Abstract Scope |
Silane Treatment is a type of surface treatment which involves the application of silane, a coupling agent on the surface of a material to improve surface adhesion and bonding. Magnetic powder, i.e., Strontium ferrite (SFO), was treated with varying concentrations of silane using different mixing experimental setups. The treated samples were characterized using Thermogravimetric analysis (TGA), X-ray photoelectron spectroscopy (XPS), Scanning electron microscopy (SEM) and Vibrating sample magnetometer (VSM). The silane retention was confirmed by EDAX and the mixing treatment to get a homogeneous distribution of silane on surface of the SFO powder was optimized. XPS measurements suggest the presence of approximately 1 monolayer of silane on the SFO particles. The magnetic properties of the non-treated and treated SFO powders were compared and no change in the magnetization was observed. Following the treatment, 10 wt. % PA-12/SFO filament were manufactured by a twin-screw extruder. Preliminary 3D printing experiments of mechanical test samples show that the flowability of the silane treated filament differs from the untreated material. |
