“…The presence of carbon peak became more apparent with the rise of GO reinforcement. Again, Tricalcium phosphate (TCP) and CaHPO4 structures, which can be formed due to heat treatment [10,12], were not found in porous structures. The sharp peaks formed by both HA and GO reinforced HA porous structures can be explained by the presence of crystallinity of these structures.…”

“…Furthermore, it is considered that the addition of GO with sp 2 hybrid bond structure increases the coefficient of expansion, thus tending to bind more to HA and increase cracks [12]. As a matter of fact, the increase in the amount of GO in the matrix material HA (especially over 1wt%) makes it possible to create cracks and negatively affect the mechanical properties due to the fact that the very strong carbon bonds form a tighter bond with the HA forms together with the heat treatment [10,21]. MPa in the 0.5wt% Gr nanoplates reinforced HA composite structure [23].…”

“…GO is an astonishing 2D material which shows astonishing mechanical resistance due to its sp 2 hybrid binding structure. GO is carbon based material; hence, it is non-toxic [9][10][11]. Gr and GO are also light, flexible, and biocompatible; therefore, it stands out as a promising material in the production of functional bioceramics used in biomedical applications [12].…”

Hydroxyapatite (HA) is a unique material that has the potential to be used to replace bones and teeth in the field of orthopedics and dentistry since HA exhibits quite similar biological and chemical characteristics to human bone. Hydroxyapatite ceramics are bioactive materials used to repair damaged human tissue. The pores in the porous hydroxyapatite ceramics provide a mechanical interlock, enabling a solid bond and fixation between the implant and bone. In this study, 0.5wt%, 1wt%, and 1.5wt% graphene oxide (GO) reinforced porous HA structures were obtained using the space-holder method to increase the strength of hydroxyapatite with low mechanical strength. NaCl was used as a spacer, and PEG 400 as a binder. Scaffold structures with 40% porosity rates were sintered at 1000 ᵒC under vacuum. Finally, a compression test was applied to the samples which were previously analyzed by SEM, EDS and XRD. The compressive strengths of 0.5%, 1%, and 1.5% graphene oxide reinforced porous HA samples were determined between 8.04 and 31.14 MPa. The highest compressive strength was recorded as 31.14 MPa in the 1% GO added sample, and the lowest compressive strength was recorded as 8.04 MPa in the 1.5% GO added sample. In addition, it was understood that the mechanical properties did not increase regularly with the increase of graphene oxide reinforcing.

Malzeme bilimi ve teknolojilerinin gelişmesi daha kaliteli, sağlam ve dayanıklı malzemelerin üretilmesine imkân sağlamıştır. Bu gelişmelerin temelinde ince filmlerin yaygın olarak kullanılması ve ince film üretim teknolojilerinin gelişmesi etkili olmuştur. İnce film üretim teknikleri akademik araştırmalarda, teknolojik uygulamalarda ve birçok endüstriyel faaliyette yaygın olarak kullanılmaktadır. Hazırladığımız çalışmamızda temel ince film üretim teknikleri incelenmiş, ince film üretiminde kullanılan her bir temel tekniğin sahip olduğu avantajlar ve dezavantajlar tartışılmış ve ince filmlerin potansiyel uygulama alanlarına değinilmiştir.
