Microbial Corrosion

Microbial Corrosion

Microbiologically Influenced Corrosion (MIC) is a significant form of material degradation caused by the metabolic activities of microorganisms. This phenomenon poses substantial challenges across various industries, including oil and gas, maritime, and water treatment sectors.MIC occurs when microorganisms, such as bacteria, archaea, and fungi, colonize metal surfaces, forming biofilms that alter the local electrochemical environment. These biofilms can lead to the production of corrosive...

Surface Membrane Barriers

Surface Membrane Barriers

The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...

Background:

Polymeric films with antireflective and hydrophobic properties are crucial for electronic displays.
Integrating antimicrobial characteristics into these functional films presents a significant design challenge.

Purpose of the Study:

To design and fabricate a multifunctional nanostructured polymer film with antireflective, hydrophobic, and antimicrobial properties.
To evaluate the optical, hydrophobic, and antimicrobial performance of the designed nanostructure.

Main Methods:

Rigorous coupled-wave analysis was employed to design the nanostructure with specific dimensions (300 nm period, 3.0 aspect ratio).
Poly(methyl methacrylate) (PMMA) films were fabricated with the designed nanostructure using nanoimprinting.
Optical reflectance, hydrophobicity, and adhesion properties were characterized and compared to flat surfaces.

Main Results:

The fabricated nanostructured film exhibited excellent antireflective properties with less than 0.5% reflectance across the visible spectrum.
The nanostructure demonstrated significant hydrophobicity and antimicrobial characteristics.
The nanoimprinted film showed reduced adhesion compared to the flat control surface.

Conclusions:

The designed nanostructured surface is multifunctional, offering a combination of optical, hydrophobic, and antimicrobial benefits.
This technology is suitable for producing advanced protective and hygienic polymer films for portable electronic device displays.
