Inertisation of Surfaces of Materials by Functionalized Perfluorinated Molecules

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a method for rendering material surfaces—particularly ceramics, metals, or plastics—extremely inert by covalently attaching functionalized perfluorinated molecules. The resulting treated surfaces are highly resistant to adhesion or deposition by substances or cells, exhibit extremely low surface energy, and have a very low coefficient of friction. The technology provides lasting, durable, and chemically stable superhydrophobic coatings that prevent fouling and unwanted interactions with the environment.

Use CasesContent extracted from patent full text and abstract with AI.

• Medical implants and devices (e.g., stents, heart implants, joint prostheses, dental implants) where resistance to cell adhesion and biofouling is needed.
• Biomedical instruments and equipment that contact fluids or blood, to minimize contamination and clotting.
• Microelectronics and electronic components protection from dust, contaminants, and static build-up due to ultra-low surface energy.
• High-performance ceramic or metallic components in industrial applications vulnerable to wear, corrosion, or material build-up.
• Anti-fouling coatings for sanitary ware, building materials, windows, and consumer products to reduce cleaning efforts.
• Technical and high-performance ceramics used in 3D printing, ensuring the longevity and cleanliness of printed parts.

BenefitsContent extracted from patent full text and abstract with AI.

• Extremely low surface energy providing superhydrophobic and anti-adhesive properties.
• Highly resistant to adsorption and deposition of biological or chemical substances (including cells, proteins, lipids, etc.).
• Long-lasting stability due to covalent bonding of the fluorinated layer, ensuring durability against mechanical and chemical wear.
• Significant reduction in surface friction, which is beneficial for moving parts or components.
• Prevents biofilm formation and fouling in medical and industrial applications, reducing maintenance and risk of complications (e.g., thrombosis, infections).
• Retention of original mechanical properties (e.g., hardness, conductivity) of the underlying material, particularly in high-performance ceramics.
• Applicable to diverse materials, including ceramics, metals, plastics, and glass, offering broad industrial relevance.
• Potential for selective or patterned surface modification, enabling advanced functional designs.

Patent Abstract

The invention relates preferably to a method for inerting material surfaces, preferably ceramic, metallic or plastic surfaces by means of functionalized perfluorinated compounds in order to form hyperhydrophobic structures. The inert surfaces that can be or are produced in this way have an extremely low surface energy, are resistant to deposits of substances or cells and have a very low coefficient of friction. The invention also relates to possible uses of the inert surfaces in practice.
