Cercet\u0103tori de la Universitatea \u0219i Centrul de Cercetare Wageningen, \u021a\u0103rile de Jos, au dezvoltat un nou material care r\u0103stoarn\u0103 o presupunere de baz\u0103 din \u0219tiin\u021ba materialelor, scrie InterestingEngineering<\/a><\/span>.<\/p>\n

Substan\u021ba, numit\u0103 compleximer, combin\u0103 rezisten\u021ba plasticului cu u\u0219urin\u021ba de modelare a sticlei.<\/p>\n

Hibridul de culoarea chihlimbarului rezist\u0103 la impact asemenea plasticului, dar se tope\u0219te lent \u0219i este u\u0219or de prelucrat.<\/p>\n

P\u00e2n\u0103 acum, aceste propriet\u0103\u021bi erau considerate incompatibile.<\/p>\n

Spargerea regulii fragilit\u0103\u021bii<\/h2>\n

Timp de decenii, oamenii de \u0219tiin\u021b\u0103 au crezut c\u0103 materialele u\u0219or de remodelat sunt inevitabil fragile.<\/p>\n

Conform acestei teorii, materialele \u201esticloase\u201d, cu topire lent\u0103, ar trebui s\u0103 se sparg\u0103 la impact.<\/p>\n

Echipa din Wageningen a demonstrat contrariul.<\/p>\n

Compleximerul poate fi fr\u0103m\u00e2ntat, suflat \u0219i remodelat, dar rezist\u0103 la c\u0103deri f\u0103r\u0103 s\u0103 se sparg\u0103.<\/p>\n

Coordonatorul studiului, profesorul Jasper van der Gucht, spune c\u0103 descoperirea contrazice direct modelele clasice din fizic\u0103.<\/p>\n

Rezultatele arat\u0103 c\u0103 materialele asem\u0103n\u0103toare sticlei pot fi u\u0219or de prelucrat f\u0103r\u0103 a pierde din rezisten\u021b\u0103.<\/p>\n

\u201eMagne\u021bi\u201d moleculari \u00een locul leg\u0103turilor chimice<\/h2>\n

Descoperirea-cheie \u021bine de modul \u00een care materialul este men\u021binut la nivel molecular.<\/p>\n

Spre deosebire de materialele plastice clasice, compleximerii nu se bazeaz\u0103 pe leg\u0103turi chimice permanente.<\/p>\n

\u00cen schimb, materialul folose\u0219te atrac\u021bia fizic\u0103 dintre lan\u021buri polimerice \u00eenc\u0103rcate pozitiv \u0219i negativ.<\/p>\n

Aceste sarcini opuse ac\u021bioneaz\u0103 ca ni\u0219te magne\u021bi moleculari, men\u021bin\u00e2nd structura f\u0103r\u0103 leg\u0103turi rigide.<\/p>\n

Pentru c\u0103 aceste for\u021be ac\u021bioneaz\u0103 pe distan\u021be mai mari, lan\u021burile au mai mult\u0103 flexibilitate.<\/p>\n

Acest \u201espa\u021biu de respira\u021bie\u201d molecular permite absorb\u021bia \u0219ocurilor \u0219i o procesare facil\u0103.<\/p>\n

Cercet\u0103torii spun c\u0103 acest comportament a fost nea\u0219teptat.<\/p>\n

Descoperirea deschide noi direc\u021bii de design pentru polimerii avansa\u021bi.<\/p>\n

Materiale auto-reparabile \u0219i aplica\u021bii viitoare<\/h2>\n

Una dintre cele mai promi\u021b\u0103toare caracteristici este capacitatea de auto-reparare.<\/p>\n

Fisurile sau deterior\u0103rile pot fi remediate prin simpla \u00eenc\u0103lzire \u0219i presare a materialului.<\/p>\n

Materialul ar putea transforma produse precum panourile, mobilierul sau materialele de construc\u021bii.<\/p>\n

\u00cen viitor, repara\u021biile ar putea necesita doar o surs\u0103 obi\u0219nuit\u0103 de c\u0103ldur\u0103.<\/p>\n

Spre materiale plastice sustenabile<\/h2>\n

Versiunea actual\u0103 este ob\u021binut\u0103 din resurse fosile, dar se lucreaz\u0103 deja la alternative sustenabile.<\/p>\n

Oamenii de \u0219tiin\u021b\u0103 cred c\u0103 compleximerii ar putea deveni reciclabili, reparabili sau chiar biodegradabili.<\/p>\n

Scopul declarat nu este doar crearea unor materiale mai bune, ci \u0219i un viitor mai sustenabil pentru plastic.<\/p>\n","protected":false},"excerpt":{"rendered":"
