Nekukurumidza kuvandudzwa kwezvishandiso zvinopfekwa zvinopfekwa, ganda remagetsi rinova chinhu chakakosha chekubatana kwevanhu-kombuta, uye kuchengetedzwa kwayo kunova kwakakosha. Kushandisa zvakasikwa sirika mapuroteni uye karusiyamu ions sezvo mbishi zvinhu, chikwata kubva Shanghai University of Science uye Technology akaita läpinäkyvä, stretchable, kuzvirapa uye yakachengeteka zvikuru conductive zvemagetsi ganda zvinhu zvakanaka murazvo retardant zvinhu. Chikwata chekutsvagisa chakaongorora zvakadzama magadzirirwo ayo ekudzoreredza moto uye yakagadzira yekutanga yambiro sisitimu inogona kufambisa ruzivo kuburikidza nemasaini masaini pasi pemamiriro akanyanya, ichipa pfungwa nyowani yekuenderera mberi nekugadzira ganda idzva reionic nekuvandudza kuchengetedzwa kwemidziyo inopfeka.

Kugadzirira uye kuratidzwa kweSFCIS

Nzira mbiri dzakasiyana dzakashandiswa kugadzirira fibroin calcium ion electronic skin (SFCIS) kuti isangane nezvinodiwa zvemashandisirwo akasiyana siyana. SFCIS ine kujeka kwakanyanya. Iyo mechanical properties yeSFCIS mumhoteredzo inogona kudzorwa nekugadzirisa zviri mukati me calcium ions, kuitira kuti modulus yeSFCIS ifanane neye biological tissues uye kushanda kwayo kwekushanda kwakasimba. Zvichakadaro, SFCIS ine yakanaka kutambanudza (elongation rate kusvika ku1200%) uye magetsi conductivity (1.96ms ·cm-1), iyo inogona kusangana nezvinodiwa zvezvishandiso zvinopfekwa. Munzvimbo yemhute yemvura, SFCIS zvakare ine yakanaka yekuzviporesa kuita.

Mechanical zvimiro zveSFCIS

Iko kuiswa kwe calcium ions kunogona kuchinjana zvinhu nemamiriro ekunze uye kuchengetedza kugadzikana kwemvura yakasanganiswa muzvigadzirwa. Kune rumwe rutivi, kuvapo kwemvura yakasungirirwa kunopa nhamba huru yehydrogen zvisungo zvemagetsi eganda zvinhu, izvo zvinoita kuti ive nepamusoro kuoma uye kukwanisa kuzviporesa. Nekune rumwe rutivi, kana zvinhu zvacho zvave pachena kune nharaunda inopisa, calcium chelating mvura inogona kuita kuti zvinhu zvitore kupisa uye kunyunguduka panguva yekutanga kusangana nemurazvo, uye kuwedzera nekukurumidza, kugadzira dziviriro yemukati yepasi. Saka rudzi urwu rwemagetsi ganda zvinhu zvine yakanaka murazvo retardant pfuma.

Flame retardant mechanism yeSFCIS uye SEM dhayagiramu yekupisa pamusoro

Chikwata chakashandisa thermo-mass spectrometry (TGA-MS) kunyatsoongorora shanduko yechinhu chimwe nechimwe mumatanho akasiyana ekuita kupisa, uye nekudaro vakafungidzira kuti kudzoreredza moto kunosanganisira kupera mvura, carbonization layer kuwedzera, multilayer shielding uye mahara radical kudzimwa. Mukuyedza kudzikamisa okisijeni index bvunzo, SFCIS inoratidza kuita kwemoto kudzoreredza kufananidzwa neinjiniya mapurasitiki, uye hapazove nekutonga, kudonhedza uye dzimwe njodzi dzechipiri mukuyedza kupisa, izvo zvinovimbisa zvakanyanya kuchengetedzwa kwezvinhu munzvimbo yemoto. .

Mukuita, timu yakagadzirawo yambiro isina waya yemoto yakavakirwa pakuchinja kweSFCIS magetsi conductivity nedhigirii rekupisa.

Kazhinji, boka racho rinobva pane zvakasikwa silk protein, iyo nzira yekushandisa yakagadziriswa yakagadziriswa ine yakanaka magetsi conductivity, mechanical properties, self-healing properties uye flame retardancy yeion conductor electronic skin material, rudzi urwu rwezvinhu zvekutsvakurudza kupisa nzira inopa a feasible scheme, zvakare serudzi rutsva rwekugadzira ganda rekugadzira rinopa chitima chitsva chekufunga, kuvandudza chinopfekeka chekuchengetedza michina ine kujekeswa kwakakosha.
