New research develops fingerprint-resistant, room-temperature coating for polycarbonate substrates

A new study published in the journal Applied Surface Science demonstrates the efficient fabrication of fingerprint-resistant room temperature coatings on polycarbonate substrat.

Research Background Optical materials, such as screens, lenses, and shields, require surface cleanliness and high optical transmission to function proper.

Therefore, designing coatings that resist surface contamination is a critical but challenging ta.

These materials have excellent water vapor resistance, helping them fight oil and water that can be present on the surface of optical devices and limit their functionali.

These materials enhance the surface's anti-fingerprint and self-cleaning applicatio.

Since oil possesses a lower surface tension than water, developing superhydrophobic materials is a challenging ta.

In recent years, researchers have developed a number of key criteria, including surface roughness and low surface ener.

Manufacturing methods have been developed in recent years using chemical etching to increase the surface roughness of substrates and to deposit low surface energy organic coatin.

Polymer lenses and optical devices have received attention in recent years due to their impact resistance, light weight and shaping potential, making it increasingly necessary to have anti-fingerprint and self-cleaning capabiliti.

The study, published in Applied Surface Science, demonstrates a simple and effective fabrication method for applying hydrophobic coatings on polycarbonate substrates to improve their oleophobicity and superhydrophobicity while maintaining high Transparency and Optical Properti.

The coating is composed of a thin film of nanoporous silica particl.

Using this simple and efficient fabrication process, the authors fabricated a coating with excellent anti-fingerprint and anti-reflection properti.

The coating exhibits good mechanical properties, is very stable, and exhibits strong adhesion to polycarbonate substrat.

US military standards were used to evaluate the abrasion resistance and adhesion of the prepared coatin.

The durability of the coating was further assessed by rubbing the surface of the sample with a cheesecloth p.

Summarize

This study demonstrates that pulsed laser deposition is suitable for depositing superhydrophobic coatings on polycarbonate substrates to enhance the material's resistance to surface contamination and impart self-cleaning properties to optical devic.

This area of ​​research is a relatively new one, and this study provides a guide for future researchers on how surface structures can enhance the anti-fingerprint properties of polycarbonate optical lenses and devic.

Furthermore, it demonstrates that the as-prepared coatings maintain high levels of optical transmittance and transparency, which are critical for commercial applicatio.
