Projekat

Razvoj opreme i procesa dobijanja polimernih kompozitnih materijala sa unapred definisanim funkcionalnim svojstvima (MPNTR - 34011)

Sažetak

Predmet ovog istraživanja je kvantitativna procena adhezije između fotopolimerizujućeg kompozitnog filma na bazi Bis-GMA (Bisfenol A glicidilmetakrilata)/TEGDMA (trietilen glikol dimetakrilata) kao matrice i čestica na bazi aluminijum oksida dopiranih gvožđem na metalnoj podlozi. Korišćene su dve različite metalne podloge, jedna od srebra (u daljem tekstu 'srebro') i jedna pozlaćena mesingana pločica sa međuprevlakom od nikla (u daljem tekstu 'zlato'). Adhezija je merena korišćenjem mikroindentacije i upoređena je sa izmerenim uglom kvašenja kompozita na datim podlogama. Pokazalo se da se podloge, iako sličnih mehaničkih svojstava koje se ogledaju u veoma bliskim vrednostima tvrdoće, razlikuju po ostvarenoj adhezivnoj vezi sa polimernim fotopolimerizujućim filmom. Dodatak keramičkih čestica u polimernu matricu dodatno je povećao adheziju kompozitnog filma na obe podloge, dok je trend adhezije u zavisnosti od tipa podloge održan.
