngā moroiti, ka ngāwari te mate tuarua kino atu. Nō reira, he mea nui kia whakawhanakehia ngā rauemi tātari muka-nano me ngā mahi patu huakita me te patu huaketo.

SCY mō ngā kopare kanohi

Nō nā tata nei, i kōrerohia e tētahi rōpū rangahau nanofiber i arahina e Ahorangi Jianyong Yu me Ahorangi Bin Ding o Te Whare Wānanga o Donghua tētahi hanganga kupenga tino ngāwari o te nanofiber aerogel. Mā te silane sol/SiO2 nano fiber/halide amine modifier i whakaurua atu ki roto i te marara o ngā nanofiber cellulose huakita (BC), i muri i te whakamaroketanga tio, ka hangaia e te muka BC i roto i te SiO2 he anga whatunga pai tuarua, e hanga ana i te hanganga muka, he tino kaha te tono i roto i te mara o te rauemi tātari hau antibacterial.

Te tukanga whakarite me te mahi o te hanganga whare herehere nanofiber aerogel

I rangahauhia e ngā kairangahau te whai huatanga tātari me te ātete piezo o ngā aerogels me ngā ihirangi nanofiber BC rerekē i runga i te PM0.3. I te pikinga ake o te ihirangi BC, ka piki haere te mahi tātari me te ātete piezo o ngā aerogels. Ina 20wt% te ihirangi muka BC, ka taea e te whai huatanga tātari o te aerogels te eke ki te 99.97%, ā, ko te ātete piezo he 189Pa. Mā te hanga anō i ngā tauira hanganga toru-ahu o te aerogels muka SiO2 me te aerogels muka nano me te hanganga whare herehere, te whakatakoto i ngā tawhā hau me te rahi matūriki o ngā matūriki tātari, ka taea te whiwhi i te tohatoha o te ātete hau me te hopu i ngā matūriki totoka e ngā rauemi. Ki te whakatauritea ki te aerogels muka SiO2, ka taea e te aerogels whare herehere kupenga te hopu i te nuinga o ngā matūriki, ā, ka taea e te whatunga tuarua BC i roto i te aerogels te hopu pai i ngā matūriki iti. Hei tāpiri, ka taea te aromatawai i te ātete mā te tae o te mara ātete hau.

Te mahi tātari hau me te whakatauira o ngā aerogel

I roto i te tukanga tono mahi, whai muri i te hau poke mā te whakakōroi i te aerogel, ka taea e te hanganga mata muka nano te aukati i ngā poke, inā koa ko te whatunga pai BC ka taea te aukati i ngā huakita, ngā huaketo me ngā matūriki iti, ka tukuna e te halide amine i runga i ngā pae mahi antimicrobial o te mata muka ngā katote chlorine hei whakamate katoa i te aukati i ngā moroiti, kia kore ai e pangia te parahanga tuarua. I taua wā anō, ka pau hoki te chlorine i tukuna e te here N -- Cl o te aerogel ka huri hei here N -- H. Ina whakakōroitia anō te aerogel, ka taea te whakakōroitia anō te here N -- H i runga i te whatunga muka ki te here N -- Cl, ka tutuki ai te huringa whakaora o ngā āhuatanga patu huakita me te patu huaketo. Ko te whakarite i te rauemi e whakarato ana i tētahi whakaaro hou mō te whakawhanake i tētahi whakatupuranga hou o ngā rauemi tātari hau antibacterial me te antiviral.

Te tukanga whakarite me te mahi o te hanganga whare herehere nanofiber aerogel

Mā te whakamahi i ngā Aerogel nano ngāwari rawa atu i hangaia e te Tunneling Nanonets me te hoahoa rite ki te Kete Hierarchical ka taea te whakamahi i te kaupapa "Renewable Antimicrobial Air Filtration" i whakaputaina ki roto i te Advanced Functional Materials.

To tatou hua DTY 70D/24F/2SCY 7070/24, SPANDEX 70DPANEKEKI 140D ka taea te whakamahi hei hanga taura mō ngā kopare.
