Ulusi wa kaboni uli ndi mawonekedwe amphamvu kwambiri komanso kulemera kopepuka, ndipo zinthu zophatikizika ndi polima ndizoyenera kwambiri zakuthambo, mafakitale amagalimoto, masamba a turbine yamphepo ndi zinthu zamasewera.Komabe, zinthu zophatikizika zoterozo zidzalephera mowopsa popanda chenjezo, mofanana ndi kugwa kwa zoumba.

Posachedwapa, ofufuza ochokera ku Oak Ridge National Laboratory ndi Virginia Tech ndi State University adapanga njira ndikuyifalitsa mu Journal of Composites Science and Technology.Pongowonjezera nano-TiO2, ikhoza kupereka chenjezo loyambirira la kutaya mphamvu.

Zida zophatikizika ndi kaboni fiber, makamaka zida zophatikizika zochokera ku epoxy resin, zimakhala zosavuta kutha pamene mgwirizano pakati pa ulusi ndi matrix walephera.Ngati palibe zizindikiro zochenjeza zakunja, zothyoka mwadzidzidzi zimatha, zomwe zimalepheretsa kugwiritsidwa ntchito kwa zida zophatikizika izi pamapangidwe ake.Anthu akuyang'ana njira zosiyanasiyana zowunikira kukhulupirika kwamafuta a carbon fiber composites, monga kuyika zida za piezoresistive muzinthu, zomwe zimasintha kukana ndi kupsinjika.Zida za piezoresistive zimatha kusintha zovuta zamakina kukhala ma siginecha amagetsi, omwe amatha kuzindikirika ndi masensa kuti azitha kuyang'anira thanzi lazinthu zophatikizika.

Ofufuza adayika TiO2Nano titanium dioxidema nanoparticles mu zokutira polima kapena kukula kwa ulusi wa kaboni kuti zinthu za piezoresistive zigawidwe mofanana muzinthu zophatikizika.Sizing nthawi zambiri imagwiritsidwa ntchito popanga kaboni fiber, kuti ikhale yosavuta kukonza ndikugwiritsa ntchito ndikuphatikiza ndi masanjidwewo, ndipo pamapeto pake imakhazikitsa luso lozindikira zovuta pochita izi.Kupanikizika kumachotsedwa, kukana ndi zero, ndipo pamene kupanikizika kumapangidwa, kukana kumawonjezeka.Kumene, kuchuluka kwa TiO2 nanoparticles anawonjezera ayenera lizilamuliridwa, mkulu kwambiri gawo kuchepetsa mphamvu ya gulu zakuthupi, ndi Kuwonjezera bwino kumapangitsanso damping ntchito (mantha mayamwidwe ndi buffering ntchito) za nkhaniyo.

Hongwu kampani kupereka Nano titaniyamu woipa motere:

1. Anatase TiO2, kukula 10nm, 30-50nm.99% +

2. Rutile TIO2, kukula 10nm, 30-50nm, 100-200nm.99% +

Chonde khalani omasuka kutifunsa mafunso aliwonse.
