Fasahar daidaita shafi ta Nanoscale, a matsayin fasaha ta zamani, tana taka muhimmiyar rawa wajen ingantaaikin zaruruwan gilashiNanomaterials, saboda babban yankin saman su, ƙarfin aikin saman su, da kuma kyawawan halayen sinadarai na jiki, na iya inganta daidaito tsakanin wakilin girma da saman zaren gilashi, ta haka ne za su ƙara ƙarfin haɗin su. Ta hanyar shafa wakilan girma na nanoscale, ana iya samar da shafi mai daidaito da kwanciyar hankali na nanoscale akan saman zaren gilashi, yana ƙarfafa mannewa tsakanin zaren da matrix, don haka yana inganta halayen injiniya na kayan haɗin. A aikace-aikace, ana amfani da matakai na ci gaba kamar hanyar sol-gel, hanyar fesawa, da hanyar nutsewa don shafa wakilan girma na nanoscale don tabbatar da daidaito da mannewar murfin. Misali, ta amfani da wakilin girma wanda ke ɗauke da nano-silane ko nano-titanium, da kuma shafa shi daidai gwargwado a saman zaren gilashi ta amfani da hanyar sol-gel, ana samar da fim ɗin nanoscale SiO2 akan saman zaren gilashi, yana ƙara ƙarfin saman sa da kusancinsa sosai, kuma yana ƙara ƙarfin haɗin sa tare da matrix na resin.

Misali, magance saman zaren gilashi da tsarin plasma mai ƙarancin zafin jiki da haɗa shi da wakilin girman organosilicon na iya samar da shafi mai juriya ga UV da zafin jiki mai yawa, wanda ke tsawaita rayuwar kayan haɗin. Nazarin ya nuna cewa ƙarfin juriya na haɗaɗɗun zaren gilashi da aka shafa da hanyoyin taimakon plasma za a iya ƙaruwa da fiye da kashi 25%, kuma aikinsu na hana tsufa yana da matuƙar ingantawa a cikin yanayin zafi da danshi mai canzawa.

4. Bincike kan Tsarin Tsarawa da Shirye-shiryen Rufin Wakilai Masu Sauƙin Girma

Rufin wakili mai amsawa mai wayo su ne rufin da zai iya mayar da martani ga canje-canje a cikin muhallin waje, kuma ana amfani da su sosai a cikin kayan fasaha, na'urori masu auna firikwensin, da kayan haɗin gwiwa masu warkarwa. Ta hanyar ƙirƙirar wakilai masu auna firikwensin muhalli ga yanayin zafi, danshi, pH, da sauransu, zaruruwan gilashi na iya daidaita halayen saman su ta atomatik a ƙarƙashin yanayi daban-daban, ta haka ne za su cimma ayyuka masu wayo. Yawancin lokaci ana samun wakilai masu auna firikwensin ta hanyar gabatar da polymers ko ƙwayoyin halitta tare da takamaiman ayyuka, wanda ke ba su damar canza halayensu na physicochemical a ƙarƙashin abubuwan da ke motsa jiki na waje, don haka cimma tasirin daidaitawa. Misali, amfani da rufin wakili mai auna firikwensin da ke ɗauke da polymers masu saurin amsawa ga yanayin zafi ko polymers masu saurin amsawa ga pH kamar poly (N-isopropylacrylamide) na iya haifar da canje-canje a cikin yanayin zafi ko yanayin acidic da alkaline, yana daidaita kuzarin saman su da danshi. Waɗannan rufin suna ba da damar zaruruwan gilashi su kula da mannewa da dorewa mafi kyau a cikin yanayi daban-daban na aiki [27]. Nazarin ya nuna cewahaɗakar fiber na gilashiAmfani da shara mai wayo yana kiyaye ƙarfin juriya mai ƙarfi a ƙarƙashin canjin yanayin zafi kuma yana nuna juriya mai kyau ga lalata a cikin yanayin acidic da alkaline.
