Pali matekinoloje atsopano ambiri m'makampani opanga zida, koma ochepa omwe ali ndi mafakitale.Kafukufuku wa sayansi amafufuza vuto la "kuchokera ku ziro mpaka kumodzi", ndipo zomwe makampani akuyenera kuchita ndikusandutsa zotsatira kukhala zinthu zopangidwa mochuluka ndi khalidwe lokhazikika.Hongwu Nano tsopano ikukulitsa zotsatira za kafukufuku wasayansi.Nano siliva mndandanda zida monga nanowires siliva ndi zinthu kutsogolera Hongwu Nano.M'zaka zaposachedwa, Pakhala kupita patsogolo ndi chitukuko pazambiri zonse zamsika, ukadaulo wopanga, mtundu ndi zotuluka, ndi zina zambiri, ndipo ziyembekezo zake ndizabwino kwambiri.M'munsimu muli chidziwitso cha mawaya a nano siliva kuti muwerenge.
1. Kufotokozera kwazinthu
Silver nanowirendi mawonekedwe amtundu umodzi wokhala ndi malire opingasa a 100 nanometers kapena kuchepera (palibe malire munjira yolunjika).The nanowires siliva (AgNWs) akhoza kusungidwa mu zosungunulira zosiyanasiyana monga deionized madzi, Mowa, isopropanol, etc.
2. Kukonzekera kwa mawaya a nano Ag
Njira zokonzekera mawaya a Ag nano makamaka zimaphatikizapo mankhwala onyowa, polyol, hydrothermal, njira ya template, njira ya kristalo ya mbewu ndi zina zotero.Njira iliyonse ili ndi ubwino ndi kuipa kwake.Komabe, mawonekedwe opangidwa a Ag nanowires ali ndi ubale wokulirapo ndi momwe kutentha kumachitikira, nthawi yochitira, komanso ndende.
2.1.Mmene kutentha anachita: Ambiri, ndi apamwamba anachita kutentha, siliva nanowire adzakula wandiweyani, zimene liwiro adzachuluka, ndi particles adzachepa;pamene kutentha kumachepetsa pang'ono, m'mimba mwake idzakhala yaying'ono, ndipo nthawi yochitira idzakhala yotalikirapo.Nthawi zina zochita zimakhala zazitali.Kutsika kwa kutentha nthawi zina kumapangitsa kuti tinthu tichuluke.
2.2.Nthawi yochitira: Njira yoyambira ya nano silver wire synthesis ndi:
1) kaphatikizidwe wa makristasi a mbewu;
2) anachita kupanga ambiri particles;
3) kukula kwa nanowires siliva;
4) makulidwe kapena kuwonongeka kwa nanowires zasiliva.
Choncho, momwe mungapezere nthawi yabwino yoyimitsa ndi yofunika kwambiri.Nthawi zambiri, ngati zomwe zayimitsidwa kale, waya wa siliva wa nano umakhala wocheperako, koma umakhala wamfupi komanso uli ndi tinthu tambiri.Ngati nthawi yoyimitsa ikadutsa, nanowire yasiliva idzakhala yayitali, njere imakhala yochepa, ndipo nthawi zina imakhala yokulirapo.
2.3.Kuyikira Kwambiri: Kuchuluka kwa siliva ndi zowonjezera pakupanga siliva nanowire synthesis kumakhudza kwambiri kapangidwe kake.Nthawi zambiri, pamene siliva zili pamwamba, kaphatikizidwe wa Ag nanowire adzakhala wandiweyani, zili nano Ag waya adzachuluka ndi zili particles siliva adzawonjezeka, ndipo zimene zidzafulumira.Pamene kuchuluka kwa siliva kumachepa, kaphatikizidwe ka waya wa nano wa siliva umakhala wocheperako, ndipo zomwe zimachitika zimakhala pang'onopang'ono.
3. Kufotokozera kwakukulu kwa Hongwu Nano's Silver Nanowires:
Diameter: <30nm, <50nm, <100nm
Utali: > 20um
Chiyero: 99.9%
4. Minda yogwiritsira ntchito ma nanowires asiliva:
4.1.Minda yoyendetsera: maelekitirodi owonekera, ma cell a solar amafilimu opyapyala, zida zovala zanzeru, ndi zina zambiri;ndi madulidwe abwino, otsika kukana kusintha mlingo pamene kupinda.
4.2.Ma biomedicine ndi antibacterial minda: zida zosabala, zida zojambulira zamankhwala, nsalu zogwirira ntchito, mankhwala ophera tizilombo, ma biosensors, ndi zina zambiri;antibacterial wamphamvu, wopanda poizoni.
4.3.Makampani a Catalysis: Ndi malo akuluakulu enieni komanso zochitika zapamwamba, ndizothandizira kuti pakhale zochitika zambiri za mankhwala.
Kutengera kafukufuku wamphamvu ndi mphamvu yachitukuko, tsopano inki zamadzi za nanowires zasiliva zitha kusinthidwanso.Magawo, monga mafotokozedwe a Ag nanowires, mamasukidwe akayendedwe, amatha kusintha.Inki ya AgNWs imakutidwa mosavuta ndipo imakhala yomatira bwino komanso kukana kochepera.
