Impela uma ungumthandi wokuqina noma uma uthanda nje ezemidlalo futhi ujwayele ukuzivocavoca njalo, impela kwesinye isikhathi uke wezwa ngento efana nokuthi keratin njengoba kuvame ukusetshenziswa emikhiqizweni yezempilo neye-cosmetology. Ngakolunye uhlangothi, ukuthi isetshenziselwa lolu hlobo lomkhiqizo akusho ukuthi ayinikezi ezinye izinhlobo zezinsiza, esimweni esithile se-keratin, ibuye isetshenziselwe ukuqeda ukungcola okukhona emanzini noma ukuthuthukiswa kwezinto ze-polymeric.
Ngalokhu engqondweni, namhlanje ngifuna sikhulume ngocwaningo lwakamuva olwenziwe ngabaphenyi boMnyango Wezinto Ezithuthukisiwe kanye neNanotechnology ye I-Instituto Tecnológico de Querétaro ngokuqondiswa ngokuhlanganyela ngochwepheshe u-Ana Laura Martínez Hernández noCarlos Velasco Santos, lapho bephenya khona izakhiwo ezinikezwa ukufakwa kwe-keratin ezintweni ezihlukile zokwenziwa ezifana ne-polymethylmethacrylate, i-polypropylene, i-polyurethanes ...
Ukusetshenziswa kwe-keratin ekwenziweni kwentambo yokuphrinta kwe-3D kungaletha izinzuzo eziningi
Njengoba omunye wabakhulumeli beqembu locwaningo echaza:
Sisebenzise le keratin kuzinhlelo zokusebenza ezinjengokukhiqizwa kokuhlanganiswa okwenziwe nge-polymer. Ihambisana kakhulu ne-polymer yokwenziwa ngenxa yemvelo yayo ye-hydrophobic, okungukuthi, ukuxosha amanzi. Lokhu kusiza ukuhlakazeka kwemicu kanye no-matrices. Sakha futhi izinhlanganisela ezicutshungulwa ukuphrinta kwe-3D nge-polylactic acid matrix nokuqiniswa kwezinto zekeratin nezinguquko ezihambisanayo kuzakhiwo ze-thermomechanical kanye ne-conductivity ye-thermal.
Esikufunayo ukuqinisa okokusebenza kwemvelo, okufana nesitashi samazambane kanye ne-crustacean chitosan ngale keratin. Siqale sabasebenzela elabhorethri kwase kuba sezingeni lezimboni, sisebenzisa i-extrusion ukuqhathanisa izakhiwo ezikhuphuke ngamaphesenti afinyelela ezinkulungwaneni ezimbili. Ku-post-doctorate ngisebenzisa i-polylactic acid (i-PLA) ne-keratin ekuphrinteni kwe-3D kepha manje ngezinwele zonogwaja.
Siphinde sifunde ukuba usizo kwayo ekuhlanzweni kwamanzi angcolile; Ngalo mqondo, i-keratin inamaqembu asebenzayo atholakala kuma-amino acid, yizindawo lapho kungcoliswa khona ukungcola okuhlukahlukene okunjengezinsimbi ezisindayo, kufaka phakathi i-hexavalent chromium (Cr), lead (Pb), nickel (Ni) namanye ama-hydrocarbon.
Izinsimbi zekhabhoni ezinhlotsheni zazo ezine-oxidized nezingahluziwe, futhi zenziwe zasebenza namanye amaqembu amakhemikhali namaketanga amakhulu zisetshenzisiwe ekwakhiweni kwezinhlanganisela, ama-nanocomposites, ama-multiscale kanye nama-multidimensional composites kuma-matrices we-polymeric lapho kusetshenziswe khona ama-polymers afana ne-epoxies. -starch ne-polylactic acid, icutshungulwe futhi yahlanganiswa ngezindlela ezahlukahlukene ezisukela ekubunjweni, umjovo, i-extrusion, ukuphrinta kwe-3D, i-electrospinning nokwelapha i-situ, inezinto ezishisayo, ezikagesi nezomshini, kuya nge-matrix esetshenzisiwe.
