Abstract
U ovom istraživanju pripravljeni su kompozitni materijali na temelju hidroksiapatita (HA) i kopolimera Boltorn H40/polikaprolakton(BH40/PCL). Hidrotermalnom pretvorbom aragonita iz sipine kosti sintetiziran je visokoporozni HA s potpuno očuvanom mikrostrukturom sipine kosti. Uranjanjem HA komadnih uzoraka u otopinu kopolimera BH40/PCL dobiven je kompozit hidroksiapatit/BoltornH40/polikaprolakton (HA/BH40/PCL). Kvalitativnom XRD analizom kompozitnih uzoraka dokazano je nastajanje HA te prisustvo kopolimera BH40/PCL u kompozitu. Rezultati dobiveni DRIFT metodom prikazuju vibracije veza karakteristične za HA i kopolimer u kompozitnom materijalu. SEM analiza uzoraka prikazuje očuvanu lamelarnu i poroznu strukturu sipine kosti na kojoj se nakon impregnacije kopolimer kapljičasto raspodjeljuje po površini hidroksiapatita. In vitro ispitivanja provedena u HBSS otopini tijekom 21 dan ukazuju na mineralizaciju kalcijevih fosfata na površini kompozitnog materijala. TGA metodom određeno je da kompozitni uzorci sadrže oko 37,7 mas.% kopolimera BH40/PCL.
Abstract (english)
Composite materials of hydroxyapatite (HA) and copolymer Boltorn H40/Polycaprolactone (BH40/PCL) were prepared. The hydroxyapatite was synthesized by the hydrothermal conversion of aragonite from the cuttlebone while completely preserving the original microstructure of the bone. The composite material hydroxyapatite/Boltorn H40/Polycaprolactone (HA/BH40/PCL) was prepared by immersing the HA in the solution of the copolymer. XRD analysis of the composite showed the diffraction peaks belonging to HA and BH40/PCL copolymer. The results obtained by the DRIFT method show the presence of the bands characteristic for the HA as well as for the copolymer in the composite material.SEM analysis of the composites shows the preserved lamellar and porous structure of the cuttlebone after impregnation and the presence of the copolymer clusters (drop shape) on the surface of HA. In vitro mineralization of calcium phosphate was observed on the composite material after 21 days of soaking in HBSS. TGA analysis showed that the composite material contains 37.7 wt.% of the BH40/PCL copolymer.
