Masayendisiti akagadzira epurasitiki akaenzana nesimbi - akasimba asi asina kuremerwa. Synthesis.Zvinoita, izvo zvinoitika pamhepo tembiricha, zvinoda chete zvakachipa zvekushongedza, uye polymer inogona kuve yakagadzirwa mumashiti akakura ari eNanometers akakosha.
Zvinyorwa zviri mubvunzo zvinonzi polyamide, network yakarongedzwa yemidhodhi mapoka emakemikari akasungirirwa mapoka ekomboni. Hydrogen zvisungo padanho rese remaketani avo, izvo zvinowedzera simba rakawanda rezvinyorwa.
"Ivo vanonamatira pamwe chete seVelcro," akadaro mutungamiri munyori Michael Streno, a Mit Chemical Engineri Nyowani, asi zvakare kukunda hofori intermolecular hydrogen zvisungo zvinonyadzisa polymer yese.
Uye zvakare, iyo polymers itsva inogona kuumba zvisizvo zvinogadzirisa.
"Unogona kuunganidza pabepa here? Zvinoshingairira, kazhinji kazhinji, haugone kuzviita kusvikira pabasa redu," Srong. "Saka, takawana muchina mutsva." Mubasa iri razvino, timu yake yakakunda dambudziko rekuita kuti awirirane-maviri-maviri awirirane.
Chikonzero chePolyaramides vane chirongwa chekuronga ndechekuti Polymer Synthesis zvinosanganisira maitiro anonzi Authocate Wafers kugadzira inch-wide laminates isingasviki 4 nanometers gobvu. iyo ingangoita imwe chete-milorion yepepa rehofisi.
Kuti udzikise manhamba emuchina wezvemanyorero, vaongorori vakayera simba rinodiwa kuti vaite padzimba renyama. Chinhu icho chinogona kushandiswa sekudzivirira kwesimbi panzvimbo yematare, senge midzi yemotokari, kana sedhizaini yekupedzisira yekuita kuti isimbe nhumbu huru, yakakwana yekupa madiki
Mune ramangwana, tarisiro inotarisira kunzira yePolymeration kune dzakasiyana polymeri kupfuura iyi kevlar analog. "Polymers akatikomberedza," akadaro. "Vanoita zvese." FUNGIDZIRA uchiendesa marudzi mazhinji ePolymers, anotodza magetsi anogona kuitisa magetsi.
Munyika yakakomberedzwa nepurasitiki, nzanga ine chikonzero chekufara nezveimwe polymer ine chekuita neyekudya, izvi zvakarongeka. Purasitiki.
