Introduction
Folding handles are widely used in various fields, such as luggage, furniture, and outdoor equipment. However, the folding handles are prone to accumulate fingerprints and stains, which not only affect the appearance but also reduce the service life. Therefore, it is necessary to develop anti-fingerprint and anti-stain technology for folding handles.
Research Methods
The research on anti-fingerprint and anti-stain technology for folding handles mainly includes the following aspects:
- Surface modification: The surface of the folding handle can be modified by physical or chemical methods to improve the anti-fingerprint and anti-stain properties. For example, plasma treatment, coating, and etching can be used to change the surface energy and roughness.
- Material selection: The material of the folding handle can affect its anti-fingerprint and anti-stain properties. Materials with low surface energy, such as fluoropolymers and silicones, are often used to reduce the adhesion of fingerprints and stains.
- Structural design: The structural design of the folding handle can also affect its anti-fingerprint and anti-stain properties. For example, the use of curved surfaces and textures can reduce the contact area between the handle and the fingers or stains.
Research Progress
Currently, many researchers have made progress in the development of anti-fingerprint and anti-stain technology for folding handles. For example:
- A research team from the University of California, Los Angeles, developed a superomniphobic coating that can repel various liquids and prevent fingerprints on the surface of the folding handle.
- A research team from the University of Michigan, Ann Arbor, designed a folding handle with a microscale texture that can reduce the contact area between the handle and the fingers or stains.
- A research team from the University of Tokyo, Japan, developed a folding handle made of a fluoropolymer material that can repel fingerprints and stains.
However, there are still some challenges in the development of anti-fingerprint and anti-stain technology for folding handles, such as the durability and cost of the technology. Further research is needed to overcome these challenges and promote the practical application of the technology.
