Ososayensi baye basungula polymer ukuthi ungasusa okwesikhashana imibimbi

Abacwaningi eMIT baye basungula yini ebalulekile eyaba isikhumba wesibili. Kuyinto soft, zivumelanise nezimo futhi ube cishe ezingabonakali. Okwamanje, iqembu lososayensi ukutadisha ukusetshenziswa okuhle impahla yezimonyo, okungase ukususa ngempumelelo imibimbi, izikhwama phambi kwamehlo ukwelapha nethonya ekuvuseleleni phezu ukubukeka kwayo yonke indawo umuntu. Lokhu kwaziswa Isinyathelo esilandelayo siwukushumayela ukwelapha izifo zesikhumba, izidakamizwa esasikhipha, noma umane umswakama, - ngakho uthi ucwaningo co-umbhali Daniel Anderson, uProfesa Hlobanisa woMnyango Chemical Engineering, esitatimendeni. Okutholakele ashicilelwe ephephabhukwini "Imvelo Materials".

Kuyini "luyisikhumba sesibili"?

Wadala ososayensi ebonakala- polymer abicah okuyinto ulingisa isikhumba enempilo. It has zonke izakhiwo mechanical kuyaqina yesikhumba abasha, kuyilapho futhi esiwuhogelayo kanye amanzi. enamathela imperceptible uyayiqeda imibimbi futhi ukunika ukubukeka ukubukeka bobusha - konke ngaphandle ukuhlinzwa koda namathuluzi ungavele ikhasi off ekupheleni kosuku zokusebenza.

Lesi sendlalelo ongabonakali inikeza mngcele nothango kuqinisekisa ngcono yezimonyo. Izindawo ezingaba, ke uyakwazi ukukhulula izidakamizwa endaweni kulezo zindawo ezidinga ukwelashwa. Lokhu kwenza kube ekahle ukusetshenziswa kubantu.

Isebenza kanjani?

Umkhiqizo usebenza ngezigaba ezimbili. Okokuqala, umuntu osebenzisa ukhilimu kungekho nto enemibala emihle, equkethe i-polymer elisuselwa siloxane. Lakhiwa neketanga kushintshana Silicon kanye zomoya-mpilo. Khona-ke, ukusebenzisa yesibili ukhilimu umbala omhlophe, okuyinto kulethe-platinum. Owenza usebenze resin ukwakha crosslinks futhi iba izacile, nokunwebeka kanye uhlakaza imisebe yelanga, esihlinzeka ukubukeka bobusha xaxa. Umthelela isicelo esisodwa kokubili okhilimu ekuseni kufanele usuku lonke, ngisho lapho zihlatshwa emisebeni ultraviolet nemvula.

nobunzima ucwaningo

Njengoba bekhula, isikhumba ilahlekelwa ukuqina yayo futhi kuyaqina, futhi lokhu ingenye izizathu zokuthi kungani waba kokuqala ukubheka amadala. Ukuthuthukiswa entsha kuhloswe ukubuyiselwa lezi izakhiwo. Dala okuqukethwe liziphatha ngendlela efanayo njengoba isikhumba, kunzima ngokwanele, - uthi ucwaningo co-umbhali. Abaningi baye bazama ukukwenza lokhu, kodwa izinto abakuthola okukhiphayo, kwakungafanele nezimo futhi kulula ukuyisebenzisa, futhi isikhumba ucasukile. Lezi idatha zokuhlola ayikwazanga ukufanisa ukunyakaza kwesikhumba futhi abakwazanga uyibuyisele ifomu yayo yasekuqaleni.

A impumelelo owenza abacwaningi Namanje kungagcini ngezinhloso ayeyisimonyo kuphela. I polymer entsha ihlolwe ngempumelelo amavolontiya womuntu. Nokho, ososayensi bafuna ukumthola inombolo zezinye izinhlelo zokusebenza, isibonelo, ukuphathwa eczema, amavukuzi ukususwa, kanye nokuphatha basekhaya izidakamizwa nemithi elwa namagciwane.
