Development of Antimicrobial MgO-CuO/Activated Carbon Fiber

Area of Science:

• Materials Science
• Nanotechnology
• Environmental Science

Background:

• Activated carbon fiber (ACF) is a key material in air purification due to its adsorption properties.
• Developing functionalized ACF with enhanced antimicrobial capabilities is crucial for advanced air filtration systems.

Purpose of the Study:

• To immobilize MgO and CuO nanoparticles onto ACF using (3-aminopropyl)triethoxysilane (APTES).
• To investigate the coating efficiency, structural integrity, and antimicrobial activity of the modified ACF.
• To evaluate the potential of the functionalized ACF for air purification applications.

Main Methods:

• Immobilization of MgO and CuO nanoparticles on ACF via APTES.
• Characterization of coating efficiency and structural deformation of the modified fibers.
• Assessment of antimicrobial activity against *Escherichia coli* and *Staphylococcus aureus*.

Main Results:

• The MgO-CuO/APTES/ACF (DA-MC) sample demonstrated high antimicrobial activity (>90%) against both bacteria after 24-hour treatment.
• DA-MC exhibited the highest coating efficiency without significant structural deformation.
• APTES and high-temperature curing contributed to improved coating efficiency, antimicrobial activity, and structural protection.

Conclusions:

• The developed DA-MC fiber shows excellent potential as an antimicrobial agent in air purification.
• The functionalization strategy effectively enhances ACF performance without compromising structural stability.
• This approach offers a promising route for creating advanced air filtration materials.
