Background:

• Magnetic polymer composites are gaining interest for biomedical applications.
• Disinfection methods are crucial for materials used in clinical settings.
• Understanding the impact of disinfection on material properties is essential.

Purpose of the Study:

• To investigate the effect of Ultraviolet C (UVC) irradiation on the mechanical properties of composite polymer magnets.
• To assess the chemical changes on the surface of the material after UVC exposure.
• To evaluate the suitability of UVC as a disinfection method for these materials.

Main Methods:

• Mechanical testing: Tensile tests (ASTM D3039) and compression tests (ASTM D3410).
• Surface analysis: Energy Dispersive Spectroscopy (EDS) to quantify elemental composition (Carbon, Oxygen, Iron).
• Statistical analysis: T-test to assess the significance of UVC irradiation effects.

Main Results:

• Tensile transition force increased from 0.41 kN to 0.58 kN post-UVC.
• Compression yield force increased from 4.9 kN to 6 kN post-UVC.
• Carbon content increased from 71.69% to 78.56%, indicating improved surface hardness.

Conclusions:

• UVC irradiation significantly improves the mechanical strength (tensile and compression) of composite polymer magnets.
• UVC treatment beneficially alters the surface chemistry, enhancing material hardness.
• UVC irradiation is a promising disinfection method for composite polymer magnets in biomedical applications.
