Termokromni polimeri in vpliv 3D tiska termokromne polilaktične kisline na mehanske lastnosti izdelka : zaključna naloga Razvojno raziskovalnega programa I. stopnje StrojništvoKlemenc, AnžeTermokromizem je reverzibilen pojav, ki pri segrevanju ali ohlajanju temelji na spremembi barve snovi. Termokromno barvilo je dodano polimerom, ki se lahko pojavljajo kot termoplasti, elastomeri ali ... v obliki premazov. S svojo barvno spremembo se lahko termokromni materiali uporabljajo kot pokazatelji temperaturnih razlik pri skladiščenju nevarnih snovi, pakiranju živil, kot senzorji mehanskih obremenitev, regulatorji prepustnosti svetlobe in še v mnoge druge namene. Zaključna naloga obsega proučevanje vpliva 3D tiskanja termokromnega polimera PLA na njegove mehanske lastnosti. Proučevali smo vpliv temperature tiskanja na hitrost spremembe termokromne reakcije, vpliv UV svetlobe na termokromno reakcijo v 3D tiskanem polimeru, vpliv nateznega obremenjevanja materiala na spremembo barve polimera, vpliv temperature na viskoznost termokromnega polimera PLA ter termične lastnosti termokromnega PLA (DSC meritve). Ugotovili smo, da temperatura tiska vpliva na mehanske lastnosti polimera, da UV svetloba uniči termokromni mehanizem v polimeru, ter da se viskoznost polimera s poviševanjem temperature znižuje. Določili smo točko steklastega prehoda, temperaturo kristalizacije ter točko taljenja komercialnega termokromnega polimera.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [A.
