Adhesion Performance

Titanium and silica oxides nanoparticles were introduced into hybrid silica sol–gel/epoxy coating to enhance the mechanical properties of coatings. Titanium dioxide (TiO2) and silica oxide (SiO2) were chemically synthesised before adding to the prepared silica sol gel coating. X-ray diffraction (XRD), Energy-dispersive x-ray analysis (EDX) and Transmission Electron microscope (TEM) were used to characterize the prepared nanoparticles. The coating was then applied to 3003 aluminium alloy (AA3003) surface. The adhesion performance of different sol gel coating compositions was investigated using shear test to define the influence of nanoparticles on adhesive strength of the coating. The Rockwell C hardness test was used to study the micro-hardness of different compositions of sol gel coating. Also, contact angel was used to investigate the hydrophobicity of the coatings. The results showed that there was a significant improvement of the adhesion performance of hybrid silica sol gel coating due to addition of TiO2 and the hydrophobicity of sol gel coating was increased due to addition of SiO2 nanoparticles.

Biocompatibility Study

Present paper deals with the development of hybrid nanocomposites which combination of Ag doped Hydroxyapatite (Ag:HAP)-Magnetite nanoparticles (Fe3O4NPs) and Chitosan. In this present investigation, we have employed sol–gel method to synthesize Ag:HAP using 5% of Ag concentrations. Furthermore, co-precipitation technique was employed to prepare Fe3O4 NPs and Ag doped HAP was mixed with it to develop hybrid composites. The planetary ball milling technique was used to incorporate the fabricated Ag:HAP-Fe3O4 composite material into the biopolymer chitosan at wt% of 50:25:25 respectively. In Vitro biocompatibility of Ag:HAP-Fe3O4 CS hybrid composites were evaluated by MTT assay using MG-63 cell lines for 24–48 h at 200–1000 μg/ml concentrations. Further, these hybrid composites were characterized by using ATR-FTIR, XRD and SEM techniques. The fabricated hybrid composite was found to be biologically compatible with MG-63 osteoblast cell lines to use in biomedical applications.
